Driving Backlight Method, Display Device And Storage Medium

A display device, comprising:

• one or more processors;
• one or more computer-readable memories,
• wherein the one or more computer-readable memories storing instruction codes, the instruction codes are executable by the one or more processors to drive a backlight of liquid crystal of the display device, the backlight comprises a plurality of backlight scanning areas, and each luminous body corresponding to each backlight scanning area is driven independently, wherein driving a backlight of liquid crystal of the display device comprises:
• acquiring display gray scale of a current frame of image and display gray scale of a previous frame of image in a backlight scanning area;
• determining a first backlight duty ratio according to the display gray scale of the current frame of image and the display gray scale of the previous frame of image;
• if black frame insertion time in the first backlight duty ratio is smaller than a first black frame insertion time, acquiring a second backlight duty ratio, wherein black frame insertion time in the second backlight duty ratio is greater than or equal to the first black frame insertion time, and the first black frame insertion time is not less than 20% of a frame period;
• and
• determining drive timing of luminous bodies of the backlight scanning area in the current frame according to the second backlight duty ratio.

A computer-readable storage medium, storing computer-readable program codes, wherein the computer-readable program codes is executable by one or more processors to drive a backlight of the liquid crystal display device, wherein driving a backlight of liquid crystal of the display device comprises:

• acquiring display gray scale of a current frame of image and display gray scale of a previous frame of image in a backlight scanning area;
• determining a first backlight duty ratio according to the display gray scale of the current frame of image and the display gray scale of the previous frame of image;
• if black frame insertion time in the first backlight duty ratio is smaller than a first black frame insertion time, acquiring a second backlight duty ratio, wherein black frame insertion time in the second backlight duty ratio is greater than or equal to the first black frame insertion time, wherein the first black frame insertion time is not less than 20% of a frame period;
• and
• determining drive timing of luminous bodies of the backlight scanning area in the current frame according to the second backlight duty ratio.
