Abstract: A display device includes a plurality of pixels in which pixels located in a selected area emit light in a sensing pattern; a plurality of optical sensors generating sensing signals corresponding to the amount of light received; and a circuit determining amounts of deterioration of the plurality of optical sensors based on the sensing signals. The circuit determines a current deterioration degree based on the amounts, sets a light emitting luminance of the sensing pattern to a first value based on the current deterioration degree, and the first value is larger than a second value associated with a previous deterioration degree when the current deterioration degree is greater than the previous deterioration degree.
