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.
