The display panel includes a first area and a second area distinguished from each other along a scan direction. Each of the first and second areas include pixels. The scan driver is configured to sequentially provide scan signals to the display panel along the scan direction. The data compensator is configured to: detect a pattern in which a difference between adjacent grayscale values in image data is greater than a reference value; and generate compensated image data by compensating for grayscale values corresponding to the second area in the image data based on the pattern corresponding to the first area. The data driver is configured to: generate data signals based on the compensated image data; and provide the data signals to the display panel.Type: ApplicationFiled: October 15, 2024Publication date: January 30, 2025Inventors: Se Byung CHAE, Weon Jun CHOE
