Abstract: A display device includes a display panel including a first partial panel region and a second partial panel region, and a panel driver which drives the display panel. The panel driver determines a first driving frequency for the first partial panel region and a second driving frequency for the second partial panel region. In a case where the first driving frequency and the second driving frequency are different from each other, the panel driver sets a boundary portion including a boundary between the first partial panel region and the second partial panel region, and determines a third driving frequency for the boundary portion to be between the first driving frequency and the second driving frequency.

Abstract: A display panel of a display device is divided into a first display region and a second display region. 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. 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. 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.
