Compare LCD 3D LED Displays

Below are the differences between LCD TVs that are LED-backlit and LCD TVs that are conventionally CCFL-backlit:

a) The LED-backlit LCD TV is capable of producing images that have a more dynamic contrast as opposed to the images produced by CCFL-backlit LCD Television sets.

b) By making use of Edge-LED lighting, it can become very slim. There are now a lot of models available that may actually be less than an inch when it comes to the thickness.

c) When you have purchased this kind of TV you would be able to choose from a wider range of color gamut, particularly if the backlighting for RGB-LED is utilized.

d) The disposal on the pollution of the environment is less.

e) There would be an increase in the cost because of the placement of current products in the market.

More about Technology

There are manufacturers of Television sets who are now able to make utilize LED backlights as an alternative to the what was more commonly used LCD-CCFL, or the Cold Cathode Fluorescent Lamps. It should be taken into account that distinguishing the method used is very important as in the case of simply placing a backlight on the panel of the LCD, from that of placing real LED display as well as the OLED kind of display. Apart from this, it should also be taken note of that there is a difference between LED Television sets, which are based on LCD, and those that are based on display technologies like OLED, AMOLED, or OEL that is said to be self-illuminating. It was made clear in the United Kingdom, by the Advertising Standards Authority, or ASA, that the use of the words LED TV does not receive any objection from them, however, it is necessary to have things clarified whenever an advertising is made. It is possible to make use of different kinds of methods when it comes to placing a backlight onto the LCD panel with the use of LEDs and this includes using LED which may be White or even RGB that will be placed on the back part of the panel, an Edge-LED kind of lighting would also be used.

When the LED backlight is utilized, it would be seen that there are a lot of benefits that can be gained from it, compared to using the more common TVs that have CCFL backlight, which usually is having brightness that is higher over the other. With regard to color gamut, it may also be considered that there are benefits that could be gained as well as opposed to the backlighting with the CCFL.

Making use of the various kinds of the LED backlighting would also be able to provide different kinds of benefits. In 2004, the Sony Qualia 005 was released, and this is considered to be the very first kind of LCD TV that was built in with commercial LED backlighting. One of its features was that it had RGB LED which was able to provide a much better kind of color gamut compared to an LCD television that is equipped with CCFL. In this case, combination of the output of the blue, red as well as green LEDs made it possible to produce white light that is more pure. Up to now, the technology of RGB LED is still being utilized on certain models of the Sony Bravia LCD, with an added feature which allows the users to enable on-screen contrast that is truly remarkable.

In the month of September in 2008, the Edge LED kind of lighting was made known to the market by Sony through the release of the BRAVIA KLV-40ZX1M, and in Europe, it is called the ZX2. Primarily, the Edge-LED kind of lighting made it possible for LCD TVs to have housings that are thinner than usual, similar to the case of this 40-inch TV. Another company, Samsung, also came up with their own range that also had housings that are very thin, thanks to the Edge-LED backlighting given to the LCD TVs.

It is more advisable to opt for LCD TVs that have LED backlight because of the longer lifespan that it is capable of and at the same time, it is more energy efficient compared to other kinds of TVs like the plasmas or even other kinds of LCD TVs that are conventional.
