Abstract

The invention discloses a liquid crystal panel driving method and device. The method comprises the steps of establishing a position lookup table about all sub-pixels, wherein a first numerical value and a second numerical value are set in the position lookup table, the first numerical value indicates that the sub-pixel at a corresponding position does not need gray scale compensation, and the second numerical value indicates that the target sub-pixel at a corresponding position needs gray scale compensation and also indicates the position of a referential benchmark sub-pixel during gray scale compensation; establishing a compensation lookup table, and setting a post-compensation gray scale value of the target sub-pixel according to the one-to-one corresponding relation between the current gray scale value of the target sub-pixel and the gray scale value of the benchmark sub-pixel; determining the target sub-pixel needing gray scale compensation according to the position lookup table and acquiring a corresponding benchmark sub-pixel when a liquid crystal panel is driven for display, acquiring a post-compensation gray scale value from the compensation lookup table according to the current gray scale value of the target sub-pixel and the gray scale value of the benchmark sub-pixel, and driving the target sub-pixel for display according to the post-compensation gray scale value.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a method and device for driving a liquid crystal panel. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is a commonly used electronic device, and is favored by users because of its low power consumption, small size, and light weight. The current liquid crystal display is mainly a thin film transistor (Thin Film Transistor, TFT) liquid crystal display. [0003] Liquid crystal panel technology is a display technology that rotates by a specific angle based on voltage applied to liquid crystal molecules. By changing the driving voltage applied to both ends of the liquid crystal molecules, the liquid crystal molecules are rotated accordingly, so that the direction of light from the light source generated by the backlight unit changes, and the different rotation angles of the liquid crystal molecules can be used to control the liqui...
