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

An electronic device, comprising:

• a display;
• a memory;
• and
• a processor, wherein the display and the memory are coupled to the processor;
• wherein the memory stores computer program code, the computer program code comprises computer instructions, and when the computer instructions are executed by the processor, the electronic device is enabled to perform operations comprising:
• obtaining 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 electronic device detects that dimming mode switching occurs, wherein 1≤k≤M, k is a positive integer, and M is a preset positive integer, wherein the control information corresponding to the to-be-displayed picture frame is used to indicate a screen brightness of the electronic device when the electronic device displays the to-be-displayed picture frame, wherein the screen brightness indicated by the control information corresponding to the to-be-displayed picture frame is lower than a first screen ideal brightness, wherein the first screen ideal brightness is a preset brightness threshold that triggers the electronic device to perform the dimming mode switching, and wherein 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 on the display, adjusting screen brightness of the electronic device to the screen brightness indicated by the control information corresponding to the to-be-displayed picture frame;
• wherein the obtaining the control information corresponding to the to-be-displayed picture frame comprises:
• obtaining the control information corresponding to the to-be-displayed picture frame from M pre-stored screen brightness parameters, wherein each screen brightness parameter of the M pre-stored screen brightness parameters comprises control information corresponding to one picture frame, and the to-be-displayed picture frame is a picture frame in the M screen brightness parameters;
• wherein the control information is obtained by calculating a second screen ideal brightness and a second screen actual brightness of a second electronic device when the dimming mode switching occurs, the second screen ideal brightness is a preset brightness threshold that triggers the second electronic device to perform the dimming mode switching, and the second screen actual brightness is an actual brightness value obtained when the second electronic device displays the picture frame;
• and
• wherein the screen brightness indicated by the control information in each screen brightness parameter of the M pre-stored screen brightness parameters is obtained based on a difference between the second screen ideal brightness and a second screen jump brightness, and the second screen jump brightness is a difference between the second screen actual brightness and the second screen ideal brightness.

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, wherein 1≤k≤M, k is a positive integer, and M is a preset positive integer, wherein the control information corresponding to the to-be-displayed picture frame is used to indicate a screen brightness of the first electronic device when the first electronic device displays the to-be-displayed picture frame, wherein the screen brightness indicated by the control information corresponding to the to-be-displayed picture frame is lower than a first screen ideal brightness, wherein the first screen ideal brightness is a preset brightness threshold that triggers the first electronic device to perform the dimming mode switching, and wherein 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, the screen brightness of the first electronic device to the screen brightness indicated by the control information corresponding to the to-be-displayed picture frame;
• wherein the obtaining the control information corresponding to the to-be-displayed picture frame comprises:
• obtaining the control information corresponding to the to-be-displayed picture frame from M pre-stored screen brightness parameters, wherein each screen brightness parameter of the M pre-stored screen brightness parameters comprises control information corresponding to one picture frame, and the to-be-displayed picture frame is a picture frame in the M screen brightness parameters;
• wherein the M pre-stored screen brightness parameters are one group of a plurality of groups of screen brightness parameters, and one group of the screen brightness parameters corresponds to one screen refresh rate;
• and
• wherein the M pre-stored screen brightness parameters are a group of screen brightness parameters corresponding to a current screen refresh rate of the first electronic device.
