In general, the combination of red, green and blue colors should meet the light sensitivity intensity ratio tends to 3:6:1; Red imaging is more sensitive, so the red color in the spatial display must be evenly distributed. Because three kinds of color light intensity is different, people's visual perception of the resolution of nonlinear curve is also different, so we should benefit different light intensity white light, correct the TV internal light; Color discrimination ability is different due to personal differences and environmental differences, and color reproduction should be carried out according to certain objective indicators, such as:
(1) Position the basic wavelength of 660nm red light, 525nm green light and 470nm blue light.
(2) According to the actual situation of light intensity, use 4 tubes or more than 4 tubes of white light unit for matching.
(3) The gray level is 256 levels.
(4) LED pixels must be processed with nonlinear proofreading. The three primary color piping can be controlled by the hardware system and the playback system software
