LED backlight module production need to build a unified standard standards

Control LED backlight is more flexible than CCFL color, brightness and other indicators are also different. The development of LED technology at the same time, the type of LED tends to be diversified, manufacturers of LED scale, for the LED detection equipment is different, this phenomenon may lead to LED quality and life are not unified, ultimately with the same type of different manufacturers LED showed inconsistent product performance.

Stage, direct type RGB-LED backlight technology should be said is not mature, there are still some unresolved problems being solved or. Such as the use of a large number of independent LED devices, lattice arrangement is quite dense, and various research institutions are committed to LED and mixed control technology, and strive to reduce the backlight of LED and the requirement to reduce the cost, improve the uniformity of luminous efficiency; RGB-LED backlight is a little weaker. Although the high color purity of RGB-LED, but each LED color decay after long-term use rate is not consistent, it will also have a greater impact on image quality, many are working on LED compensation algorithm of color decay, but do not have a unified and reasonable standard to assess.

Along with the development of liquid crystal industry to replace the LED backlight CCFL backlight is becoming more and more mature, we should construct LED backlight display specification based on the specification of display products based on the standard LED, the specification of various LED control technology assessment standards.

To sum up, the development of LED backlight technology relates to LED chip preparation, mechanical processing, digital image processing technology, taking into account the dynamic market demand TFT-LCD. From time to time, LED backlight module technology will go through several stages of development, LED backlight alternative CCFL backlight stage, LED backlight technology maturity stage, LED backlight with the overall development of the TFT-LCD.

LED backlit LCD display is closely related to the technical parameters of important parameters such as brightness, color gamut, module power, volume, quality, and cost of the backlight, and even some indicators directly depends on the parameters of LED backlight. These parameters are LED liquid crystal display stand display field is fundamental, and other display methods such as PDP, OLED etc. the technology competitive advantage, is the industry's huge investment security. Only these parameters have a strong competitiveness, huge investment in LCD production line is more vitality.
