What is LED TV ?
What is an LED TV? The simple answer is – an LED TV is an LCD TV that uses light emitting diodes (LEDs) to illuminate the LCD display.
For a full explanation keep reading and I will explain everything you need to know about LED televisions.
What Is The Difference Between LED and LCD TV
A common decision pondered by many consumers when shopping for a TV is whether to buy an LCD or LED TV.
However, strictly speaking they are both the same thing because an LED TV is still ‘classed’ as an LCD TV.
This is because an LED TV is simply and LCD TV that uses LED lights to illuminate the LCD panel rather than fluorescent lamps which had been used prior to the introduction of LEDs.
A more accurate term for describing them is LED-lit LCD TV, or simply LED LCD TV.
The reason is two-fold, firstly it provides a simple way to differentiate between the two varieties of LCD technology.
But also, upon the introduction of LED TVs, I’m sure that from a commercial point of view ‘LED TV’ was considered more of ‘catchy’ marketing phrase which would ultimately attract more consumers and result in more LED TVs being sold.
For your typical shopper this makes the whole LED or LCD TV argument an even more confusing affair. So why do many manufacturers categorise their TVs using the phrase LED TV?
Anyway despite the phrase ‘LED TV’ being somewhat inaccurate, it is the term that has been widely adopted to describe an LCD TV that uses LED lighting to illuminate the display.
LCD CCFL Backlight
What is an LCD backlight?
Before the introduction of the Samsung LED TV brand and its associated marketing campaign in 2009 which heavily influenced the use of ‘LED TV’ as a commonly used phrase,
It is worth pointing out that TVs that used LED backlights had actually been in existence since the first Sony LED TV was released in 2004.
Unlike other ‘self-illuminating’ technologies such as OLED displays and plasma TVs where the display panel emits its own light,
LCD and LED TVs require an additional light source to make the pixels of the LCD panel visible.
The Liquid Crystal Display which is used in LCD TVs is made up of a thin layer of liquid contained between two layers of glass.
The liquid crystal layer is manipulated when an electric current is applied to it. In order to make the changes in the liquid crystal layer visible to the viewer, the panel is illuminated from behind and by a backlight.
Before the introduction of LED TVs, Cold Cathode Fluorescent Lamps (CCFL) was the sole method used for backlighting.
The fluorescent lamps are situated horizontally behind the full width of the LCD panel. Where LED TVs differ is rather than using CCFLs they use LEDs to provide the backlight.
Types of Backlight
To complicate matters even further, the term LED TV is itself a rather broad phrase which encompasses many variations of LED TVs which employ different LED backlight technologies.
There are two different types of LEDs which can be used in two different configurations, consequently this produces some distinctly differently results.
The two types of light emitting diodes used in LED TVs are white LEDs and RGB.
White LEDs actually produce a blue’ish light which is negated by using a sulphur coating to make it ‘whiter’, this results in a quality of light that is comparable to that produced by CCFLs.
RGB (red green blue) LEDs use all three primary colours to produce a broader spectrum of light in comparison to either CCFLs or white LEDs, which in turn improves the range of colors (gamut) produced by the LCD panel.
Full Array LED TV Backlight
Full Array LED TV with local dimming
This type of LED TV produces the best results. It involves the use of more complicated technology which also makes it the most expensive option.
Using this method the LEDs are placed in an array across the whole of the area directly behind the LCD panel.
The LEDs are divided into zones which can be separately controlled so that they can be independently turned on or off.
The number of LEDs and the size of the zones vary between different brands and screen sizes.
This arrangement provides the ability to simultaneously increase or decrease the brightness in different areas of the display, this produces superior black levels and improved contrast.
Because the LEDs are placed directly behind the LCD panel, the uniformity of the backlighting is improved in comparison to edge-lighting (see below),
However it can introduce another problem known as blooming. This is when the light from a brightly lit LED zone unintentionally illuminates an adjacent dimmed area of screen covered by an adjacent zone.
To the viewer a bright on-screen object can appear to have an unwanted glow around it. This backlight method can also use the RGB variety of LEDs which as explained above has a wider color gamut.
Full Array LED TV without local dimming
This is not a very common method of backlighting. As you would expect, it works the same as the method above but without the abilities of a locally dimmable backlight.
When used with RGB LEDs it can produce better colors. But when used with white LEDs it is produces quality comparable to that of a standard CCFL LCD TVs as the fluorescent lamps are simply substituted with LEDs without any of the benefits provided by RGB LEDs or local dimming.
Edge Lit LED TV
LED edge-light and diffusser panel
Edge-lit LED TV without local dimming
This is the most commonly used method of LED back lighting used in LED TVs today. It is responsible for the super slim designs of TVs which can be as thin a 1 inch as well as being very light in weight, which are particularly beneficial when wall mounting the TV.
As the name suggests the LEDs are positioned around the edges of the LCD panel and the light produced is diffused through the LCD panel via something called a ‘light panel’ situated behind it.
It is this method of redirecting the light through the LCD panel which can result in uneven brightness of backlight levels when implemented badly.
In practical terms this results in the picture appearing brighter towards the edges of the display compared to the middle and can be more noticeable when viewing from a wide angle.This method uses white LEDs and so does not benefit from their improved color gamut.
Edge-lit LED TV with local dimming
This is a hybrid backlight method that attempts to combine the benefits of edge and full array backlighting methods, i.e. maintaining a slim design combined with improved blacks and contrast.
