Claim 8:
9. A method for adjusting display panel brightness, used to determine a voltage value of a control signal of the control signal terminal of the display panel according to claim 2, the method comprising:
setting the control signal of the control signal terminal to have an initial voltage value, and performing gamma debugging on the display panel to keep brightness consistency of the first display area and the second display area in white pictures at respective gray levels;
at the initial voltage value, displaying a monochrome picture of a first gray level on both the first display area and the second display area, and judging whether a brightness difference between the first display area and the second display area is within a first preset range;
under a condition that the brightness difference between the first display area and the second display area is beyond the first preset range, adjusting the initial voltage value to obtain a first voltage value, at which the brightness difference between the first display area and the second display area is within the first preset range; and
taking the first voltage value as the voltage value of the control signal of the control signal terminal when both the first display area and the second display area display the monochrome picture of the first gray level.
