Abstract

The invention relates to a color correction method and device. The method includes obtaining the first chromaticity correction coefficient of each LED light point in an LED display screen, and obtaining the first chromaticity correction coefficient of each IC in each LED module according to a preset calculation strategy for inter-block difference compensation value. The compensation value of each block; use the compensation value of each IC block to compensate the first chromaticity correction coefficient corresponding to each IC block, and obtain the second chromaticity correction coefficient of each LED light point in the LED display screen; obtain The brightness correction coefficient of each LED light point in the LED display, according to the preset brightness and chromaticity fusion strategy, fuses the brightness correction coefficient corresponding to each LED light point in the LED display with the second chromaticity correction coefficient to obtain the brightness and chromaticity correction Coefficient; send the brightness and chromaticity correction coefficient to the LED display. The method and device provided by the invention can effectively improve the chromaticity uniformity of the LED display screen and improve the correction effect.

Description

technical field [0001] The present invention relates to the field of display screen calibration, in particular to a color correction calibration method, device and computer equipment. Background technique [0002] In the existing technology, it is necessary to perform color correction correction on the COB (Chips on Board, a new display packaging technology) display screen. In the actual measurement process of color correction correction, there will be two main chromaticity deviations , First, when the display screen is calibrated by blocks, the difference between each block is much higher than the difference within the block. When correcting, the actual compensation value is always unable to ideally eliminate the difference between the blocks; the second is In chromaticity correction, due to the systematic error caused by the ideal model of chromaticity correction, the chromaticity uniformity decreases, especially the chromaticity uniformity of the blue channel in the monoc...
