    IPC: G09G3/32

    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, which is a slidable display device, includes a display panel and a data driver. The display panel includes a first display area, a second display area that is in one of a taken-in position and a taken-out-of position of the display device, and a pad area located on one side of the first display area. The display panel includes pixels disposed in the first and second display areas, and is driven in a first mode in which an image is displayed in the first display area or a second mode in which an image is displayed in the first and second display areas. The data driver generates data voltages based on pixel data, outputs the data voltages to the pixels, and controls an order of the data voltages output in the second mode.
