摘要： To provide a display device having an input function that is not dependent on the light environment, multiple sensor pixel circuits that detect light in a specified detection period and hold the light amount when not in the specified detection period are disposed in a pixel region. In a frame in which input is performed using the sensor pixel circuits, a backlight is lit one time for a time in a frame period, and a first detection period and a second detection period are set one time each in the frame period. The difference between the light amount in the first detection period and the light amount in the second detection period is obtained using a difference circuit. The backlight is in an extinguished state at the beginning of the first detection period, and lighting of the backlight is started at a time during the first detection period.

摘要： 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. The signal processing circuit (8) corrects the photosensor signal in the sensor drive mode using the correction photosensor signal level that was corrected using the data for resolving offset.
