LIQUID CRYSTAL DISPLAY DEVICE DRIVE METHOD AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of a vertical crosstalk like display fault by transmitting a specified image signal to an image signal line at the same polarity as the image signal applied to a pixel electrode just after a blanking period during the blanking period. SOLUTION: An image signal 21 contains a liquid crystal drive voltage Vsig in which the polarity is inverted for a counter electrode potential 12 at every period T and is added with a liquid crystal drive voltage Vpc of a maximum voltage VLmax or above applied to a pixel electrode in the just before a blanking period T1. Further, gate signal pulsesβandαwhose timings are deviated by one pixel component are applied from a circuit block for the blanking period T1 to the signal write-in transistors connected to the image signal lines adjacent to pulse signals 23 (n) and 23 (n+1)for gate electrodes of signal write-in transistors connected to n-th and (n+1)-th image signal lines. At this time, a signal 24n containing the liquid crystal drive voltage Vpc of the VLmax or above is transmitted to the n-th image signal line.
