Abstract
One or more embodiments of the present application disclose a backlight source control method of a display device, the display device and a storage medium, The method includes: determining a display subregion corresponding to a backlight source to be turned off; determining a first backlight source brightness value of an adjacent display subregion of the display subregion corresponding to the backlight source to be turned off; lowering the first backlight source brightness value to obtain a second backlight source brightness value; and setting the backlight source brightness value corresponding to the adjacent display subregion to be the second backlight source brightness value.
Claims18
A backlight source control method of a display device, comprising:
- obtaining an image to be displayed;
- determining a first backlight source brightness value of a first display subregion of the image corresponding to gray-scale values of pixels in the first display subregion, and a second backlight source brightness value of a second display subregion of the image corresponding to gray-scale values of pixels in the second display subregion, wherein a second backlight subregion corresponding to the second display subregion is adjacent to a first backlight subregion corresponding to the first display subregion;
- in response to a first backlight source in the first backlight subregion to be turned off based on the first backlight source brightness value, determining an adjusted second backlight source brightness value of the second display subregion by lowering the second backlight source brightness value;
- and
- driving a second backlight source in the second backlight subregion according to the adjusted second backlight source brightness value.
A display device, comprising:
- a memory;
- and
- one or more processors,
- wherein the memory stores computer-readable program codes, and the one or more processors are used to execute the computer-readable program codes to implement:
- obtaining an image to he displayed;
- determining a first backlight source brightness value of a first display subregion of the image corresponding to gray-scale values of pixels in the first display subregion, and a second backlight source brightness value of a second display subregion of the image corresponding to gray-scale values of pixels in the second display subregion, wherein a second backlight subregion corresponding to the second display subregion is adjacent to a first backlight subregion corresponding to the first display subregion;
- in response to a first backlight source in the first backlight subregion to be turned off based on the first backlight source brightness value, determining an adjusted second backlight source brightness value of the second display subregion by lowering the second backlight source brightness value;
- and
- driving a second backlight source in the second backlight subregion according to the adjusted second backlight source brightness value.
