摘要:
Provided is a display device that has a photodetection element in a pixel, and has an input function that is not dependent on the light environment. The display device includes a photosensor in a pixel region. The photosensor includes a first sensor pixel circuit that outputs a sensor signal that corresponds to charge accumulated in an accumulation period when a light source for the sensor is lit, and a second sensor pixel circuit that outputs a sensor signal that corresponds to charge accumulated in an accumulation period when the light source is extinguished. The photosensor has, as operation modes in one frame period, a sensor drive mode for obtaining sensor signals from the first and second sensor pixel circuits, a first correction data acquisition mode for acquiring first correction data for correcting the sensor signal from the first sensor pixel circuit, and a second correction data acquisition mode for acquiring second correction data for correcting the sensor signal from the second sensor pixel circuit.
