Correction method and device of four-color lamp bead LED display box and electronic equipment

The invention belongs to the technical field of LED display, and particularly relates to a correction method and device for a four-color lamp bead LED display box and electronic equipment. The method comprises the following steps: acquiring point-by-point chroma correction data; processing the point-by-point chromaticity correction data; calculating tristimulus values and correction coefficients of the point-by-point four-color lamp beads; and carrying out point-by-point correction on the four-color lamp beads. The step of acquiring the point-by-point chromaticity correction data comprises the following steps of: determining a correction target color space; acquiring color parameters of four-color lamp beads; performing first correction to obtain a correction coefficient C0; and performing second correction to obtain a correction coefficient C1. After the lamp panel with the four-color lamp beads is corrected through the method, the color consistency of all pixels on the lamp panel is greatly improved. 本发明属于L
