Abstract
A display device includes a display panel. The display panel includes a pixel including a light emitting element. A compensator calculates a current stress of the light emitting element based on input grayscale values sequentially provided for the pixel during a specific time and generates a first output grayscale value by compensating for a first input grayscale value provided at a current time point based on the current stress. A driver generates a data signal based on the first output grayscale value and supplies the data signal to the pixel. The compensator sets the first output grayscale value to be less than the first input grayscale value in case that the input grayscale values are greater than a reference grayscale value.
