There is confusion about LED televisions. LCD televisions require a light source behind the LCD panel. The liquid crystals act as shutters to let light pass and so they crea…te the image. Conventional LCD television use cold cathode fluorescent lighting behind the LCD layer. More recently, LEDs are being used as the light source and they are cooler and more efficient than the CCFL models. However, the LCD technology hasn't changed but these are frequently known as LED televisions. The latest technology to make it to the domestic market is a true LED television, normally being advertised as OLED (Organic Light Emitting Diode). Instead of backlighting and LCD shutters, a red, green and blue LED are used for every pixel on the screen. Each is illuminated as it's needed to create the image. One of the significant advantages is that the screens can be much thinner than other technologies and the power used is lower than LCD televisions. Some models are as thin as 6mm (1/4"). The OLED models are expected to make an impact during 2013 and are likely to replace LCD as the most common display technology in the next few years. LED televisions are not common at the time of writing (2010) but they are expected to make a bigger impact in the future. Although it is a new application, the technology already has quite a history. It is the same type of technology that is used in large outdoor television screen used in concerts and for advertising which have been used for well over a decade.
so...The LED is going to be the latest and the greastest. The LED is going to give more of a brighter color off due to the side lighting instead of the lighting being in the m…iddle of the picture. The LED are going to be more dynamic then an LCD. The LCD is still going to be a really good TV but will be thicker on the bottom due to the flourescent lighting on the bottom Shamelessly copied from the Wikipedia article (which is copylefted, admin ftr) Here are the advantages over standard LCD: Produce images with greater dynamic contrast.With Edge-LED lighting they can be extremely slim. Models on the market can be approximately one inch thick.Offer a wider color gamut, especially when RGB-LED backlighting is used.Less environmental pollution on disposal.Generally 20-30% lower power consumption. The only clear disadvantage is that LED TVs have a higher sales price. From an objective point-of-view (or as much as possible, considering the word "better" is subjective by nature), LED TVs for the win!
An LED TV is considering to be of better quality when compared to an LCD TV. This is because the LED lights used in the panel are considered more energy efficient.
No. Projection TV's use the 3 primary colors, red, green and blue, projected into a mirror then back onto a screen to make the images you see. LCD's, or liquid crystal d…isplays, use liquid to form the images with much more clarity. While there are LCD projection TV's, the flat panels are better. Plasma TV's use a gas to form the images and are considered the best in image quality and resolution, though the newer LED, or light emitting diodes, TV's have an incredible contrast ratio of up to 5 million to 1, and use only a third of the power of most plasmas.
Sony and Samsung are both excellent.
a samsung or lg 3d led tv has to be the best.
It depends what you mean by LED. Liquid Crystal Displays need a light source, as LCDs produce non themselves. This light, used to be provided by Cold Cathode Flourescent L…amps (CCFL). These were delicate, failed after a while and used high voltage to run. Modern LCDs use white, Light Emmiting Diodes to provide the light source. These use low voltage and run cool. They could only be used now, because it took a while for development to produce a good white light, with a high light output. So when a TV is advertised as having LED technology, this is what they are referring to. It is still an LCD TV, but with LEDs providing the light and yes they are better. They use less power and are potentially more long lived. TVs are being developed that use red, green and blue, LED's in a matrix to provide the picture content and light. They are used in very large displays at football stadiums. Small versions are being developed using a flat film with LEDs 'printed' on it. This is called OLED (Organic Light Emitting Diode). So far they can only make small screens using this tech. but they are getting better, but more expensive at first.
