Abstract: A display device includes: a plurality of pixels to receive data voltages based on converted grayscales; and a grayscale converter to: calculate first compensation offsets based on positions of the pixels and input grayscales for the pixels; convert the first compensation offsets into second compensation offsets according to a maximum luminance weight based on an input maximum luminance; and calculate the converted grayscales by applying the second compensation offsets to the input grayscales.

Abstract: A display device includes at least one pixel configured to receive a voltage of an initialization power source, which is supplied to an anode electrode of a light emitting element, when an enable scan signal is supplied to a scan line, and a scan driver. The scan driver is configured to supply the enable scan signal to the scan line. The enable scan signal supplied to the scan line by the scan driver has a same width during an active area of a frame regardless of an image refresh rate, and the width of the enable scan signal supplied to the scan line is changed by the scan driver during a blank area of the frame, corresponding to the image refresh rate.
