Abstract

The invention discloses a chromaticity compensation method, a chromaticity compensation device and a computer-readable medium. The chromaticity compensation method divides a display area into a plurality of closely arranged sub-display areas, according to preset standard chromaticity values ​​and The measured chromaticity value corresponding to each sub-display area is determined, and the corresponding chromaticity compensation value of each sub-display area is determined; by smoothing the chromaticity compensation value corresponding to each sub-display area, each sub-display area in each sub-display area is determined. The chromaticity compensation value after the pixel smoothing process is used to perform chromaticity compensation on each sub-pixel during display, so as to realize targeted sub-pixels at different positions in the display area. Chroma compensation, reducing the chromaticity difference of the display screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a chromaticity compensation method, a chromaticity compensation device and a computer-readable medium. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements on the display quality of the display panel, and the uneven chromaticity of the display panel will have a great impact on the display quality of the display panel. [0003] In the related art, the central area of ​​the display panel is selected as a reference point, the chromaticity compensation value of the central area is measured, and the chromaticity compensation is performed on the sub-pixels in the entire display panel according to the chromaticity compensation value of the central area. However, in the process of manufacturing the display panel, due to technological reasons, the film layer cannot be guaranteed to be evenly distributed, which wil...
