About LED Tvtechnology

The light releasing display television or the LED TV is one of the newest television craze. Firms have been boasting of the different benefits of having an LED TV including its echo friendly feature. Companies like Vizio, ProScan, LG Electronics, Samsung Electronics, Panasonic, Toshiba and Philips are supplying the complicated feature of echo friendly LED television. For the benefit of those that doesn't know, the LED television is the liquid-crystal display TV or the LCD TV that utilises LED backlighting instead of the common cold cathode fluorescent lights the LCD television is using.

You are perhaps considering why they're using the LED light and not just exploited the normal cold cathode fluorescent light or CCF light. It's usually because the LED backlit can produce photos with wonderful dynamic contrast compared to the fluorescent light. The TV screen is much slim due to the edge-LED lighting. A wider colour scope is 1 explanation why LED lighting is preferred than the common fluorescent lighting particular ly when RGB-LED back lighting is used.

Sony Qualia 005 was the very first LED television introduced in the year 2004 and this feature the RGB LED arrays that offer twice resolution than the Cold Cathode Fluorescent Light LCD television. Red Green and Blue LEDS produce a better light output of pure white that the single white light LED. Selected Sony Bravia LCD TV uses the RGB LED technology with the extra feature of local dimming that permits a better on-screen contrast.

Sony also introduced the 1st Edge LED TV Technology on the Sep of 2008 and it is a forty inch BRAVIA KLV-40ZX1M. The important benefit of the Edge LED television is its thin housing and the 1st Edge television is as thin as 9.9 mm. Intensely thin housing Edge LED television are introduced by Samsung.

The LED television displays a more high-res because LED can be switched off and on more quickly than the fluorescent lighting. This is also why LED TV offers a high ratio contrast. Though LED television offers deep black and high lightness image care should be taken with measurements of pure white and pure black output because Edge-LED lighting doesn't allow reproduction of this colour at the same time.

Just last September 2009 Nanoco Group together with major Japanes Electronics Company has made public that they will develop a new LED technology that would enhance the demonstration of the LED TV. The quantum dot is the third LED technology along with Edge LED and RGB LED. The quantum dots emit light with a particular gaussuian distribution making the display excellent for it accurately delivers the colours that our naked eye can perceive. This new LED TV Technology requires a little power because it's not colour filtered.
