Under normal circumstances, the three color combinations of red, green and blue should satisfy the light intensity ratio tending to 3:6:1; red imaging sensitivity is stronger, so the red in the space display must be evenly distributed; because the light intensity of the three colors is different, The resolution nonlinear curve presented by people's visual experience is also different, so we need to use white light with different light intensities to correct the internal light of the TV; the color resolution ability is different due to personal differences and environmental differences, and color reproduction needs to be performed according to certain objective indicators
(1) Position the basic wavelength of 660nm red light, 525nm green light, and 470nm blue light.
(2) Outdoor LED display screens are matched with 4 tubes or more white light units according to the actual conditions of light intensity.
(3) The gray scale is 256 levels.
(4) LED pixels must be processed with non-linear proofreading. The three-color piping can be controlled by the cooperation of the hardware system and the playback system software.
