Claim Text:
1. A method of driving a display apparatus having a plurality of pixels, each pixel including a liquid crystal cell connected between a pixel electrode and a first common voltage electrode and a storage capacitor connected between the pixel electrode and a second common voltage electrode, the method comprising: determining whether image data of a current frame is changed, as compared to image data of a previous frame; when the image data of the current frame is changed, storing a voltage level corresponding to the image data of the current frame in the storage capacitor of each of the plurality of pixels; when the image data of the current frame is not changed, changing a level of a second common voltage applied to the second common voltage electrode of each of the plurality of pixels; and when a reference time elapses after the voltage level is changed to the level of the second common voltage applied to the second common voltage electrode of each of the plurality of pixels, changing the level of the second common voltage to a level before the second common voltage is changed.
