12. A display device comprising:
a display panel comprising a plurality of pixels, each of which receives a driving voltage through a first voltage line;
a driving controller configured to output a voltage control signal; and
a voltage generator configured to provide the driving voltage to the first voltage line and to determine a voltage level of the driving voltage based on the voltage control signal,
wherein the driving controller determines a gate-source voltage corresponding to an input image signal, determines an offset voltage corresponding to an image pattern of the input image signal, and generates the voltage control signal based on the gate-source voltage and the offset voltage.
