Abstract

A display device includes: a pixel; a grayscale converter that applies a compensation value to generate an output grayscale; and a controller that provides a data voltage corresponding to the output grayscale to the pixel. The grayscale converter generates first stress value and second stress value based on the output grayscale, adds the first stress value to a first stress accumulation value to which a first accumulation coefficient is applied to update the first stress accumulation value, adds the second stress value to a second stress accumulation value to which a second accumulation coefficient is applied to update the second stress accumulation value, and generates the compensation value based on the first stress accumulation value and the second stress accumulation value. The first accumulation coefficient and the second accumulation coefficient are different from each other.
