Abstract: A display device and an electronic device including the same are disclosed. In one aspect, the display device includes a display panel divided into first and second regions. The display device also includes a scan driver including a plurality of first scan stages configured to sequentially provide a scan signal to the pixels in the first region, a plurality of second stages configured to sequentially provide the scan signal to the pixels in the second region, and a scan switch connected between the first and second stages. One of the first scan stages is configured to provide a scan carry signal to the scan switch, the scan switch is configured to selectively provide the scan carry signal or a scan disable signal to the second scan stages, and the scan carry signal and the scan disable signal are configured to halt the operation of the second scan stages.

Abstract: A luminance controller according to example embodiments includes a gamma set selector to select a reference gamma set from among first through N-th gamma sets respectively corresponding to first through N-th reference luminances, based on a target luminance of a display panel; an initialization voltage selector to select an initialization voltage corresponding to the reference gamma set, from among first through N-th initialization voltage offsets respectively corresponding to the first through N-th gamma sets; a common voltage selector to select a common voltage corresponding to the reference gamma set from among first through N-th common voltage offsets respectively corresponding to the first through N-th gamma sets; and a determiner to determine a target initialization voltage based on the target luminance and the initialization voltage, and to determine a target common voltage based on the target luminance and the common voltage.
