The invention provides a backlight control method, device and system and a storage medium. The method comprises the steps of determining next frame target brightness corresponding to a backlight module according to next frame display data corresponding to a liquid crystal panel; according to the current brightness of the backlight module, determining the adjustment brightness of the backlight module, wherein the difference value between the adjustment brightness and the current brightness is larger than the difference value between the target brightness and the current brightness; and controlling the backlight module to display the adjusted brightness, and gradually changing the adjusted brightness into the target brightness. According to the backlight control method, device and system and the storage medium provided by the invention, the flexibility can be improved by controlling the adjustment brightness to amplify the output value of the panel under the condition that the gray level is greatly changed, and the adjustment brightness displayed by the backlight module can be controlled to gradually change into the target brightness, so that the final brightness is accelerated to reach the required target brightness, so the response time can be effectively shortened, that is, the response time of the final image felt by the user is improved, and the user experience is improved.
Description
technical field [0001] The present invention relates to backlight control technology, in particular to a backlight control method, equipment, system and storage medium. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, liquid crystal display has become the mainstream technology of flat panel display due to its low power consumption, light weight, and brilliant colors, and is widely used in our daily life. In consumer electronic products, the drive response speed of LC (Liquid Crystal, liquid crystal) used for liquid crystal display panels is relatively slow, so the response time of image output is relatively long, and the afterimage of the previous image is prone to remain for a long time. [0003] In the prior art, the OD (Over Drive) technology is generally used to improve the above phenomenon, and the response time is shortened by amplifying the value output to the LCD panel, but the v...
