1. A display device, comprising:
a display panel including a plurality of data lines, a plurality of scan lines, and a plurality of pixels connected to the plurality of data lines and the plurality of scan lines; and
a panel driver configured to drive the display panel,
wherein, in an active period of a frame period, the panel driver generates data voltages based on a gamma voltage, provides the data voltages to the plurality of pixels through the plurality of data lines, and provides scan signals having a gate-on voltage to the plurality of pixels through the plurality of scan lines,
wherein, in a black period of the frame period, the panel driver outputs a black data voltage to the plurality of data lines, and outputs a gate-off voltage to the plurality of scan lines, and
wherein, in a display-off period, the panel driver outputs the gamma voltage to the plurality of data lines, outputs the gate-off voltage to the plurality of scan lines, and adjusts at least one of the gamma voltage and the gate-off voltage.
