Brightness compensation method for display panel and electronic device

An electronic device, wherein the electronic device comprises a display screen, a memory, and one or more processors;

• the display screen comprises a display panel;
• the display screen, the memory, and the processors are coupled;
• and the memory is configured to store computer program code, the computer program code comprises computer instructions, and when the computer instructions are executed by the electronic device, the electronic device is enabled to execute:
• when detecting that the display panel displays a to-be-displayed image at a current display brightness value, determining a brightness interval in which the current display brightness value is located, wherein difference information between mura images presented on the display panel at display brightness values in a same brightness interval is within a first preset difference range;
• determining gray level intervals corresponding to the brightness interval, wherein the gray level intervals corresponding to the brightness interval are determined based on gray level node values corresponding to the brightness interval, different brightness intervals correspond to different gray level node values, different gray level intervals correspond to different brightness compensation values, and the brightness compensation value is a difference between an actual brightness value of each pixel unit in the display panel in a corresponding gray level interval and a target brightness value;
• and
• obtaining a gray level of the to-be-displayed image, and compensating each pixel unit in the display panel based on a brightness compensation value corresponding to a gray level interval in which the gray level is located.

A computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions, and when the computer instructions are run on an electronic device, the electronic device is enabled to execute:

• when detecting that the display panel displays a to-be-displayed image at a current display brightness value, determining a brightness interval in which the current display brightness value is located, wherein difference information between mura images presented on the display panel at display brightness values in a same brightness interval is within a first preset difference range;
• determining gray level intervals corresponding to the brightness interval, wherein the gray level intervals corresponding to the brightness interval are determined based on gray level node values corresponding to the brightness interval, different brightness intervals correspond to different gray level node values, different gray level intervals correspond to different brightness compensation values, and the brightness compensation value is a difference between an actual brightness value of each pixel unit in the display panel in a corresponding gray level interval and a target brightness value;
• and
• obtaining a gray level of the to-be-displayed image, and compensating each pixel unit in the display panel based on a brightness compensation value corresponding to a gray level interval in which the gray level is located.
