  • Patent number: 10564763
    Abstract: According to an aspect, a touch detecting apparatus includes: three or more detectors; three or more detection signal lines; an integration line; three or more switches; and a control circuit. The control circuit controls the number of times an output integration is performed. During the output integration, the control circuit switches a first type switch to a decoupling mode, and switches second type switches to a coupling mode. The first type switch is one switch coupled to a first type detector, and each second type switch is coupled to one or more of second type detectors with which the second type switch corresponds. During the output integration, the integration line outputs an integrated output of outputs from the second type detectors. The output integration is performed a plurality of times corresponding to at least the number of the detectors while a combination of the second type detectors is changed.
