摘要： In a display device, an object approaching a display unit is detected by referring to an image picked up by the display unit. An alternating current drive circuit drives an alternating current signal to the display unit, so that a detection circuit detects an amplitude change or a phase shift. Alternatively, a liquid crystal panel is vibrated at a predetermined frequency, so that the strength of the frequency of the vibration sound is detected. This makes it possible to more accurately detect the timing when the object touches the display unit.

摘要： Two unshielded photosensors to determine the outside-light illuminance and two shielded photosensors are placed alternating both in the longitudinal direction and in the lateral direction. Then, the difference between the output of the unshielded photosensors and the output of the shielded photosensors is obtained. Accordingly, even when the thermoelectric currents differ from each other due to a variation in characteristics between the elements and a difference in the thermal distribution between the elements, the sensor currents can be corrected, so that a photodetector circuit which stably determines the outside-light illuminance can be provided.
