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.

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.
