摘要： 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.

摘要： A display device includes a display panel including a pixel connected to scan lines and a data line, a scan driving circuit, a data driving circuit, and a driving controller that controls the scan driving circuit and the data driving circuit. The pixel includes a light-emitting diode and an initialization transistor connected between a first initialization voltage line and a first electrode of the light-emitting diode and including a gate electrode connected to a first scan line among the scan lines. A first scan signal provided to the first scan line during a blank period has an active level during a predetermined initialization time duration, and the predetermined initialization time duration is set to a time duration corresponding to a luminance characteristic of the display panel.
