1. A method for view angle compensation, comprising:
obtaining initial pixel data of a to-be-displayed image;
obtaining pixel data corresponding to any two adjacent initial pixels in the initial pixel data;
determining a grayscale difference between the two adjacent initial pixels;
in response to determining that the grayscale difference is greater than a preset grayscale difference, determining the pixel data corresponding to the two adjacent initial pixels as target pixel data;
determining a region in which a plurality of target pixels corresponding to the target pixel data are located as the target pixel region;
pre-processing the initial pixel data to obtain intermediate pixel data;
determining to-be-compensated pixel data in the intermediate pixel data based on the target pixel region; and
performing a view angle compensation on the to-be-compensated pixel data in the intermediate pixel data to obtain display pixel data.
