METHOD OF DRIVING DISPLAY PANEL AND DISPLAY APPARATUS FOR PERFORMING THE SAME
A method of driving a display panel and a display apparatus having a plurality of gate lines and a plurality of data lines that cross the gate lines. The method includes determining whether to compensate a gate signal or not according to input image data displayed on a display panel, transmitting a first gate signal having a first falling waveform to a first gate line and a second gate signal having a second falling waveform different from the first falling waveform to the second gate line. A first gate clock signal may be adjusted when the gate signal is determined to be compensated. A timing controller may compensate the first gate signal when an artifact would be displayed based on a variation in brightness when a first subpixel row to which the first gate signal is applied is brighter than a second subpixel row for a same target luminance.
