Patent ID: 8120559

Claim:
A method of driving a liquid crystal display device including first and second liquid crystal cells, first switching means having first and second thin film transistors to drive the first liquid crystal cell and second switching means having a third thin film transistor to drive the second liquid crystal cell, the method comprising: applying a desired video signal to the first liquid crystal cell provided at an ith horizontal line (wherein i is an integer) when the (i−1)th gate line and the ith gate line are inverted into a low state after the ith and (i−1)th gate lines are supplied with gate signals of a high state; and applying the desired video signal to the second liquid crystal cell provided at the ith horizontal line when gate signals of the high state are supplied to the ith gate line and the (i+1)th gate line; wherein applying the desired video signal to the first liquid crystal cell includes: turning on the first thin film transistor in response to a gate signal applied to the ith gate line; turning on the second thin film transistor in response to a gate signal applied to the (i−1)th gate line when the first thin film transistor is turned on; turning off the first thin film transistor when the ith gate line and the (i−1)th gate line are inverted into a low state; and floating a gate terminal of the second thin film transistor when the first thin film transistor is turned off, thereby allowing the second thin film transistor to keep a ON state.
