Abstract
A display device includes a deterioration evaluation region including dummy pixels and a display region. A control circuit determines a gray level for a first display pixel and determines whether the first display pixel is in a first deterioration mode or a second deterioration mode based on a driving history of the first display pixel. The control circuit determines, in the first deterioration mode, a data signal to be supplied to the first display pixel based on the gray level and the driving history of the first display pixel. The control circuit determines, in the second deterioration mode, a data signal to be supplied to the first display pixel based on the gray level, the driving history of the first display pixel, and measurement results about a current-voltage characteristic acquired from dummy pixels in the deterioration evaluation region of the same color as the first display pixel.
