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?
HDTV
All televisions of this type are illuminated by LEDs, which have been shown to give some advantages over other types of lightingLighting. they have illuminated LED TV, LED behind the screen that is similar to how an LCD television has made his light organized.
These LED lights are arranged in blocks and are so together that you can simultaneously control group. Therefore, each block the ability to turn on and off separately from the other blocks around him. The advantage of this is that in a picture with some dark areas and some areas of light, the dark parts of theirBlocks turned completely to allow a signal completely black.
Such monitoring is not possible on an LCD TV.
Local dimming technology
The name of this technique, local dimming, and this is the term that you should try if you have a TV LED that is created in this way want to buy. The main advantage is an HDTV of this type of LED technology to television may have a contrast ratio better than other types of high definition. LCDs are alwaysTraditionally had a problem with poor contrast compared to that of a plasma TV, and so this type of backlight, this problem started.
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 have the same problems with an LCD TV connected in the block can not be completely connected, and soyou can not completely obscure the black part.
Is there a way, this issue, and I have resolved a LED light for each pixel on the screen - but the problem is that it would be too expensive for the construction of a television in this way and that could be too expensive to buy for many people. with all things considered, however, this construction, an LED backlit HDTV usually means producing a TV with a better picture than most LCDTV.
Abstract LED HDTV
So we can see that there are actually more than one type of LED HDTV, you can buy and the way it is built you will have a greater impact on image quality, this is so if you buy a TV LED, it is important to understand the differences in design, they have a great impact on the performance of the TV.
HDTV LED illuminated from behind in a number of disadvantages compared with otherEdge-lit models - or LCD TV for that matter. You can read more about these topics by clicking the link below in the resource box.
