A gray scale compensation method for a display panel includes: dividing a display region of the display panel into a first display region, a second display region and a transition display region arranged between the first and second display regions; configuring a first compensation algorithm for the first display region to obtain a first compensation gray scale of the first display region, configuring, for the second display region, a second compensation algorithm different from the first compensation algorithm to obtain a second compensation gray scale of the second display region, and configuring, for the transition display region, a third compensation algorithm different from the first and second compensation algorithms to obtain a third compensation gray scale of the transition display region; and configuring the display panel to display an image according to the first compensation gray scale, the second compensation gray scale and the third compensation gray scale.

Gray scale compensation method and apparatus for display panel

A method includes: dividing a display area of a display panel into multiple sub-display areas distributed in an array; selecting at least two sub-display areas as reference sub-display areas, the reference sub-display areas being adjacent and one reference sub-display area includes a target sub-pixel to be compensated; determining a weight factor for each reference sub-display area according to a distance between a center point of the target sub-pixel and a center point of the reference sub-display area and a distance between center points of adjacent reference sub-display areas; calculating a weighted sum of average luminance values of the reference sub-display areas under a target grayscale value with the weight factors for the reference sub-display areas to obtain a target luminance value of the target sub-pixel under the target grayscale value; determining a compensation grayscale value of the target sub-pixel under the target grayscale value according to the target luminance value.
