Abstract
A display device includes: a display panel including first group pixels connected to a first gate line to receive first data voltages, and second group pixels connected to the first gate line to receive second data voltages; a backlight source to provide light to the display panel; a signal controller to divide horizontal image signals into first group image signals and second group image signals, to extract a first maximum grayscale image signal from the first group image signals, and to extract a second maximum grayscale image signal from the second group image signals; a power supply to generate first and second gamma driving voltages from a reference gamma driving voltage based on a grayscale level of the first maximum grayscale image signal and a grayscale level of the second maximum grayscale image signal.
