Patent ID: 8860770

Claim:
A method of driving a display panel, the method comprising: driving a first sub area and a second sub area of a pixel part in a two-dimensional (2D) image mode, wherein a first luminance difference exists between the first and second sub areas in the 2D image mode; and driving the first sub area and the second sub area of the pixel part in a three-dimensional (3D) image mode, wherein a second luminance difference exists between the first and second sub areas in the 3D image mode, the second luminance difference being smaller than the first luminance difference, wherein the first sub area includes a first liquid crystal (LC) capacitor connected to a data line and an n-th gate line (wherein, n is a natural number) through a first switching element, the second sub area includes a second LC capacitor connected to the data line and the n-th gateline through a second switching element, and the second sub area further includes a down capacitor connected to the second LC capacitor and an n+1-th gate line through a third switching element, and a data voltage applied to the second LC capacitor of the second sub area is partially shared with the down capacitor of the second sub area to cause the first luminance difference.
