LED HDTV - Understanding the different types of LED TV

There are two main types of LED HDTV, and can be divided into two different versions of the type of backlight. This is called an edge lit LED and the other is known as a TV with LED backlight. In this article we will look at the LED-backlit HDTV and trying to understand how it works.

What is an illuminated LED HDTV back?

All televisions of this type are illuminated by some LED lamps have been found to giveAdvantages over other types of lighting. Backlit LED TV LED ordered placed directly behind the screen, the TV is similar to how an LCD has its own light.

These LED lights are arranged in blocks, and are grouped in chronological order, so that controls can be the same. Therefore, each block the ability to turn on and off separately from the other blocks around him. The advantage is that with an image in somedark areas and some areas of light, the dark areas have turned off their blocks to trigger an all black finish.

This control is not possible to watch TV on an LCD.

Local dimming technology

The name of this technique, local dimming, and this is the term you are looking for should, if you will, that buying a TV that is mounted LED. The main advantage is an HDTV with this type of LED technology can improveContrast ratio compared to other types of high-definition television. LCD monitors have traditionally always had a problem with poor contrast compared to that of a plasma TV, and so this kind of background lighting of the problem is at this address.

The problems with local dimming

As always with all this technology there is a downside to this idea. The problems occur when a block of lights is covered by a light and a dark part of the picture. These havesame problems found in a dark LCD TV, in which the block can not be fully open, and therefore it is impossible for the black completely.

It 's a way to solve this problem for the screen and the TV would be to have an LED light for each pixel - but the problem is that it would be too expensive to build, to a TV and in this way would be to buy, are too expensive for most people. But for pure things considered,this construction, an LED backlit HDTV usually means producing a TV with a better picture than most LCD TVs.

Abstract LED HDTV

So we can see that there are actually more than one type of LED HDTV, you can buy, and how it is built will have a major impact on image quality, this way when watching TV to buy a LED clock then it is important to understand the differences in designbecause they have a great influence on the performance of the TV.

HDTV LED backlight, a couple of disadvantages compared to the models of the Edge-lit - LCD TV or for that matter. You can read more about these topics by clicking the link below in the resource box.
