Abstract

Provided is a method for color correction of a tiled display device. The method comprises steps: determining respectively R, G, and B original target tristimulus values according to R, G, and B original target color coordinates and original target brightness prestored in the tiled display device; determining respectively R, G, and B target tristimulus values according to R, G, and B original target color coordinates and original target brightness of each display unit prestored in the tiled display device; determining respectively proportionality coefficients of variation of the R, G, and B tristimulus values according to the R, G, and B original target tristimulus values and target tristimulus values; determining respectively relative values of the R, G, and B tristimulus values of each display unit according to each proportionality coefficient and relative values of the R, G, and B original tristimulus values prestored in each display unit; and performing consistency calibration on colors of the tiled display device according to the relative value of each R, G, and B tristimulus value. The invention provides a corresponding system which improves calibration efficiency of each display unit of the tiled display device.

Description

technical field [0001] The present invention relates to the technical field of splicing display, in particular to a method and system for color correction of a splicing display device. Background technique [0002] Consistency calibration of the splicing display device is an important indicator of the quality of the display effect of the splicing display device, so it is necessary to perform consistency calibration on each display unit of the splicing display device. [0003] At present, each display unit of the spliced ​​display device is debugged separately according to the given original target color coordinates and original target brightness before building the spliced ​​display device. Because it is impossible to know which display units will be used in the same video wall, the given original target color coordinates and original target brightness are obtained through statistics, so the given original target color coordinates and original target brightness are not neces...