It works by dimming the edge-light in the same way that a full array can dim individual zones.
However, as the LEDs are only situated around the edges and not the full area behind the panel, this method is never going to have the level of control of a full array.
This method does improve the blackness levels that are possible but it can also actually make the negative effects of blooming worse.
Benefits of LED TV technology
Also some people would argue that the issue is overblown because the savings in electricity costs for a 60 inch LED TV in comparison to an equivalent CCFL LCD when uses for an average of 6 hours per day equates to less than $50 per year.
Whilst it all helps to contribute towards reducing carbon emissions, it will take a good few years to recoup the extra investment required to own an LED TV compared to a standard LCD TV.
However when comparing power consumption of LED TV vs plasma TV, LED TVs are the clear winners as they use half the power of an equivalent plasma TV.
Improved energy efficiency – Depending on which figures you believe, LED TVs are said to be 10-40% more efficient than standard LCD TVs.
It is difficult to obtain an exact figure for this unless you compare a CCFL LCD with an equivalent LED TV model.
Because LED TVs are more expensive they tend to have more advanced technical features such as auto-brightness and auto-power off which means they use less energy for reasons other than the improved efficiency gained from the LED backlighting itself.
Environment friendly – When the first Samsung LED TVs were released, as well as being more energy efficient it was claimed that the materials used in the manufacture process contained less harmful materials such as mercury.
However one thing that we weren’t told is that LEDs contain other harmful materials such as arsenic and gallium.
Improved reliability – There can be no doubt that overall LED TVs are more reliable and durable than LCD TVs.
The quoted lifespan of an LED TV is 100,000 hours which is approximately 50% longer than the figure for standard LCD TVs.
However this equates to 11 years of continuous usage, or 30 years if used 8 hours per day making it more likely that another part of the television will fail before the LED backlighting does.
A more significant point than reliability is that CCFL backlights actually degrade in performance over time.
The brightness of CCFLs as well as the whiteness of the light produced deteriorates the more the TV is used and the older the TV gets.
This affects quality of the picture which may become noticeably duller before the LCD TV actually fails.
LED TV Problems
LED TV problems
LED lighting uniformity example
Having pointed out the many benefits of LED TVs, it would be unbalanced not to mention a couple of common LED problems.
The first is an issue seen with all LCDs regardless of the type of backlight used and it relates to the viewing angle. Unlike plasma TVs,
The picture quality is reduced when viewing both LCD and LED TVs from wider angles. The use of LED backlights has done little to improve this situation.
Second is the previously mentioned issues relating to the performance of LED backlights. As many current LED TVs models use edge lighting,
They are prone to the poor uniformity of backlighting and as well as blooming effects when local dimming is employed. Neither of these problems are issues with plasma TVs.
What is Full HD 3D TV?
3D TV is a hot topic and full HD 3D TV is a term that is frequently used but not always fully understood.
Common questions consumers might ask are – What is full HD TV? Are all 3D TVs – full HD 3D capable? And what do you need for a full HD 3D TV setup?
To set about explaining this you first need to know that there are two types of 3D TV technology commonly used in home 3D TVs and they are called – passive 3D TV technology and active 3D TV technology.
There are many differences between the two technologies, of which the main difference is the resolutions of the 3D images produced on screen.
The thing that the average person might find confusing is this – if both types of 3D TV technology utilize a full HD display (also known as 1080p), then surely they are both full HD 3D TV capable?
Well the answer is no, both do NOT produce full HD 3D. This is because of the way that the display is used to produce the 3D effects.
Both passive and active 3D TV involves producing separate images for the left and right eyes, however this is where they do things differently.
3D TV Complete Guide
If you are considering replacing your current TV with a newer model, then you will be faced with the choice of whether to buy 3D TV or not.
For the average consumer this raises some really basic questions such as – What is 3D TV and Is 3D TV worth it?
This 3D TV guide should help to answer any questions you about the subject of 3D television.
The Future of 3D TV
3D TV technology has been around for some time, but is only very recently that we have seen the popularity of 3D TV take off in a big way.
Many consumers still have doubts about the future of 3D TV, and because of the significant investment required they find themselves asking is 3D TV worth it, or is will it just be a passing fad?
But don’t fear, 3D TV is set to be with us for the long term. More and more 3D content is becoming widely available with producers of 3D movies, 3D TV channels, 3D games as well as 3D TV manufacturers all being fully committed to the future of home 3D TV.
It is predicted that 3D TVs will make up 40% of all TVs sold worldwide within the next 4 years as 3D TV is adopted worldwide.
However, relatively speaking 3D TV is still in its infancy. 3D TV technology has come a long way over the last couple of years and has improved massively.
It is fast becoming a standard feature in the higher end models of televisions and will continue to develop at a fast pace.
What is 3D TV?
3D TV is the common term used to describe the 3D technology available to home users which enables the viewer to watch visual content with stereoscopic effects.
Prior to the introduction of 3D television a couple of years ago, all TV content was only viewable in 2D – meaning that images were limited to two dimensions which are height and width. 3D technology adds a third dimension to this – depth.
How Does Home 3D TV Differ From 3D Cinema?
Most people have experienced a 3D cinema movie which uses passive 3D glasses. The obvious difference between home and cinema 3D experiences is the size of the screen.
Even when compared to the largest 60 inch 3D TV models that are now available for home use, 3D cinema screens are so large that they occupy much more of the viewers’ field of vision which provides them with a more immersive viewing experience.
