Abstract: A method, apparatus, device, and storage medium for driving a display screen to display. The method includes: obtaining a current level of brightness adjustment of the display screen; obtaining, under a condition that the current level satisfies a first preset condition, an initial data voltage value and a compensation data voltage value corresponding to the current level, in which the first preset condition includes that a power voltage value corresponding to the current level is different from a power voltage value corresponding to a previous level or a next level directly adjacent to the current level, the current level is a level other than a designated level; and driving the display screen to display based on the initial data voltage value and the compensation data voltage value.

Abstract: A method for gamma debugging, an apparatus for gamma debugging and a device for gamma debugging. The method includes: acquiring a first voltage difference value between a first gray scale binding point and a second gray scale binding point of a first display panel at a first brightness level; performing gamma debugging on a second display panel at the first brightness level, to determine a voltage value corresponding to the first gray scale binding point of the second display panel at the first brightness level; and taking a difference between the voltage value corresponding to the first gray scale binding point of the second display panel at the first brightness level and the first voltage difference value as a first initial voltage value, to perform gamma debugging on the second display panel at the second gray scale binding point at the first brightness level.
