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: A method and an apparatus for adjusting a brightness of a display are provided. The method includes: acquiring a gray scale number and a working frequency; determining a first gray scale compensation value of a preset calibration area using a preset gray scale compensation mapping table; determining a second gray scale compensation value of a non-preset calibration area according to the first gray scale compensation value; controlling, according to the first gray scale compensation value, the preset calibration area for displaying; and controlling, according to the second gray scale compensation value, the non-preset calibration area for displaying.
