Abstract

The invention provides a backlight source, a driving method thereof, a storage medium and a display panel. In the driving method of the backlight source, the backlight source includes a plurality of light-emitting elements, the light-emitting elements are arranged in an array, n rows of light-emitting elements form a group, and the light-emitting elements are driven to emit light group by group, wherein, n>1, and n<the total number of rows of the light-emitting element array number, n is an integer, and the driving method includes: before the first frame to be switched is switched, the data signal of the first frame to be switched is written into the second data storage area; when the first frame to be switched is switched, the The data signal in the second data storage area is read when the last group of light-emitting elements of the previous frame of a to-be-switched frame is scanned and turned on. The backlight driving method can effectively solve the problem of an incomplete display of a frame when the frame data is switched, avoid poor display, and can effectively increase the data transmission rate to meet the data transmission rate requirements when the frame is switched, thereby realizing Good switching of frames.

Description

technical field

[0001] The invention belongs to the field of display technology, and in particular relates to a backlight source, a driving method thereof, a storage medium and a display panel. Background technique

[0002] With the development of display technology, projects that use Mini LED arrays as the backlight of display panels are gradually increasing. However, such projects generally have display abnormalities when switching between different frame picture data signals at any time.

[0003] Specifically: a frame should be written into the data signal of the frame for display, but when the actual frame is switched, the previous frame has not been displayed, and the next frame is displayed. The reason is: The data signal of the next frame after switching is written into the Mini LED at the end of a frame that is not displayed, so that the display of the previous frame is incomplete. Contents of the invention