3D TV Disadvantages
Even when seated as close to a home 3D TV as is recommended, much less of the viewers’ vision is taken up by the 3D TV screen and the rest of the viewers’ peripheral vision is taken up by the TVs surroundings.
In fact, it is advisable not to sit too close to a 3D television, doing so could cause the viewer to experience eyestrain and headaches and as is discussed later sitting too close to a 3D TV can change the viewing angle which in turn affects the quality of the 3D images produced (I will expand on this a bit later).
The recommended viewing distance for a 60 inch 3D TV is approximately 8 feet, at such a distance it would be difficult to accommodate a larger group of people at an acceptable viewing angle which doesn’t compromise the effectiveness of 3D viewing.
It is inevitable that for larger groups of viewers that they will have to be seated further away from the TV which will mean that the 3D experience will not prove to be as immersive as in a big screen 3D cinema.
3D TV Advantages
However, one of the advantages of 3D TV compared to 3D cinema is the level of control that many of the high-end 3D TVs on the market have.
The better 3D TVs on the market have features which enable the viewer to fine tune home 3D TV settings according to their preference,
Something which is obviously not possible in a 3D Cinema where a happy medium that satisfies all the viewers is the best that can be expected.
Other 3D TV Viewing Problems
Before deciding to buy a 3D TV there are some issues which could possibly affect your enjoyment of 3D TV which you should know about in advance.
The first of these problems is definitely something that you should be aware of before going out and buying a 3D TV.
It has been medically recognised that a small percentage (estimated at about 5%) of the population are affected by something called ‘Stereo Blindness’ whereby the viewer cannot perceive the depth of stereopsis.
To these viewers 3D TV images will appear flat, more like 2D than 3D. And also for some viewers who suffer from stereo blindness 3D TV images can cause headaches, nausea and eyestrain.
The level to which viewers are affected by these side effects differs from one person to the next in varying degrees.
The symptoms described are more likely to occur when viewing for longer periods without breaks and where the 3D effects are more extreme.
It is also more common for younger viewer to suffer from these symptoms than older viewers. It is not necessarily that 3D TV technology is directly to blame for the problems experienced by some viewers,
It is more a case that excessive and badly produced 3D effects contained in 3D content is more likely to produce these adverse reactions especially when viewed for long periods of time.
Whatever the cause of these viewing problems, if you are considering buying a 3D TV it would be wise to experience viewing a 3D TV for yourself in a TV store, or even better than this would be if a friend or family member of yours already has a 3D TV,
Why not invite yourself round to watch a 3D movie to see if 3D TV is to your liking or if it is likely to cause you any of the ill effects described.
What Do I Need To Watch 3D TV?
To enable you to watch 3D TV you will need the following things –
• Obviously you will need a 3D compatible TV.
• You need a pair of 3D glasses for each member of your audience. Most of the current models of active 3D TVs on the market today come with 1 or 2 pairs of active shutter 3D glasses.
As active shutter glasses cost anywhere from $50 to $150 this is something that needs to be taken in to consideration.
If you have a potentially large audience of either family or friends, then equipping them all with their own pair of 3D specs is going to be an expensive job.
• A 3D TV and glasses on their own is no use without any 3D content and so you are going to need a device capable of outputting 3D content, such as a 3D Blu-ray player,
A satellite or cable receiver with a subscription to a 3D TV channel or a 3D games console such as a Sony Playstation.
• In addition to all this 3D hardware, you are going to need the 3D content itself. This is 3D content that is material that is specifically produced for use on 3D TVs.
It can take the form of 3D content broadcast over satellite or cable TV. All of the specialist 3D TV channels that are currently available (other than a small amount of free demo material) are subscription services that will cost you and extra premium on top of what you are paying for normal 2D channels.
The most common form of 3D content available at this moment is 3D Blu-ray movies. However there are currently less than 100 3D Blu-ray titles available for purchase.
Some of these are blockbuster movies that you may already be familiar with, others are 3D documentaries and animated film titles. All of these 3D TV compatible titles can be identified by the 3D Blu-ray logos which they carry.
3D TV Without Glasses
The biggest issue that consumers have with 3D TV is the requirement having to wear 3D glasses. Currently all production 3D TVs require the viewer to wear 3D glasses to achieve the 3D effects.
Common complaints with this is that they are an inconvenience and uncomfortable to wear, and in some cases cause headaches and eye-strain. What consumers ultimately want is 3D TV without the glasses.
So before we get stuck in to how 3D TV works there is a question on everyone’s lips that needs addressing – is 3D TV without glasses possible?
The simple to this is -no! 3D TV manufacturers are putting great effort in to developing 3D without glasses TV models.
We have seen prototype Philip, Toshiba and Samsung 3D TV without glasses being demonstrated at recent TV industry shows and events. However,
There are many problems to overcome before this becomes a commercially viable reality and you will be able to buy 3D TV without glasses in retail stores.
So, as a consumer, if you are concerned that any investment you make today in buying a current 3D TV model that requires 3D glasses will be surpassed by a new 3D TV without glasses in the near future, then don’t worry because this is quite some way off, probably at least a few years from happening.
How Does 3D TV Work
There are currently two types of 3D television technology – Passive 3D and Active 3D (for a full explanation see this Active 3D TV Vs Passive 3D TV Review). Both types of 3D technology require the use of 3D TV glasses.
The choice between buying an active 3D Vs passive 3D television is the fundamental choice that you face as a consumer.
