METHOD OF DRIVING A LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY DEVICE EMPLOYING THE SAME

摘要

A method of driving a liquid crystal display panel drives a liquid crystal display panel including a liquid crystal structure including a pixel electrode, liquid crystal layer, and common electrode, a switching transistor connected between the pixel electrode of the liquid crystal structure and a data line, and a liquid crystal display pixel including a storage capacitor connected to the pixel electrode of the liquid crystal structure. Here, the method calculates a cumulative driving time of a liquid crystal display panel by accumulating driving time of the liquid crystal display panel, checks whether the cumulative driving time of the liquid crystal display panel reaches a deterioration reference time, and changes a gate-off voltage applied to a gate terminal of a switching transistor and a common voltage applied to a common electrode of a liquid crystal structure when the cumulative driving time of the liquid crystal display panel reaches the deterioration reference time.
