Abstract:
A brightness compensation method, apparatus and device (400) for a display panel (100). The display panel (100) has a first display region (AA1) and a second display region (AA2). The brightness compensation method comprises: selecting, from the second display region (AA2), at least one first region (Q1) close to the first display region (AA1) (201); acquiring the current brightness value of a sub-pixel in each first region (Q1) at a target grayscale value (202); determining an average brightness value of the at least one first region (Q1) on the basis of the current brightness value of the sub-pixel in each first region (Q1) (203); determining a target brightness value of the first display region (AA1) at the target grayscale value according to the average brightness value (204); and performing brightness compensation on the first display region (AA1) on the basis of the target brightness value (205). The brightness compensation method can improve the brightness consistency of the display panel (100).