Active 3D TV
Active 3D televisions were the first type to appear on the market and are characterized by the heavier and bulkier type of active shutter 3D spectacles. Active 3D TVs achieve the depth of images using a method called ‘alternate frame sequencing’.
This involves producing two separate sets of images (one for the viewer’s left eye and one for the right eye).
In simple terms this method involves filming the subject with two cameras from slightly different angles, in the same way as human eyes view an object from two slightly different angles.
Then, as the term ‘alternate frame sequencing’ would suggest, these images are displayed in an alternate sequence by the TV.
The active shutters built in to the glasses ‘open and close’ so that the viewer only sees the corresponding image for either the left or right eyes.
To be able to do this the active shutter 3D glasses must be synchronized through the transmission of a signal either using infrared or Bluetooth.
Passive 3D TV
Passive 3D TV (also referred to as polarisation 3D), has only become commercially available more recently with LG being the only major manufacturer currently pushing Passive 3D TV technology.
Passive 3D TV achieves 3D images differently, rather than displaying the two sets of images intended for the left and right eyes in an alternate sequence,
They display both images on the screen at the same time. Through the use of the polarized lenses of the glasses, half of the image is filtered out for each of the left and right eyes.
Both methods have the same end result – the viewer’s left and right eyes sees a slightly different image which are filmed (or created) from a slightly different perspective.
The viewers’ brain combines and interprets these images as one single 3D image containing depth.
Active Vs Passive 3D TV Comparisson
3D TV Resolutions – Active 3D TVs are frquently marketed Full HD 3D TV, because each eyes view a separate image, each eye views the full resolution that the television is capable of.
If this max resolution is 1080p then the viewer will receive full HD 3D TV (1080p). Because passive 3D TV uses a single frame which is ‘split’ between the left and right eyes, the resolution is in effect reduced by approximately 40%.
3D TV Refresh Rates – Because active 3D TVs display two sets of sequential frames for the left and right sides, the refresh rate is effectively halved for each eye. Eg for a 240 Hz 3D TV each eye would receive 120 frames per second.
The negative impact this has is that motion can become blurred. For passive 3D TVs the viewer receives the full refresh rate of the TV for both eyes and so motions blur is less likely.
3D TV Cost – Passive 3D TVs are typically cheaper than equivalent active 3D TV models. Also active shutter 3D TV glasses cost between $50 and $150,
Where as passive 3D TV glasses cost less than $20 (and for this reason passive 3D TV models frequently include more pairs of 3D glasses with the TV).
There is a trade off between the two technologies because of the specific qualities that each type of technologies produce, the major points can be summarized as follows –
Advantages of Active 3D TV
• Are capable of producing Full HD 3D TV picture (when used with a suitable 1080p 3D input source such as a 3D Blu-ray player).
Disadvantages of Active 3D TV
• More vulnerable to flicker and ghosting due to the active shutter 3D glasses.
• Reduces the brightness of the images.
• Active shutter 3D glasses are typically manufacturer specific, more expensive, require a power source and are heavier and therefore more uncomfortable to wear.
Advantages of Passive 3D TV
• Passive 3D glasses are very cheap, don’t require a power source and are lighter and therefore more comfortable.
• Passive 3D TVs are not as vulnerable to flicker or ghosting of images.
• Does not reduce the brightness of 3D images as much as active 3D TVs.
Disadvantages of Passive 3D TV
• Cannot produce Full HD 3D TV images (the resolution is half that of active 3D).
Also both passive 3D and active 3D TVs are affected by viewing angles. The effectiveness of an active 3D TV is adversely affected the wider the horizontal angle that the viewer is seated in relation to the TV.
Passive 3D TVs effectiveness is reduced when viewed from a greater vertical angle. The passive 3D TVs currently seem to have a fairly narrow vertical viewing angle which only becomes a problem if seated in a position where the TV is not close to being at eye level.
As you can see the decision between the two types of 3D TVs available is not an easy one. The 3D TV pros and the cons between active or passive 3D TV varies between manufacturers and models and how well the technology is implemented, so there is no definitive answer as to which is the best 3D TV.
Another factor is that preference for either passive or active 3D TV is subjective, meaning that some of the benefits or disadvantages which are associated with one type may not be as relevant for the next person.
For instance if you are going to be watching a lot of 3D Blu Ray movies then an active 3D TV might be the way to go for you. However if you aren’t, and your favourite sports channel is not broadcast in Full HD 3D then a passive 3D TV might be the choice for you.
Another issue is cost, if your budget won’t stretch to buying an active 3D TV with multiple pairs of expensive active 3D glasses, then a more affordable passive 3D TV with the cheaper 3D specs might be the option that suits you.
Other 3D TV Problems
3D crosstalk or ghosting as it is also commonly known is one of the most common problems with 3D TV.
It is caused when the left and right sided images are not separated correctly causing them to overlap thus creating a double image.
The seriousness of the problem varies between models, technologies and is affected by the quality of the 3D content.
A common opinion on this matter is that generally speaking LCD / LED 3D TVs are more prone to this problem than plasma 3D TV models.
A contributing factor for this could be that because LED TVs produce brighter images than plasmas, and ghosting effects are more noticeable when bright objects are displayed adjacent to dark objects, the brighter displays of LCD and LED TV amplify the problem.
Judder is another problem which has long existed with 2D TVs. It happens when the scenes displayed contain horizontal movement.
