Abstract:
1. A display device, comprising: a display surface; a display functional layer adapted to control the display of information that is viewable from outside the display surface; a plurality of drive electrodes arranged in one direction separate from each other on a surface facing the display surface; a drive control section operable to perform display scanning and driving adapted to scan and drive, in one direction, the plurality of drive electrodes, and, a detection drive section for detection scanning and driving adapted to scan and drive all or part of the plurality of drive electrodes, where N is a number of display screen display scan operations and M is a number of detection scan operations, N and M are arbitrary natural numbers which satisfy the condition N<M; and a plurality of sensor lines arranged in a direction other than the one direction separate from each other, which produce an electrical change if an object to be detected comes in contact with or proximity to the display surface while the detection drive section performs the detection scanning and driving, wherein when the display scanning and driving is performed starting from the first one of the plurality of drive electrodes on one side to the last one on the other side, the detection drive section begins its scan for the detection scanning and driving starting from a drive electrode next to the first one on one side, from where the display scanning and driving begins, in the scanning direction or beyond.
