Title: LIQUID CRYSTAL PANEL DRIVING METHOD AND DEVICE
Abstract:
Disclosed are a liquid crystal panel driving method and device. The method comprises: establishing a position lookup table of all sub-pixels, wherein a first value and a second value are set in the position lookup table, the first value indicates that a sub-pixel in a corresponding position does not need grey-scale compensation, and the second value indicates that a target sub-pixel in a corresponding position needs grey-scale compensation and indicates a position of a benchmark sub-pixel to be referred to when grey-scale compensation is performed; establishing a compensation lookup table, and setting a compensated grey-scale value of the target sub-pixel according to a one-to-one correlation between the current grey-scale value of the target sub-pixel and the grey-scale value of the benchmark sub-pixel; when the liquid crystal panel is driven to display, determining a target sub-pixel needing grey-scale compensation according to the position lookup table and acquiring a corresponding benchmark sub-pixel; acquiring a compensated grey-scale value from a compensation lookup table according to the current grey-scale value of the target sub-pixel and the grey-scale value of the benchmark sub-pixel; and driving the target sub-pixel to be displayed according to the compensated grey-scale value.
