Abstract: A method of driving a display panel includes generating a high data voltage having a high gamma corresponding to a grayscale of input image data, generating a low data voltage having a low gamma less than the high gamma corresponding to the grayscale of the input image data and outputting the high data voltage and the low data voltage to pixels of a display panel. Of the high data voltage and the low data voltage, only the low data voltage is outputted to the pixels of the display panel during at least one frame.

Abstract: A method of driving a display panel is disclosed. In one aspect, the display panel includes a plurality of pixels arranged in odd and even rows and a plurality of odd and even gate lines respectively connected to the pixels of the corresponding odd and even rows. The method includes outputting odd gate signals to the odd numbered gate lines during two consecutive subframes and outputting even gate signals to the even numbered gate lines during two consecutive subframes. A frame is divided into two subframes.