This problem can appear more severe with 3D TVs but depending on the quality of the TV it can be eliminated or reduced by video processing techniques.
The final issue to be aware of is that as well as reducing the brightness of 3D content compared to normal 2D viewing,
3D glasses can also add a slight tint of unnatural color to 3D pictures. In well implemented 3D TVs this can be corrected by the TV adjusting the colors accordingly to compensate for any color bias whilst in 3D mode.
3D TV Conclusions…
After reading much of this article which points out many of the issues to be aware of with 3D TVs it may be enough to put you off buying a 3D TV.
However don’t be deterred, all of the problems mentioned are generally not an issue with the best 3D TV models available on the market today which will wow you.
So if you are looking to buy a 3D TV, you should sample as many 3D TV models as you can in order to establish your own preference between both active and passive 3D TVs as well as between LED 3D TV Vs Plasma 3D TVs.
However the best plasma 3D TVs aren’t in a price-range that is within everyone’s reach so choosing an LED 3D TV might be a better way to utilize your budget. Either way, do your research thoroughly and you will be blown away by what 3D TV has to offer.
If you were to take a poll of what 3D TV is best from all of the reviews available, Plasma active 3D TV would probably win the contest based on the quality of the 3D pictures that they produce.
One of the current 3D plasma TVs which is consistently regarded as the best 3D TV is the Panasonic VT30.
Samsung UN60D7000 60 Inch Full HD 3D LED TV
First you need to understand that when displaying content, all TVs display many images per second (each image is called a ‘frame’).
Each frame is made up of many horizontal rows of tiny dots or pixels. For full HD TV there are 1080 horizontal rows of pixels per frame (hence the term 1080p).
Passive 3D TV uses a single frame to display both the left and right images at the same time.
Within each frame, alternate lines are used the left and right images, or to put it another way the odd lines display the left image and the even lines contain the right images.
Active 3D TV uses sequential frames to display left and right images. So, one whole frame displays the left sided image and the next whole frame displays the right sided images. Two frames a re required to display the left and right sides.
In both of the above methods, the user must wear 3D glasses which separate the left and right images to only be visible to the viewer’s corresponding eye.
Because passive 3D TV splits a single full HD frame between both eyes, the resolution is in effect being halved.
And because active 3D TV uses two whole full HD TV frames, the full 1080 resolution is visible by both eyes and hence the full HD 3D TV experienced is achieved.
However, in order to actually view full HD 1080p 3D TV, as well as buying a full HD 3D TV set, you are going to need some 3D content to play on your TV.
To do this you are going to need a 3D enabled Blu-ray disc player and some Blu-ray 3D discs. There is now quite a lot of cable and satellite channel providers who provide 3D content,
However these won’t be broadcast in full HD 3D, they well be in lower resolutions because the bandwidth requirements for 1080p 3D are too high.
Out of the major 3D TV manufacturers, who use passive 3D and who uses active 3D? Well at this point in time only LG and Philips use passive 3D TV, all other brands of 3D TVs use active 3D TV.
Panasonic Full HD 3D TV and Samsung Full HD 3D TV are two of the best known brands who you are likely to have seen marketing their TVs in reference to this subject.
However, if you think that the higher resolutions of full HD 3D TVs make them an automatic choice over the lower 3D resolutions of passive 3D TVs then think again.
The resolution is only a small part of the equation, to full understand the difference see this guide – active 3D Vs passive 3D review.
Because whilst full HD TV is superior in terms of it’s resolution, passive 3D TVs have their own benefits too.
Samsung LED TV Buying Guide
The Samsung LED TV models are regarded as the best TVs on the market by many consumers and industry experts.
Over the last 5 years Samsung has seen a meteoric rise to become the market leader of television manufacturers,
Brushing aside the likes of Sony and other electronics manufacturers. LCD-based TVs now make up over 80% of all televisions sold worldwide and 40% of this figure is from LED TVs (of which the majority are sold to the established markets in the US, Europe and the Far East).
So why have Samsung LED TVs become the most sought after TV models? It is simply because the quality. Samsung LED televisions are packed with cutting edge technology which we will now take a look at below.
Samsung Clear Motion Rate
This is Samsungs new measurement for the performance of their TVs. Previously the capabilities of TVs was measured using a number of factors including resolution, refresh rate and response times.
However this is outdated and isn’t a true reflection of performance of modern television sets in which additional factors play a more significant part.
The picture quality of Samsung LED LCD TVs is determined by three things – panel refresh rate, image processing and backlight capabilities.
It is these three factors which determine the Clear Motion Rate (CMR) value and ultimately define the image quality that a particular Samsung LED TV is capable of. An explanation of these three factors is included below.
Samsung Clear MotionSamsung Image Processor – Most TV manufacturers employ image processing in their TVs and attach their own propriety brand names to this feature.
The basic principal behind image processing involves the interpolation of frames to produce smoother motion and the alleviation of video artifacts commonly known as judder.
The speed and effectiveness at which a TVs video engine can perform this task ultimate defines how smooth motion appears on screen.
Overly processed video can also look unnatural to the viewer particularly when watching fast paced on-screen action. The superior image processing capabilities of Samsung LED TVs is regarded as the best in the business producing high clarity images.
Display Refresh Rate – A high refresh rate directly improves the smoothness motion and detailed resolutions because of the increased sampling rate.
The effect is seamless transition of on-screen movement typical of fast paced sports and movies. As many of the models in Samsungs LED TV range are 3D capable,
The increased refresh rates of up to 240 Hz in the top of the range models has a double benefit as it also improves the quality of 3D content.
