    Abstract: A display device includes: a display panel including a plurality of pixels connected to a plurality of scan lines; a scan driving circuit, which drives the plurality of scan lines in synchronization with a clock signal; and a driving controller, which outputs the clock signal. While an operating mode is a multi-frequency mode, the driving controller comparts the display panel into a first display area and a second display area. A hold frame of the multi-frequency mode includes a first section during which the first display area is driven, and a second section during which the second display area is driven. The driving controller outputs the clock signal of a normal power mode during the first section and outputs the clock signal of a low-power mode during the second section.

    Abstract: A display device includes a display panel, a data driving circuit, a scan driving circuit, and a driving controller. The driving controller receives an image signal and a control signal and controls the data and scan driving circuits to display an image on the display panel. The driving controller divides the display panel into first and second display regions based on the image signal, and outputs start and masking signals indicating starts of one frame and the second display region, respectively. First and second frames have first and second durations, respectively. The scan driving circuit sequentially drives scan lines in synchronization with the start signal and stop the driving of scan lines, corresponding to the second display region, of the scan lines, in response to the masking signal.

    Abstract: A display substrate including a scan driving circuit, a scan line, and an insulating pattern. The scan driving circuit includes a connection electrode disposed on a plurality of insulating layers, a plurality of signal lines, and a stage circuit connected to the signal lines and overlaps a non-display area. The scan line overlaps a display area and is connected to the scan driving circuit. The insulating pattern is disposed on the insulating layers, covers the connection electrode, and makes contact with a sealant.

    Abstract: A display apparatus includes a display panel including a pixel to display an image based on input image data, a driving controller which determines a driving frequency of a first display area of the display panel to be a first driving frequency and determines a driving frequency of a second display area of the display panel to be a second driving frequency less than the first driving frequency when the first display area displays a moving image and the second display area of the display panel displays a still image, and an emission driver which outputs a moving image emission signal corresponding to the first driving frequency and a still image emission signal corresponding to the second driving frequency to the display panel. A width of a non-emission period of the still image emission signal is greater than a width of a non-emission period of the moving image emission signal.
