  • Publication number: 20150364104
    Abstract: A method of driving a display panel comprises applying a first set of pixel voltages including a positive pixel voltage (+) and a negative pixel voltage (?) to subpixels of a display panel in an N-th frame, applying a second set of pixel voltages having polarities opposite to polarities of the first set of the pixel voltages to the subpixels of the display panel in an (N+1)-th frame and applying compensating values which are varied for respective data lines of the display panel. N is a natural number. A corresponding display panel is also disclosed.
