Abstract: In a method of driving a display panel, a gate signal is outputted to the display panel based on a first control signal. A gamma-corrected analog voltage is generated. A pre-charge compensating analog voltage is generated. A data voltage waveform is generated to include the generated gamma-corrected analog voltage and the generated pre-charge compensating analog voltage during one horizontal period of the display panel. The display panel has a pixel structure in which a data line is alternately connected to first and second subpixel columns adjacent to each other.

According to the method, display defects due to a difference of pre-charging levels used during plural horizontal periods may be decreased so that display quality of the display panel may be improved.
