    Abstract: A display device includes a display panel, a data driver, a scan driver, and a light emitting driver. The display panel includes a first display area and a second display area. The display panel displays a first image on the first display area and the second display area in a first mode, and displays a second image on the first display area in a second mode. The light emitting driver activates emission control signals applied to the first display area and the second display area in the first mode. The light emitting driver activates emission control signals applied to the second display area during a first partial frame in the second mode, and maintains the emission control signals applied to the second display area in a deactivation state during a plurality of second partial frames in the second mode.

    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.
