Abstract: A method of driving a display panel is disclosed. In one aspect, the display panel includes a plurality of pixels, each of the pixels including a first transistor connected to a first gate line and a pixel electrode and a second transistor connected to a second gate line and the pixel electrode. The method including alternately providing the first gate line with a gate signal and a reverse bias signal and alternately providing the second gate line with the gate signal when the first gate line is provided with the reverse bias signal and the reverse bias signal when the first gate line is provided with the gate signal.

Abstract: A display device and a driving circuit thereof are disclosed. In one aspect, the display device includes a display panel, a gamma reference voltage generator, a data driver and a driving controller. The display panel includes a plurality of pixels, each pixel including first and second sub-pixels. The gamma reference voltage generator generates one or more first gamma reference voltages each having a high gamma value greater than a reference gamma value, and one or more second gamma reference voltages each having a low gamma value less than the reference gamma value. The data driver generates a data voltage based at least in part on one or more of the first and second gamma reference voltages, and provides the data voltage to the first and second sub-pixels. The driving controller determines a gamma value and a data voltage output pattern according to a driving method of the display panel.
