Hdtv
All televisions of this type are illuminated by LEDs, which have shown some advantages over other types of lighting to give. Backlit LED TVhave LED lights behind the screen, similar to how an LCD television has its own lighting is organized.
These LED lamps are set into blocks and they are together, so that will be checked at the same time can be grouped. Therefore, each block can be separated off and on, has for the other blocks around him. The advantage of this is that in a photo with some dark areas and some areas of light, the dark portions can be fully activated blocksallow a completely black signal.
This additional control is not possible on an LCD TV.
Local dimming
The name of this technique, local dimming, and this is the term that you should try if you have a TV LED that is constructed in this way want to buy. The main advantage is an HDTV with this type of LED technology can have a contrast ratio better than other types of high-definition television. LCDs have traditionally been a problem with a poor contrast ratiocompared to that of a plasma TV, and so this type of backlight to the solution of this problem.
The problems with local dimming
As always with all this technology there is a downside to this idea. Problems occur when a block of lights is covered by a light and dark part of the image. These have the same problem with an LCD-TV, where the lock goes out completely connected, so it is completely impossible to get the blackdark.
Is there a way to solve this problem, and that would be an LED light for each pixel on the screen have – but the problem is that it would be too expensive to build a TV in this way and so would buy too expensive for many people. But all things considered, this construction, an LED-backlit HDTV is a television with generally produce a better picture than most LCD TVs.
