Patent ID: 7136040

Claim:
A method for driving a liquid crystal display (LCD) having a first gate line block and a second gate line block, the method comprising the steps of: providing a first pixel voltage to a first pixel electrode formed in the first gate line block; providing a second pixel voltage to a second pixel electrode formed in the second gate line block, the first pixel electrode and the second pixel electrode being arranged on the same column; providing a common voltage to a common electrode; providing a first data signal to a first data line formed in the first gate line block, said first data signal influencing a first voltage difference between the common voltage and the first pixel voltage stored in the first pixel electrode; providing a second data signal to a second data line formed in the second gate line block, said second data signal influencing a second voltage difference between the common voltage and the second pixel voltage stored in the second pixel electrode; and controlling the first data signal and the second data signal based on polarities of the first pixel voltage stored in the first pixel electrode and the second pixel voltage stored in the second pixel electrode to simultaneously increase or decrease the first voltage difference and the second voltage difference.
