LED TV is also known as the light emitting diode television. It’s major difference is not about the quality of sound, it’s features or price. The beauty of LED TV stems from the backlights that are being used in the television and the enhanced quality of picture that results from their usage. A lot of people are mistaken in their understanding of what an LED television actually is. LED television is one of the newest and trendiest televisions already on the market. This is the future generation of televisions.
The LED TV and the LCD TV are almost the same but differ only in one thing, the backlight system that is being used. A Liquid Crystal Display television more commonly known as LCD TV creates an image through the pixels and a fluorescent backlight. LED television utilizes an LED backlight system to create a high quality images. There are two types of backlight systems being used in the LED television. These are the full array backlight system and the edge lighting backlight system.
Here are detailed explanations of these backlight systems and how they are useful in LED television:
Edge lightning is one of the backlighting systems used in LED television. From the word “edge” it can be deduced that the LEDs are placed on the outside edges of the television. The light produced is deflected and creates a scattered image of light all throughout the screen. Using the edge lighting system has its disadvantages and advantages. The advantage of using an edge lighting system is that the televisions can be made very thin and light weight.
The slimness of edge lit LED TVs makes them easy to wall mount but the disadvantage is they are not capable of producing very dark black images.
Another type of backlighting system is the full array. With a full array backlighting system, the LEDs are placed in a matrix to the rear of the screen. They can have a feature called local dimming in which the lights automatically go on and off to give control to the brightness and the darkness of the image on screen. Rear lighting produces the better quality images of these two variants of LED TV.
