Abstract: The application provides a display device and a display charging method. The display device includes a timing controller and a gate driving circuit. By increasing a voltage difference between the first potential and the second potential of a scan signal, a falling edge of the scan signal can be made more vertical, and by adjusting a phase of the scan signal in a timing at the same time, a pulse duration of the scan signal can be overlaid to a pulse duration of more data signals, so that the effective charging time of the data signals can be increased.

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.
