Why use LED as the backlight of LCD TV?

The main purpose of using LED as the backlight source of LCD TVs is to improve the picture quality, especially in terms of color saturation. The display screen of LED backlight technology can achieve a wide enough color gamut to make up for the defect of insufficient display colors of LCD devices. It can meet or exceed the requirements of Adobe RGB and NTSC color standards, and can reach NTSC ratio of more than 100%. Among them, Sony has introduced LCD TV panels with LED backlights, with special emphasis on bright red and dark green performance, which can display more lifelike than previous methods. s color.

At the same time, because of the flat light source characteristics of the LED, the LED backlight can also realize the sub-regional color and chromaticity adjustment function that CCFL cannot match, so as to achieve more accurate color reproduction to meet the needs of graphic publishing and graphic design work. The dynamic adjustment of can make the brightness and contrast can be dynamically corrected when different pictures are displayed, in order to achieve better picture quality.

Because of its unique advantages such as energy saving, environmental protection, long life, safety, fast response, small size, rich color, and controllability, LED light source is considered to be the best way to achieve energy saving and energy saving.
