Abstract
A degradation compensation circuit and a display device including the same are discussed. When noise is included in sensed data indicating a degradation amount of a display panel, the degradation compensation circuit cancels the noise component and/or an effect of the noise component on degradation compensation. The degradation compensation circuit can receive initial sensed data indicating a characteristic of a display panel from a sensing circuit for sensing a pixel signal of the display panel, store therein a first noise level of the initial sensed data at each pixel coordinate, receive current sensed data indicating degradation of the display panel from the sensing circuit, correct a second noise level of the current sensed data to the first noise level of the initial sensed data, calculate a difference between the current sensed data and the initial sensed data, and extract degradation compensation data corresponding to the difference.
