Abstract

The invention provides a method for driving a liquid crystal panel. The method is applied to the liquid crystal panel. The liquid crystal panel includes a plurality of scan lines, a plurality of data lines, and a pixel array. The method includes that a driving device controls the turn-on time of a scan line corresponding to pixel units in each row of the pixel array and the turn-on time of a corresponding data line to satisfy a first preset condition; and the driving device controls the corresponding data line of each column of pixel units in the pixel array to be increased by a pre-charge voltage to satisfy a second preset condition within a preset time slot; and the driving device controls the scan lines and the data lines to drive the pixel array according to the first preset condition and the second preset condition. An embodiment of the present invention further provides a device for driving the liquid crystal panel. With the embodiments of the present invention, the brightness uniformity of the different positions of the liquid crystal panel is improved, and the picture taste of the liquid crystal panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panels, in particular to a method and device for driving a liquid crystal panel. Background technique [0002] In today's information society, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has been widely used in all aspects of life, from small-sized mobile phones, video cameras, digital cameras, medium-sized notebook computers, desktop computers, etc. , Large-size household TVs to large-scale projection equipment, etc., and with the advantages of thinness, environmental protection, and high performance, the size is getting bigger and bigger, the resolution is getting higher and higher, and the application is getting wider and wider. [0003] The scanning lines and data lines supply power to the thin film transistors of the liquid crystal panel. Equivalent principle circuit such as figure 1 As shown in the figure a, the voltage across the capacitor C1 and the capacitor C2 is the s...