Both Sony and Samsung make several somewhat esoteric models of television for specialist markets and these perhaps don't need a mention in an answer as they are not likely to …be ever seen in mainstream stores or catalogues. As specific models change rapidly, no mention of model numbers and prices are made here either. Some opinions and information are set out below by several contributors Sony has a new 4 K Ultra HDTV that costs much more than a working person can afford at $24,999.99 for the 84 inch model It is available to preorder in a 55 and 65 inch models at $5000 and $8,000. They exceed the highest broadcast resolutions currently available and therefore outperform the current HD outputs. Sony is clearly the better brand if you want to purchase the best Brand. Normally any best Brand is not the most economical or the best bargain. Even within the Sony HDTV there is also a Best Model and that is often way more expensive. Sony is the most technologically advanced but is a bit more pricey and could cost you a few hundred more than the Samsung with the same features. Quality of picture and other small factors make the Sony a better choice especially for those who want more class and features. But when you don't want to pay those extra hundred dollars, the Samsung is a great preference. The value for money for a Samsung is much more than anything you could get from any other brand. Simply said the price is Justifiable. One data point: We actually have a Samsung LCD TV and it's amazing. We chose it over Sony because we heard that the Sony's have more TV's that need to be repaired. Another data point: In the last few years, thousands of Samsung customers have suffered from a devastating problem that Samsung has been very slow to respond to. Just google "Samsung lcd tv click capacitor" to see the many people who were impacted by Samsung's decision to use inadequate capacitors in their power supplies. There are several videos on youtube on how to repair this problem; one has over 50,000 views. The most important factors with HDTVs are that 1080p LED LCD HDTVs are better than the other models of LCD HDTVS. That all of a brands top newly released models now are 3D. even if you never plan to use 3D the picture quality is better in 3D models for all the brands. Electronic prices always decrease as newer models are released and it is reasonable to assume that will continue. Many of the discounted HDTVs are either old stock or new production of older models.

It is newer and clearer and provides you with a better viewing experience. However, LED technology, for providing the picture content, is currently more expensive then LCD technology.
LCD screen TVs are brighter than plasm screen TVs which is very good to place in a room with a lot of light. Some LCD TVs have the option to create more dramatic looking contr…ast levels. Also very good about LCD TVs are that they weight less for easier transport and use way less electricity
Although it still depends on its technical specification, in the vast majority of cases an LED TV will be better. LED usually has a sharper image as each pixel is being change…d individually by a different diode meaning that the picture also changes quicker and smoother. LCD TV is also known as Liquid Crystal Display TV. From its name, it uses liquid crystal to produce images on the TV screen. Its thin layer of liquid crystal has tiny cells that produce pixels. As an electric current is applied, its rod shaped molecules respond by bending the light. LCD TVs are quite inefficient in terms of power utilization because the enormous mass of light that is being produced behind the screen is blocked before it reaches the person who is watching the television. LED TVs also known as Light Emitting Diode on the other hand use backlighting technology with the use of LED. Its screen contains blue, red and green LEDs which lights up to produce the correct color. It has two types of backlighting technology: Edge Lighting and Full Array. Its backlighting technology makes it possible to consume 40% less power making it eco friendly.
Some good places to buy high quality TV stands for a LCD TV are Best Buy, Amazon, Dell, Kmart, Kohl's, Meijer, Newegg, Office Depot, Overstock, QVC, Radio Shack, Sam's Club, S…ears, Staples, Target, TigerDirect, and Walmart

In theory, active 3D TVs are supposed to have better image quality than passive models. Passive televisions such as LG split the image lines so each eye sees only 540 lines.… With an active 3D image, each eye sees a full 1080 lines. For resolution, choose an active television. Before buying, do experience both active and passive models and make your own judgment. For non-3D viewing, you must look at the technology used to make the display. Modern TV's use an LED backlight, and some have the capability of local dimming, that is, turning off backlight LED's for areas of the screen that are back. This can make a big difference in the contrast ratio of the screen, and is most noticable during movie titles. For 3D viewing, you should get a chance to view 3D Blu-Ray content (not a demo disc, but a movie) on the screen.
Yes. LEDs use less power, use lower voltage, run cool and last longer. The white light is every bit as good as CCFLs.
Television technology is suffering from some confusing terms at present. LCD televisions use a light behind the liquid crystal panel. The light has been a cold cathode device… but recently, LEDs have been used as an alternative. Both use the same LCD imaging technology. A true LED television uses LEDs to generate red, green and blue light for every pixel. The technology has been with us for many years and is used extensively in large outdoor displays for concerts and stadia for example. Very recently, organic LEDs (OLEDs) have been used to create domestic sized displays. They offer the same high contrast capability of the larger displays and are a simpler construction than LCD models. The use of directly driven LEDs also allows a much faster update rate than LCD so they overcome any issues of image lag or smearing that can sometimes be noticed with LCD or plasma displays. The disadvantage is the current price. In 2012, OLED televisions are far more expensive than other technologies but expect the price to fall dramatically in the coming year or two as production volumes increase.
