Led Display Pixel
Dec 02, 2020
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 in people's visual experience is also different, so we must use different light intensities to correct the internal light of the TV; the color resolution ability of the LED display screen is different due to individual 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) According to the actual situation of light intensity, use 4 tubes or more than 4 white light units for matching.
(3) The gray scale is 256 levels. [4]
(4) The pixels of the led display screen must be processed by non-linear calibration. The three-color piping can be controlled by the cooperation of the hardware system and the playback system software.
