Patent ID: 8564520

Claim:
A method for driving a display panel, the display panel including a plurality of pixels, each of the plurality of pixels including a cholesteric liquid crystal capacitor, the method comprising: applying a common voltage to the display panel; and displaying a video on the display panel by applying a data voltage to at least one of the plurality of pixels, the data voltage having a phase which is one of inverted to and substantially the same as a phase of the common voltage with respect to a reference voltage, wherein the displaying a video on the display panel further comprises: sequentially applying a plurality of gate signals to a plurality of gate lines, the plurality of gate lines being disposed on the display panel; applying the data voltage having the phase which is one of inverted to the phase of the common voltage to at least one of a plurality of data lines disposed on the display panel to display a black image in a first frame; and applying the data voltage having the phase which is substantially the same as the phase of the common voltage to the at least one of a plurality of data lines disposed on the display panel, to display a color image in a second frame subsequent to the first frame.
