Abstract: In a gamma voltage correction method for a display device including a first display area and a second display area, the gamma voltage correction method includes: correcting a gamma voltage for each sub-pixel of the first display area based on measured light characteristics of a first area of the first display area in a plurality of gray levels; and correcting a gamma voltage for each sub-pixel of the second display area based on measured light characteristics of a second area of the first display area around the second display area and measured light characteristics of the second display area in the plurality of gray levels.

Abstract: A display device includes: a display panel; a driving frequency converter circuit configured to convert a driving frequency according to an input image data. A common voltage controller outputs a common voltage data corresponding to the driving frequency; and a common voltage generator receives the common voltage data to generate a common voltage and outputs the common voltage to the display panel. The common voltage has an inclined waveform within an integer multiple of a frame period.
