Generally speaking, the combination of red, green and blue should meet the light intensity ratio of 3:6:1; The red imaging sensitivity is stronger, so the red in the spatial display must be evenly distributed; Due to the different light intensity of the three colors, people's visual perception presents different non-linear resolution curves. Therefore, it is necessary to use white light with different light intensity to correct the internal light emitted by the TV.
Color resolution varies with individual differences and environmental differences, and color restoration needs to be carried out according to certain objective indicators, such as:
(1) The 660nm red light, 525nm green light and 470nm blue light are positioned as the fundamental wave.
(2) According to the actual light intensity, 4 or more white light units are used for matching.
(3) The gray level is 256.
(4) LED pixels must be non-linear calibrated. Tri color edging can be controlled through the cooperation of hardware system and playback system software.
