National debut: BOE display tricolor mixed LED backlight

Is being held in the tenth circle of Cobo, BOE optoelectronics showcased LED LCD backlight newly developed, it is reported that this is the first domestic manufacturers to launch this product. According to the site of the BOE engineers said that this display backlight system and many manufacturers to promote the so-called "white LED" backlight has the distinction, it integrates hundreds of lighting units, each unit contains a total of 4 RGB LED, in order to increase the brightness of the green, two led the integration, finally by RGB mixed colors are pure white. Compared with the ordinary white LED, the white light is more pure, and the brightness is high, which can significantly improve the NTSC color gamut of the display. The liquid crystal display using the backlight system, the color reduction can be almost and CRT contend. The reporter asked what time this monitor can officially put on the market, the BOE staff said there is no such plan, the reason is that the LED backlight cost is very high, the production technology also needs to be further improved. In addition, the current LED backlight larger heat, the need to further solve the problem of heat dissipation. The liquid crystal display is transmissive display device, the internal need to have a strong light source to correctly display the image, the traditional liquid crystal display using CCFL cold light source as a light emitting device, it is not pure white, uneven light, large volume and high energy consumption itself is relatively fragile. The LED can basically overcome the shortcomings of CCFL, and compact size, longer service life, especially white light, can greatly improve the performance of color display. Currently the biggest obstacle to limit the popularity of LED is the price, the size of the LED light source is much higher than the traditional CCFL light source. Although there are some shortcomings, but the industry believes that LED is the future direction of the development of liquid crystal display, which is beyond doubt.
