Patent ID: 7522140

Claim:
A method for driving a liquid crystal display device by supplying image data to be written to at least one pixel of the liquid crystal display device, comprising: obtaining an image data value on the basis of a data value of an image signal in a previous vertical synchronization interval and a data value of an image signal in a current vertical synchronization interval, the obtained image data value being lesser than the data value of the current image signal if the data value of the current image signal is lesser than the data value of the previous image signal, and the obtained image data value being greater than the data value of the current image signal if the data value of the current image signal is greater than the data value of the previous image signal; and supplying the obtained image data value to at least one pixel at least one time within one vertical synchronization interval and supplying another image data value to the at least one pixel at least one time within the one vertical synchronization interval, in order to improve step response characteristics of the liquid crystal display device.
