LED color processing technology from the most basic base color wavelength selection, to the white field color temperature deployment, and then to improve the degree of color reproduction and color space transformation processing and to improve the quality of the color uniformity of the processing until Today we are in order to expand the color gamut to reproduce more natural colors and take the multi-color processing. Here, we will introduce the full color of LED color processing technology.
First, LED full color display Screen color adjustment technology:
LED full color LED tube wavelength dispersion caused by the color of each pixel is caused by LED full color consistency is an important aspect of poor, so in the full color LED debugging process is necessary to adjust the white balance of the screen, we know Due to the reasons for the manufacture of LED die, the wavelength is exactly the same two LED is impossible to exist, LED light-emitting diode in the production has become an inherent physical characteristics, can not be in the subsequent production process to change the wavelength adjustment The
Second, LED full color electronic screen color processing technology:
1, in improving the color saturation at the same time, not change the color tone.
2, increase the yellow and green two primary colors in order to expand the color gamut, thereby improving the color saturation. While the overall brightness value can not be changed.
3, to D65 as the center; RYGCB color gamut as the endpoint, in the color gamut within the scope of linear expansion. Under the guidance of the above three principles; according to the law of gravity center, we can find 3 +2 multi-color chroma processing method. However, in order to truly achieve 3 +2 multi-color full color, we have to overcome the yellow, blue LED brightness is insufficient; cost increases and other difficulties, is currently limited to theoretical discussion.
People on the LED full color requirements are getting higher and higher, only the LED color coordinates of the subdivision and screening has been unable to meet people picky eyes, the display screen for comprehensive correction, so that chroma uniformity is improved can be achieved.
