Abstract: A display device includes a display panel, a data driver, a scan driver, and a driving controller. The display panel includes a first display area and a second display area, which operate at different frequencies from each other in a multi-frequency mode. The driving controller controls the data driver and the scan driver. The driving controller generates boundary compensation data by compensating for boundary image signals, which are input to correspond to a boundary area of the first display area in the multi-frequency mode and drives the data driver based on a compensation image signal including the boundary compensation data.

Abstract: Disclosed is a display device including a display panel including a plurality of pixels and a voltage generator providing an anode initialization voltage to the pixels. The display panel is divided into a first display area operating at a first operating frequency and a second display area operating at a second operating frequency. While pixels, which correspond to the first display area, from among the plurality of pixels are driven, the anode initialization voltage has a first voltage level. While pixels in the second display area from among the plurality of pixels are driven, the anode initialization voltage has a second voltage level different from the first voltage level.

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.
