Viewing angle compensation method and apparatus for display panel, and display panel

Abstract

The present disclosure discloses a viewing angle compensation method and apparatus for a display panel, and the display panel, and relates to the technical field of liquid crystal displaying. The purpose of increasing a visual angle of an MVA liquid crystal panel can be achieved, and for a whitening phenomenon of a screen watched at a side viewing angle, a better improving effect can be given. A main technical solution of the present disclosure includes: receiving to-be-processed image data, the image data including pixel points formed in a plurality of rows and a plurality of columns, and each pixel point having different subpixels on red, green and blue three-color channels; adjusting current gray-scale values of the subpixels by looking up a preset visual compensation lookup table to obtain adjusted gray-scale values, the preset visual compensation lookup table including two corresponding gamma curves, and the two corresponding gamma curves being used for describing corresponding adjustable ranges of the gray-scale values; and acquiring first target image data as output target image data according to the adjusted gray-scale values corresponding to the subpixels.
