Abstract: A display device includes a display panel which displays an image during a plurality of driving frames, a panel driver which drives the display panel, and a driving controller which controls a driving operation of the panel driver. The driving controller divides the display panel into a first display area and a second display area based on an image signal. Each of the plurality of driving frames includes a full frame in which the first display area and the second display area are driven, and a plurality of partial frames in which only the first display area is driven. A number of the plurality of partial frames included in each of the plurality of driving frames is changed.

Abstract: Provided is a display device. The display device includes a display panel including a plurality of pixels respectively connected to a plurality of data lines and a plurality of scan lines, a data driving circuit configured to drive the plurality of data lines, a scan driving circuit configured to drive the plurality of scan lines, and a driving controller configured to divide the display panel into a first display region and a second display region during a multi-frequency mode, and control the data driving circuit and the scan driving circuit so as to drive the first display region at a first driving frequency and drive the second display region at a second driving frequency lower than the first driving frequency, wherein, during the multi-frequency mode, the driving controller sets a frequency for each of horizontal lines in a boundary region, which is adjacent to the first display region, in the second display region to a third driving frequency between the first driving frequency and the second driving frequency.