Samsung Backlight Technology – Samsung are the pioneers of LED backlight technology with a full range of models which employ LED edge lighting. As well as being responsible for the super slim designs that have become associated with the brand,
The output of the backlight is regulated to so that it is synchronised with the refresh of the display so as to reduce motion blur and video artefacts.
Samsung Ultra Thin Bezel and 1.2 inch side profile
Samsung Ultra Slim Bezel
Samsung LED LCD TV are undoubtedly the most stylish TVs on the market today. As already mentioned thanks to Samsungs revolutionary edge LED backlight system their LED TV models have the thinnest profiles available on the market.
Additional to this they also have what Samsung calls an Ultra Slim Bezel so that the bezel or the body of the television which surrounds the LED TV panel is so thin that it is almost unnoticeable when viewing the TV.
This is said to enhance the viewing experience as the viewer only sees the images on display without being bordered by a bulky glass or plastic bezel seen in the designs of other brands of TVs.
As well as looking attractive, both the slim profile and ultra thin bezel has the added benefit of reducing the overall space required to situate Samsung LED TVs in your viewing area, this is especially true when wall mounting Samsung TVs.
Samsung Micro Dimming Plus
Samsung Micro Dimming Plus divides the image in to multiple areas for improved contrast levels
This is only available in the top of the range Samsung LED TVs. It is Samsungs solution to reducing a problem characteristic with LCD TVs ,
Where-by areas of on-screen images that are intended to be black actually appear lighter due to the inadequacies of LCD panels being unable to totally block the backlight.
Other methods of over-coming this have included producing TVs that have arrays of locally dimmable LEDs which are situated directly behind the LCD panel.
Where as this solves the problems of producing better levels of blackness it also hampers the physical designs of the televisions in order to accommodate the LED arrays making LED TVs with local dimming heavier and thicker in profile as well as more expensive.
As Samsung LED LCD TV models use edge lighting, the local dimming feature is not possible and ‘micro dimming plus’ is Samsungs answer to this problem.
It is a feature which divides the picture up into small parts analyzing the brightness of each area and adjusting the contrast levels for each part accordingly to produce superior levels of brightness and darkness which also increases the level of fine detail visible to the viewer.
Samsung 3D LED TVs
The hot topic of the moment is 3D TV. Samsung 3D TVs use what some will ague is the superior method of 3D TV technology out the two kinds which are available.
Samsung 3D LED televisions use active 3D methods to deliver 3D content (as opposed to passive 3D).
Samsung LED TVs use Active 3D which produces Full HD 1080p resolution using active shutter glasses
The main benefit of active 3D TV compared to passive 3D TV is that it capable of producing full HD 3D (1080p) images, something passive 3D TVs are not capable of doing.
This means with a Samsung 3D LED TV you will enjoy 3D TV at the highest resolution possible. However, note that you will require a source of 1080p 3D content either from your satellite or cable TV provider or from a 3D Blu-ray player.
The active 3D TV technique has a couple of disadvantages, which includes a reduction in brightness due to the filtering effect of 3D glasses and effective reduction in refresh rate which causes flicker.
However because Samsung LED TVs are brighter because of the LED lighting systems employed in their design, this compensates for the reduction in brightness from using 3D glasses.
The issue of the effective reduction in refresh rates has simply been compensated for by doubling the refresh rates, (Samsung LED TVs can now have a 240 Hz refresh rate rather than 120 Hz).
Samsung Smart TV Web Apps and Web Browser
Samsung has invested heavily in producing a full range of internet enabled televisions which they have labelled Smart TV.
The features vary from model to model, but what Smart TV has done is transform the modern TV into device which cannot only be used to watch your favourite shows or films, but also it can be used for tasks that were previously on possible through the use of a PC.
Samsung Smart TV
Internet Enabled LED TV
Using Samsung Apps accessed through the TVs menu system it is possible to search for movies, music and TV shows online, interact with your friends through social media and browse the internet using the inbuilt web browser and ‘keyboard’ remote control.
All this is done using an ever expanding range of Samsung Apps which can be downloaded from the Samsung app-store.
There are apps for many services, some of which you may already be familiar with though using a PC including YouTube, Blockbuster Movies, Pandora music, Facebook, Twitter and ESPN to name just a few.
Samsung AllShare and DLNA Connectivity
DLNA technology has bridged the gap which exists between connecting all your multimedia devices within your home.
Previously the various sources of digital music, photos and video stored on your PCs, media players, phones and storage devices were limited to use on the device on which they were stored unless the data was transferred by using cables or transferring memory cards etc.
Samsung AllShare DLNA Connectivity
Connects your DLNA devices to a Samsung LED TV
With AllShare, Samsung LED TVs become the hub of your home media entertainment. Using wireless technology it is possible to view and playback digital media store on other DLNA compatible devices in your home.
The Samsung menu system makes it easy to configure other devices so that you can seamlessly playback movies stored on your PC, listen to music from your media player or view pictures stored on your Smart phone directly on your TV.
Samsung Eco Friendly Designs
As well as being some of the most technologically advanced TV on the market, Samsung LED TVs are also some of the most environmentally friendly TVs available.
Samsung has clearly put a lot of work in to not only meeting Energy Star Standards but exceeding them.
