LIQUID CRYSTAL PANEL DRIVE METHOD, DISPLAY DRIVE CIRCUIT AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed are a liquid crystal panel drive method, a display drive circuit and a liquid crystal display device. The liquid crystal panel drive method comprises the steps of: A: obtaining the coordinate position of a pixel which is required to be displayed by a current frame of a liquid crystal panel and an ideal voltage value required by a grey scale which is displayed corresponding to same; and B: according to the coordinate position of the current pixel on the liquid crystal panel, determining a compensation voltage which is used for improving the liquid crystal panel uniformity, and then loading the compensation voltage to a corresponding data line. The present invention effectively improves the charging time difference of each region of a liquid crystal panel which is generated by charging caused by a waveform delay variation resulting from resistance and capacitance, improves the display uniformity of a liquid crystal panel, particularly a large-size liquid crystal panel, and improves the appearance thereof.
