DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME
First Claim
1. A method of driving a display apparatus having a plurality of pixels that respectively store a voltage level corresponding to a data signal and respectively include a storage capacitor connected between a 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; and
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.

10. A display apparatus, comprising:
-
a pixel unit including a plurality of pixels, each of the plurality of pixels stores a voltage level corresponding to a data signal and includes a storage capacitor connected between a pixel electrode and a second common voltage electrode; a common voltage driving unit configured to supply a second common voltage to the plurality of pixels; and a compensation control unit, the compensation control unit being configured to determine whether image data of a current frame is changed, as compared to image data of a previous frame, wherein, when the image data of the current frame is changed, the compensation control unit is configured to control the common voltage driving unit to store a voltage level corresponding to the image data of the current frame in the storage capacitor of each of the plurality of pixels, and wherein, when the image data of the current frame is not changed, the compensation control unit is configured to control the common voltage driving unit to change a level of the second common voltage applied to the second common voltage electrode of each of the plurality of pixels. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
