Abstract: A display device according to example embodiments includes an image analyzer configured to calculate contrast and load of an image of a frame based on R, G, and B image data input corresponding to the frame, an image processor configured to control a peak control coefficient applied to W image data to adaptively control peak luminance based on the contrast and the load, and to respectively generate R′, G′, and B′ image data by subtracting a product of the W image data and the peak control coefficient from each of the R, G, and B image data, a display panel including a plurality of pixels, a data driver configured to generate a data signal based on the R′, G′, B, and W image data, and to provide the data signal to the display panel, and a scan driver configured to provide a scan signal to the display panel.
