1. A display compensation method for a display panel, comprising:
selecting a plurality of first compensation data tables for a first to-be-compensated sub-pixel set in a first viewing angle, as a first target compensation data set, and selecting a plurality of second compensation data tables for a second to-be-compensated sub-pixel set in a second viewing angle, as a second target compensation data set; wherein the first to-be-compensated sub-pixel set is adjacent to the second to-be-compensated sub-pixel set, and the first viewing angle is different from the second viewing angle; and
generating a first target compensation value based on the first target compensation data set to compensate for a first display luminance of a first sub-pixel to be compensated comprised in the first to-be-compensated sub-pixel set; generating a second target compensation value based on the second target compensation data set to compensate for a second display luminance of a second sub-pixel to be compensated comprised in the second to-be-compensated sub-pixel set,
wherein the first and second viewing angles refer to angles of viewing directions from different positions of a user with respect to a normal line of the display panel perpendicular to a surface of the display panel at a center of the display panel.
