Abstract: A control method, a dimming controller, and a display device, the method including: acquiring a voltage state of each output channel of any number of drive units, where the voltage state includes an undervoltage state, an overvoltage state, and a steady state, and a voltage state of an output channel of each drive unit is determined by the drive unit according to a voltage of the output channel within preset time and a steady operation voltage range; and adjusting, according to the voltage state of each output channel of the any number of drive units, voltages of power supply terminals of all light-emitting units in the back light unit. This solution can reduce power loss of the display device and ensure display of pictures.

Abstract: Provided are a backlight control method, a device, and a storage medium, where the method includes: acquiring a dimming image corresponding to a display frame sent by a controller, the dimming image matching a display image on a liquid crystal panel; splitting, according to the dimming image, one display frame into a plurality of dimming control frames to control LEDs in a backlight module; where an image corresponding to each dimming control frame is composed of a black image and a partial dimming image which are spliced, and in the plurality of dimming control frames, positions of black images move in a preset direction.

Abstract: A control method for a backlight circuit includes: obtaining a plurality of pieces of dimming data in a preset period of time; determining total accumulated electric energy received by the backlight source according to the plurality of pieces of dimming data in the preset period of time; and generating a first voltage control signal when the total accumulated electric energy reaches a preset electric energy threshold. The dimming data is used to control a backlight source to emit light. The preset period of time is from an initial moment of continuous light emission of the backlight source to a current moment. The first voltage control signal is used to reduce the working voltage of the backlight source. When the total accumulated electric energy reaches the preset electric energy threshold, reducing the working voltage of the backlight source does not affect a light emitting brightness of the backlight source.
