Abstract: The present disclosure relates to a brightness matching method of a display and the display. The method includes: performing first calibration on a brightness of at least one second display panel according to first calibration information to obtain a first calibration brightness; performing second calibration on the brightness of the at least one second display panel according to second calibration information to obtain a second calibration brightness; and performing third calibration on the brightness of the at least one second display panel according to the first calibration brightness and the second calibration brightness to obtain a third calibration brightness to match the brightness of the at least one second display panel with a brightness of at least one first display panel.

Abstract: A compensation method of a display panel includes controlling a first display part of a target panel to display a light load image based on a standard gamma curve, controlling a second display part of the target panel to display a heavy load image, acquiring a first brightness of a first color sub-pixels in an (N1+1)th row electrically connected to a first data line of the first display part, acquiring a second brightness of the first color sub-pixels in an (N2+1)th row of a first sub-display part of the second display part electrically connected to a second data line, and according to a difference between the first brightness and the second brightness, determining a first compensation data corresponding to the first gray scale and the second preset gray scale of at least the first color sub-pixels of the first sub-display part in the target panel.
