  • Patent number: 9041699
    Abstract: Provided is a display device that has a photodetection element in a pixel and can automatically correct a photosensor signal during operation, while resolving offset error with respect to the true black level or white level. As operation modes, a sensor row driver (5) has: (a) a sensor drive mode in which a sensor drive signal of a first pattern is supplied, and a photosensor signal that corresponds to the amount of light received by the photosensor is output to a signal processing circuit (8), and (b) a correction data acquisition mode in which a sensor drive signal of a second pattern that is different from the first pattern is supplied, and a correction photosensor signal level that corresponds to the case where the photosensor detected a black level or a white level is acquired. The photosensor signal levels obtained in the two modes while the ambient environment is controlled to a predetermined condition are stored in a memory.
