Abstract: A display device includes a display panel which displays an image, and a panel driving block which receives a control signal and generating a criterion point signal including information about a criterion point for adjusting luminance of the image based on the control signal. The panel driving block receives image signals, generates a correction value based on distance information about a location of the display panel, at which each of the image signals is displayed, and the criterion point, and generates correction image signals by converting the image signals based on the correction value.

Abstract: A method of driving a display panel includes outputting a gate signal to the display panel, varying a slew rate of a data voltage to be output to the display panel according to a position in the display panel at which the data voltage is to be applied, outputting the data voltage having the varied slew rate to the display panel, and displaying a grayscale on the display panel in response to the gate signal and the data voltage having the varied slew rate.
