Abstract: A display device is disclosed that includes a display panel, a timing controller, and a data driver. The display panel includes a plurality of pixels. The timing controller is configured to calculate an on-pixel ratio of first image data and correct the first image data into second image data based on the on-pixel ratio. The data driver is configured to generate a data signal based on the second image data and provide the data signal to the pixels. The timing controller calculates the second image data by estimating a temperature of the display panel using the on-pixel ratio and gamma-correcting the first image data in response to the temperature.
