Abstract: A method for adjusting grayscales of a display panel and a display panel, wherein firstly obtaining a reference brightness corresponding to each original grayscale according to each original grayscale, then filtering an initial dataset to obtain a preliminary dataset, calculating a weight of a preset brightness according to a front-viewing weight and the reference brightness, and finally selecting a group of grayscale data corresponding to the preset brightness with the smallest weight as a target high grayscale and a target low grayscale. The present disclosure can increase visual angles of the display panel and solve visual angle defects.

Abstract: A method for view angle compensation, includes: obtaining initial pixel data of a to-be-displayed image; performing a region detection on the initial pixel data to obtain a target pixel region in which a target pixel corresponding to target pixel data in the initial pixel data is located; 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.
