Abstract: A method of driving a display panel includes: grouping m adjacent pixels, which output same color light, into one pixel-group in the display panel, where m is an integer greater than or equal to two; determining whether a unit grayscale (UG) to be implemented by the pixel-group is greater than or equal to a determined reference grayscale (REFG) by analyzing respective data signals applied to the pixel-group; performing, in response to the UG being greater than or equal to the REFG, a normal driving that implements the UG by controlling all of the m adjacent pixels to emit light with first luminance corresponding to the respective data signals; and performing, in response to the UG being less than the REFG, a combination driving that implements the UG by controlling only a portion of the m adjacent pixels to emit light with second luminance that is greater than the first luminance.
