Patent ID: 8872783

Claim:
A display device comprising: a screen including a plurality of pixels, a detection device configured to perform a detection operation for the screen, the detection operation includes detecting a position of an input made by an object touching or approaching the screen; and a detection instructing circuit configured to output a detection operation control signal to the detection device; wherein the screen repeatedly alternates between (a) each of scanning periods during which the plurality of pixels are scanned in such a manner that the plurality of pixels are sequentially brought into a selected state and (b) each of non-scanning periods during which the plurality of pixels are not scanned at all; the detection operation control signal includes a plurality of pulses which occur during at least one of the non-scanning periods, each of the plurality of pulses correspond to the detection operation, the detection operation control signal is a signal which instructs the detection device to perform the detection operation on detection targets which are the input made by the object touching or approaching the screen; and the detection device determines a timing for each of the detections in such a manner as to minimize a difference between (i) an interval between two consecutive detections, of the detections, made in a corresponding one of the non-scanning periods and (ii) an interval between two consecutive detections, of the detections, made in a period including a corresponding one of the scanning periods.
