摘要： Provided is a display device that is capable of ensuring a wide dynamic range of an optical sensor even in the case where an offset due to ambient temperature changes is compensated with use of an output of a reference element. The display device has optical sensors in a pixel region of an active matrix substrate (100), wherein the optical sensors include a photodetecting sensor which outputs a sensor signal according to an amount of received light, and a reference sensor which has a configuration obtained by adding a light shielding film to the photodetecting sensor and outputs a sensor signal according to an offset component. The display device includes: an offset comparison circuit (61) that determines a degree of divergence between the sensor signal output from the reference sensor and a standard offset value; and a driving signal generation circuit (62) that adjusts a potential of a driving signal for the optical sensors according to the degree of divergence determined by the offset comparison circuit (61).

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.

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.
