DISPLAY DEVICE WITH BUILT-IN SENSOR

摘要

PROBLEM TO BE SOLVED: To provide stable sensor output by constructing a drive circuit capable of covering dispersion even when there is dispersion of characteristics of optical sensors.

SOLUTION: The display device is provided with the optical sensors 320 arranged in longitudinally and transversely arranged pixels, a circuit 312 indicating precharge timing of the optical sensors, and a circuit 313 indicating timing to output data of the optical sensors from the pixels. It has a means 430 for optionally changing an interval between the precharge timing, and the timing to output the data.
