Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a display panel including a plurality of pixels;
a driving controller, which receives an input image signal and a control signal, and outputs a voltage control signal;
a voltage generator, which generate a first voltage and a second voltage in response to the voltage control signal; and
a scan driving circuit, which receives the first voltage and the second voltage and provides a plurality of scan signals to the plurality of pixels,
wherein the display panel is divided into a first display region, which is driven at a first operating frequency, and a second display region, which is driven at a second operating frequency,
wherein the second display region includes a boundary region adjacent to the first display region and a non-boundary region opposite to the first display region with respect to the boundary region, and
wherein the driving controller outputs the voltage control signal, such that the first voltage in a first high voltage level and the second voltage in a first low voltage level are generated when the first display region is driven,
wherein the driving controller outputs the voltage control signal, such that the first voltage in a second high voltage level lower than the first high voltage level and the second voltage in a second low voltage level higher than the first low voltage level are generated, when the non-boundary region of the second display region is driven, and
wherein the driving controller outputs the voltage control signal to generate the first voltage in a third high voltage level between the first high voltage level and the second high voltage level, and the second voltage in a third low voltage level between the first low voltage level and the second low voltage level, when the boundary region of the second display region is driven.
