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.

摘要： Disclosed is a display device that can compensate for variations of light-detecting element while securing a wide dynamic range of light sensors. This is a display device equipped with light sensors having operation modes for one frame period, which are: a sensor driving mode for obtaining sensor signals, a first correction data acquisition mode for obtaining a first correction data, and a second correction data acquisition mode for obtaining a second correction data. This display device further includes a memory that stores light sensor signal levels obtained, under a controlled ambient environmental condition, by driving the light sensors in the above-mentioned three modes as offset elimination data. A signal-processing circuit uses the first correction data and the second correction data, and the light sensor signal level corrected with the offset elimination data to correct the light sensor signal obtained in the sensor driving mode.
