Abstract

A method for driving a liquid crystal panel including a plurality of pixel electrodes arranged in a matrix, a plurality of data lines respectively connected to the pixel electrodes in a plurality of columns, a plurality of gate lines respectively connected to the pixel electrodes in a plurality of rows, and a plurality of switching devices, respectively connected to the pixel electrodes, for connecting and disconnecting the corresponding pixel electrode and the corresponding data line based on a signal sent from the corresponding gate line. The method includes the step of applying a driving voltage having a waveform corresponding to image data used for display to each data line while inverting the driving voltage gate line by gate line and frame by frame, so as to maintain an average value of the driving voltage in each frame within a certain range.