Samsung LED televisions more eco friendly due to the reduced power requirements of the LEDs utilized in their lighting system (when compared to the fluorescent lamps used in conventional LCD TVs),
But additional to this Samsung has also implemented some innovative features to further improve energy ratings including their Eco Light Sensor which detects the intensity the light levels in the room and adjust the picture brightness and contrast levels accordingly.
So rather than having the brightness turned up constantly, Samsung LED TVs will dim the brightness the darker the room gets in order to optimize power consumption.
Not only is this friendly to the environment but it reduces your electricity bill also.
If you are in the market for an LCD television with deep black capability and name brand recognition, then the Sony KDL-HX850 series may hold something of interest to you.
This line of Sony LCDs features plenty of functionality, with elements like Smart TV and heavy duty Gorilla Glass. For more details about this series, read the complete Sony KDL-HX850 series TV review below.
Sony Bravia HX850 LED TV Series Review
Although this series only offers two model choices, they are both common sizes that work well in most home theater, den or living room setups. The model choices are:
Sony KDL-55HX850 55 inches
Overall, the KDL-HX850 does not quite live up to the stunning color and brightness performance of a plasma television,
But for an LCD, it performs across most areas at a rating of excellent or higher. In fact, it competes with other LCD televisions from higher pricing brackets, making it an affordable option to higher end models.
In order to obtain the best quality picture, you may need to calibrate the settings. Most consumer experts seem to feel the Cinema 2 setting for picture mode provides the best performance with most of the advanced settings like black corrector and auto light limiter turned off.
When compared with televisions from other brands on the same price level, the KDL-HX850 comes in a bit under average.
This is mostly due to the fact that, in typical Sony fashion, the television has a difficult time with hues that walk the line between blue and green.
The KDL-HX850 tends to display a bluer version of shades, although it performs well at other colors.
One of the strengths of this television is its ability to reproduce blacks at almost any level and provide distinct shadow detail without ghosting.
When compared with more expensive LCD televisions in this area, the KDL-HX850 tends to come out on top.
Multiple consumer magazine tests have shown the KDL-HX850 to be adept at displaying stark contrast between light and dark scenes and rendering dark-on-dark imagery with enough detail to be almost 3-D.
Overall Video Performance
Sony is known for superb video performance and is quickly making a name for itself in 3D video, so it is no surprise that both of these areas are strong points for the KDL-HX850.
Sony technology makes it possible for the KDL-HK850 to deliver accurate video from a variety of sources and formats without artifacts or distractions.
The television’s 3D performance is excellent and provides minimal crosstalk for an LCD. Although this may not be the best choice for someone looking for prime 3D performance on a regular basis, it is an excellent choice as a television that will need to show 3D movies on occasion.
The KDL-HX850 carries some of Sony’s recognizable design qualities, including a sheet of glass across the entire front and an elegant aluminum ring.
Sony provides a bit of signature sophistication with the edge lighting on the LED panel and you have the option of local dimming.
The lighting is a bit pared down from earlier models, making the set less gaudy and more attractive.
The impact-resistant Gorilla Glass front makes the television durable as well as pretty, meaning owners can worry less about wayward children or active video game fans.
The television is propped on a newly designed stand that features a few curves. If you do not prefer the style of the stand, Sony offers an optional desktop stand that features a contemporary aluminum finish.
The Smart TV portion of the KDL-HX850 does not offer much in the way of new or stand out items, but it does provide full functionality and access to most of the popular apps.
You can access Netflix, Amazon video, Hulu, Sony’s Video Unlimited, YouTube, Pandora, Slacker, Sony’s Music Unlimited, Yahoo, Facebook, Skype, Twitter, Flickr and Picasa, among others.
You can also use Sony’s online media shop to purchase digital video and music for download. As is typical with any television browser, maneuverability via the television remote can feel backwards and slow.
You probably are not going to be replacing your desktop computer, for example. However, the Sony does allow for limited control via a tablet or Smartphone if you download the control app.
The KDL-HX850 is pretty much par for the course when it comes to connectivity. The television features a standard two USB ports and four HDMI ports. Unlike some newer televisions, the Sony features ready analogue inputs, including PC, composite and component.
You can use the television’s integrated wireless capability for internet connections, or connect directly to a home network via an Ethernet port.
The Sony KDL-HX850 provides a strong performance for an LCD television in its price range and also competes with several models that are more expensive.
You will pay anywhere from $2,200 to $2,600 for this television on average, making it a bit pricier than comparable plasmas. However, for those who want a durable LCD screen that delivers overall accurate color and high black levels,
The Sony KDL-HX850 is a great choice. It would make a perfect all-use television in a family or entertainment room, given its capability to perform on multiple video sources.
LG LW5600 3D LED TV Review
There have been many battles fought in the world of home cinema technology, and this LG LW5600 LED TV review will introduce another.
The newest fight is between passive 3D TV vs active 3D TV. The LG LW5600 3D LED TV is one of the first types of passive 3D TV released by LG the primary advocate of passive 3D technology which is set to take on the active 3D TV models of its rival manufacturers.
Along with Samsung, LG LED TV models have become well known for there attractive slim designs and the LG LW5600 does not disappoint.
It measures in at little over one inch in thickness and comes with a sturdy swivel stand. However as nice as this is you will want to know how the LW5600 performs from a technical perspective.
LG 5600 LED TV
LG Infinia 47LW5600 47 Inch Cinema 3D LED TV with Smart TV and Four Pairs of 3D Glasses
In terms of picture quality the LG LW5600 is impressive. With some LED TV models that utilize local dimming back lights, an unwanted effect where-by bright parts of the picture bleed into darker areas can be experienced.
