Upstream and downstream firms have invested in LCD LED Factory, the main purpose is not to obtain the LED backlighting technology capacity but rather to consider technology. Technically the LED package, the wavelength of light, the light will affect the angle of the backlight module, panel makers and backlight module plant require relatively close relationship of the LED manufacturers with special products for various experiments and reliability tests. In addition, panel makers and backlight module plant has faced the problem of shortage of CCFL to master the material source to become the subject of panel makers and backlight module plant investment LED plant in order to prevent shortages in LED large-scale use concerns, rather than focusing on short-term interests.
LED backlighting technology for LCD TV, the main objective is to enhance the quality, color saturation, LED backlight display can be made wide enough color gamut, make up the LCD device to display color insufficient number of defects, so that can reach or even exceed the requirements of the Adobe RGB and NTSC color standards, and can reach 100% or more of the NTSC ratio, which Sony introduced LED-backlit LCD TV panels, with particular emphasis on red and dark green performance, can display more realistic than the previous waycolor. LED high bay light source characteristics, so that the LED backlight can achieve the CCFL can not be compared regulatory function and the sub-region color and chroma, in order to achieve more accurate color reproduction, and to adapt to the needs of the print publishing and graphic design work, the picture dynamic adjustments can make a different screen is displayed, the brightness and contrast can be dynamically amended so as to achieve better picture quality
