Claim 9:
10. The method for adjusting display panel brightness according to claim 9, wherein the method further comprises:
at the initial voltage value, displaying the monochrome picture of the first gray level on the second display area and a monochrome picture of a second gray level on the first display area, and judging whether a difference between a brightness value of the first display area and a target brightness value is within a second preset range;
under a condition that the difference between the brightness value of the first display area and the target brightness value is beyond the second preset range, adjusting the initial voltage value to obtain a second voltage value, at which a difference between a measured brightness value of the first display area and the target brightness value is within the second preset range; and
taking the second voltage value as the voltage value of the control signal of the control signal terminal when the second display area displays the monochrome picture of the first gray level and the first display area displays the monochrome picture of the second gray level.
