Abstract

The invention, which belongs to the technical field of liquid crystal, discloses a backlight zone control method and device. The method comprises: at least two global backlight values are calculated according to image information of an image frame; according to the at least two global backlight values, a target global backlight value is determined based on a predetermined mode; a first backlight value of each backlight zone is calculated based on the image information of the image frame; the first backlight values of the backlight zones are adjusted according to the target global backlight value to obtain second backlight value of the backlight zones; and according to the second backlight value of the backlight zones, the backlight zones are controlled to emit backlight. According to the invention, the target global backlight value is determined according to a predetermined manner based on the at least two global backlight values and the predetermined manner is determined based on different scene modes or need modes, so that the backlight values of the backlight zones are adjusted in different scene modes or need modes and thus the optimized display effect of the image frame is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of liquid crystal display technology, and in particular to a backlight partition control method and device. Background technique [0002] Backlight partition control technology is a technology that divides the backlight layer in the liquid crystal display into M*N backlight partitions, and drives each backlight partition separately. M is the number of backlight partitions in the vertical direction, and N is the backlight partition in the horizontal direction. number. A liquid crystal display includes a liquid crystal layer and a backlight layer, and the backlight layer is a device for providing backlight to the liquid crystal layer. [0003] The current backlight partition control method includes: the display chip acquires the image information of the image frame, the image information includes the pixel value of each pixel, and the pixel value of each pixel includes: R (red, red) component, G (...
