Abstract:
1. A method of driving a display panel comprising: receiving a first subpixel data for a first subpixel; receiving a second subpixel data for a second subpixel; applying a precharge voltage to the second subpixel based on a grayscale of the first subpixel data through a data line; determining whether the second subpixel has a displaying defect based on the grayscale of the first subpixel data and a grayscale of the second subpixel data; generating a compensated grayscale of the second subpixel data when the second subpixel is determined to have the displaying defect; applying a charging voltage based on the compensated grayscale of the second subpixel data to the second subpixel through the data line; and applying a first gate signal and a second gate signal sequentially, each having an ON level for two successive horizontal periods, wherein a second horizontal period at the first gate signal is overlapped with a first horizontal of the second gate signal.
