BACKLIGHT CONTROL METHOD AND DEVICE, AND STORAGE MEDIUM

A backlight control method and device, and a storage medium. The method comprises: acquiring a dimming image corresponding to a display frame sent by a controller, the dimming image being matched with a display image of a liquid crystal panel (201, 1701); and splitting one display frame into a plurality of dimming control frames according to the dimming image to control LEDs in a backlight module (202, 1702), the image corresponding to each dimming control frame being formed by tiling a black image and a part of the dimming image, and in the plurality of dimming control frames, the position of the black image moving in a preset direction. In the backlight control method and device, and the storage medium, the transmitted data volume can be effectively reduced and the transmission efficiency is improved, and visual residue may be relieved to improve the backlight effect. L'invention concerne un procédé et un dispositif de commande de rétroéclairage ainsi qu'un support de stockage. Le procédé consiste à : acqué