The LW5600 performed particularly well in this area with little light bleeding present. Comparably, images that images which contain both areas of intense bright and darkness were able to be better displayed than other rival TVs models in its class.
The LW5600 is packed with many picture quality related settings which do require some tweaking to achieve a picture of your liking depending upon the input and viewing conditions.
However, generally speaking the navigation of the LW5600 menus and settings is easy, making this an easy job.
The picture quality of the LW5600 not as good as the best plasmas, but then the LW5600 is half the price, and compared to some other more expensive LED TVs it more than holds its own.
Passive 3D performance for the LW5600 3D TV is the big difference between this and its active 3D TV rivals.
The beauty of passive 3D TV is that the 3D glasses are cheap and lightweight making 3D viewing with the LG LW5600 both easier on the eye and on your pocket.
But as advocates of active 3D TV are quick to tell you there is a trade off, and this is that the resolution of passive 3D TVs such as the LW5600 are reduced.
Whilst this is true, how significant a factor are these reduced resolutions, and does this outweigh the benefits of passive 3D TVs?
There is no definitive answer to this, because it depends on a few things – firstly what sources of 3D media you intend viewing, your viewing environment and the importance you attach to cost.
The reduction in resolution of passive 3D TV is noticeable whatever the source of 3D content.
However it is less noticeable with BluRay movies than it is with 3D satellite TV broadcasts. The loss in quality of watching 3D BluRay is more acceptable because of the already high 1080p format of Bluray,
But the loss of resolution for the already compressed content of 3D satellite channels is more noticeable. 3D gaming performance is mixed depending on the console and game being played.
With regards to your viewing environment, it is worth taking in to consideration that passive 3D TVs including the LW5600 have wider viewing angles than active 3D TVs do.
Also when viewed from up close or from a vertical angle (eg when the TV is wall-mounted higher than head-height) the viewer can experience the unwanted effect of vertical lines when viewing 3D pictures.
Therefore passive 3D TVs are particularly good when a larger audience is viewing, because you will have some viewers at wider angles (active 3D TV generally speaking has a narrower horizontal viewing angle).
So if you have a big family and/or lots of friends then passive 3D TV could be more suitable in your circumstances (in addition to the fact that you will need more pairs of 3D glasses for which the passive variety are cheaper by-far).
If you have an unlimited budget then a TV such as the Panasonic VT20 or the Samsung 8000 will offer you better 3D performance but cost you twice as much.
When it comes to getting the best big screen 3D performance for your buck, the 55LW5600 3D TV is great value costing $500 less than other equivalent 55 inch active 3D TVs.
Almost as important as visual capabilities of TVs is the internet features of modern TVs. In this regards LG are right at the forefront of ‘Smart TV’ technology.
The LW5600 comes with a good range of useful standard apps built-in including Netflix, Vudu and Amazon, plus the LG app store provides a wide range optional apps.
One particularly useful app (Plex media client) enables the streaming of media from a local PC installed with Plex media server either using the ethernet connection or Wi-Fi USB dongle.
All things considered, there is not a lot you will find wrong with the LW5600, perhaps other than one thing that has been omitted until now. The audio performance is decidedly average, but this is not uncommon in a lot of the leading brands.
But in summary of this LG LW5600 review, you won’t find many other TVs that are as competitive in terms of price and performance, and so if you are looking at purchasing a 3D TV then give serious consideration to the LG LW5600.
Panasonic DT30 3D LED TV Review
The Panasonic DT30 is one of the manufacturer’s first 3D LED TV models. Panasonic are well known for the quality of their plasma 3D TV models,
But how does this 3D LED TV stand up to their plasmas. The Panasonic DT30 is available in 37 and 32 inch display sizes and comes packed with Panasonics latest features.
In general, the major criticism of active 3D LED TV models in the past has been the presence of 3D crosstalk, where-by the images for the left and right eyes overlap causing a ghosting effect.
The new Panasonic IPS Alpha LED panel eliminates this using faster display technology compared to previous TVs.
The issue of having to wear uncomfortable bulky 3D glasses has also been addressed with the re-design of Panasonic 3D glasses which are now slightly more lightweight and user friendly.
Panasonic DT30 LED TV
Panasonic VIERA TC-L37DT30 37 Inch 3D LED LCD TV
In line with other manufacturers features, the Panasonic DT30 3D LED TV comes equipped with ‘Viera Connect’ for internet connectivity through the use of smart apps.
Viera connect provides easier access to free and paid services with standard apps for Facebook, Twitter and other common online services, plus other optional apps can be downloaded through the Panasonic application store.
A neat feature of the Panasonic DT30 is the possibility to use its USB connections to attach an external device such as a USB hard disk or memory card which can then be used as a video recorder to capture and play back programs received through the TVs tuners.
If there has been one criticism in some previous Panasonic TV reviews, it is the aesthetic designs of their TVs which hasn’t quite lived up to that of their competitors super stylish designs (such as Samsung and LG LED TVs).
Recent Panasonic HDTVs have received a makeover and the DT30 is a big improvement partly due to it being an LED TV which allows for a slimmer design and a stylish small bezel frame.
The conclusion of this Panasonic DT30 LED TV review is a continuation of the manufacturer’s highly regarded ability for producing great quality and technical advanced TVs which are highly recommended.
