About the LED TV
There are different kinds of TVs and LED TV is now one of the ruling options. There are however still some confusions surrounding what exactly an LED TV is. Basically LED television has an LCD screen that uses LED backlight to provide its source light.
All LCD televisions are using backlights because liquid crystal displays are a transmissive type of display technology meaning they do not create their own light. For an LCD TV to produce an image on a flat panel screen, its pixels have to be backlit by a separate source of light. Most LCD televisions use cold cathode fluorescent lamps as their backlight source. They give good colors and brightness with a decent contrast but are not great at black colors. By utilizing brighter LED backlighting you can attain better black color and even greater contrast. There are a couple of led options; these are the full matrix and Edge Lit LED television.
A true LED television is one of those giant screens you see at the outdoor coliseums, grand pix, and rock avenues. These are large screens that are made up of thousands of extremely bright LED lights. LED are the best sources for backlighting LCD screens.
Edge lighting is from the word itself “edge”, the LED lights are put at the edge of the screens to produce lights. From there, the light is scattered around the screen, which means the LED LCD television can be produced thick or can be made very thin. The results are better than CCFL screens. The black levels using edge lighting are not so deep, the edge of the screens are brighter compared to the middle screen.
Full array backlighting uses many rows of LED placed behind the entire surface of the screen or display. It is a bit thicker compared to Edge lighting. The LED provides even, brighter color and greater contrast. Using full array of backlighting offers better quality picture on LED TV.
