The new SHARP LE700A series LED TV uses straight LED Bai Guangyuan

The application of LED technology in the field of liquid crystal, mainly using LED CCFL fluorescent light emitting element instead of, as the liquid crystal display backlight device, in accordance with the color light emitted from the LED, divided into white LED backlight and backlight RGB-LED two.

From the SHARP LE700A series LED TV, as the location is relatively low category of products, SHARP LE700A series is used directly in type LED white light source. The use of white LED can effectively reduce the thickness of the liquid crystal panel, the realization of ultra-thin products.

Straight type LED white light source, light source color is given in the LED, the back light is white, a liquid crystal layer, and then through the R/G/B color filter film, become independent color. In this process, the key to determine the color of liquid crystal display device is not the liquid crystal layer, but the quality of the backlight. Backlight source in the spectrum of RGB the purity of each of the original color of the higher, in order to restore the more pure primary colors, only to restore the pure RGB primary colors, in order to deploy a pure and true color effects.

Compared with white light, RGB-LED backlight backlight is more prominent, RGB-LED backlight is LED elements emit high purity by red, green and blue light can be realized, the traditional CCFL light source can not achieve the broad color gamut. At present, the mainstream RGB-LED backlight can reach 105% of the NTSC color gamut, and as long as the use of more powerful LED devices, has been able to achieve more than 120% of the NTSC color gamut. However, the use of RGB-LED backlight high cost, the price is quite expensive. Before the launch of the SHARP XS1 series LED TV products, the use of RGB-LED backlight.

Whether it is white light or RGB-LED light, compared with the conventional CCFL backlight system, it has the advantages of quite prominent, such as screen contrast, can be increased to a very high standard, with black color performance bright image and the There was no parallel in history. incredible, showing a picture of telepresence.
