A display apparatus includes a display panel, a timing controller and a data driver. The display panel includes a first gate line, first and second pixels connected to the first gate line and adjacent to the first gate line in a first direction, and third and fourth pixels connected to the first gate line and adjacent to the first gate line in a second direction substantially opposite to the first direction. The timing controller is configured to generate a data signal based on a first gamma and a second gamma different from the first gamma. The data driver is configured to output a first data voltage to the first pixel in a first frame, a second data voltage to the first pixel in a second frame, a third data voltage to the second pixel in the first frame, a fourth data voltage to the third pixel in the first frame, and a fifth data voltage to the fourth pixel in the first frame based on the data signal, the first and fourth data voltages having a first polarity, the third and fifth data voltages having a second polarity different from the first polarity, the first and fifth data voltages being generated based on the first gamma, the second through fourth data voltages being generated based on the second gamma.

Display apparatus and method

A timing controller for a display apparatus includes a polarity comparison part and a compensation part. The polarity comparison part compares a first polarity of a first data voltage with a second polarity of a second data voltage, the first data voltage corresponding to a first pixel in a first frame and generated based on a first gamma voltage, the second data voltage corresponding to the first pixel in a second frame and generated based on a second gamma voltage. The compensation part compensates the second data voltage based on a first look-up table, if the first polarity is the same as the second polarity, and compensates the second data voltage based on a second look-up table, if the first polarity is different from the second polarity.

Timing controller, display apparatus including the same and method of driving the display apparatus

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.
