More Information
Summary:A display device includes a display panel including a plurality of pixels, a data driver configured to provide data signals to the plurality of pixels, a scan driver configured to provide scan signals to the plurality of pixels, and a controller configured to control the data driver and the scan driver. The controller includes a volatile age memory configured to store accumulated degradation amounts for the plurality of pixels, and an internal age memory configured to store backup accumulated degradation amounts generated based on the accumulated degradation amounts. The controller is further configured to compensate input image data by selectively using the accumulated degradation amounts of the volatile age memory or the backup accumulated degradation amounts of the internal age memory.
