Screen brightness adjustment method, electronic device, and computer-readable storage medium

A screen brightness adjustment method, applied to a first electronic device, wherein the method comprises:

• obtaining, by the first electronic device, control information corresponding to a to-be-displayed picture frame, wherein the to-be-displayed picture frame is a kth picture frame obtained after the first electronic device detects that dimming mode switching occurs, 1≤k≤M, k is a positive integer, and M is a preset positive integer;
• the control information corresponding to the to-be-displayed picture frame is used to indicate screen brightness of the first electronic device when the first electronic device displays the to-be-displayed picture frame;
• the screen brightness indicated by the control information corresponding to the to-be-displayed picture frame is lower than first screen ideal brightness;
• the first screen ideal brightness is a preset brightness threshold that triggers the first electronic device to perform the dimming mode switching;
• and the dimming mode switching comprises switching from a pulse width modulation PWM mode to a direct current DC mode or switching from the DC mode to the PWM mode;
• and
• when displaying the to-be-displayed picture frame, adjusting, by the first electronic device, screen brightness of the first electronic device to the screen brightness indicated by the control information corresponding to the to-be-displayed picture frame.
