1. A method for brightness compensation of a display panel, the display panel having a first display region and a second display region, the method comprising:
selecting at least one first region in the second display region close to the first display region;
obtaining current brightness values of sub-pixels in the at least one first region under a target grayscale value by:
obtaining overall brightness data of an entire display region of the display panel;
selecting the current brightness values of the sub-pixels in the at least one first region under the target grayscale value from the overall brightness data;
determining an average brightness value of the at least one first region based on the current brightness values of the sub-pixels in the at least one first region;
determining a target brightness value of the first display region under the target grayscale value according to the average brightness value;
performing brightness compensation on the first display region based on the target brightness value.
