摘要： A capacitor charged beforehand is discharged according to a light surrounding a display unit. A data is decreased similarly to the voltage between the electrodes of the capacitor. A trigger signal is outputted if the data becomes equal to or less than a threshold value. A clock signal whose cycle of changing levels gradually becomes long is generated. A count value is updated at each change of the clock signal's level and the updated count value is outputted. The count value is sampled when the trigger signal is outputted.

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.

A control method for the display device includes using the light sensor to measure outside illuminance and using an output of the temperature sensor to correct an output of the light sensor, thereby adjusting luminance in the display region. The display device may further include an opposed substrate in opposition to the array substrate, a liquid crystal layer sandwiched between the two substrates to form the predetermined display region, and a backlight, thereby constituting a liquid crystal display device. Another configuration of a display device has a predetermined display region and includes an array substrate equipped with a drive circuit for display, and a light sensor installed on the array substrate for measuring outside illuminance, a filtering circuit for filtering a signal output from the light sensor and a processing circuit for processing the signal output from the light sensor and then filtered with the filtering means.
