A sensor is provided and includes a first control line; a first signal line; a first auxiliary line; a first detection electrode; a first detection switch connected to the first detection electrode, the first control line and the first signal line; and a first shielding electrode connected to the first auxiliary line, wherein the first shielding electrode is located to overlap the first signal line via an insulating film.

Sensor and sensor-equipped display device

According to one embodiment, a sensor includes a first control line, a first signal line, a first detection switch, a common electrode, a first detection electrode, a first circuit and a second circuit. The common electrode is located above the first control line, the first signal line and the first detection switch, opposed to the first control line, the first signal line and the first detection switch. The first detection electrode is located above the common electrode. The first circuit and the second circuit are located under the common electrode, and are opposed to the common electrode.

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.

Touch detecting apparatus, display apparatus with touch detection function, and touch detection method

According to an aspect, a touch detecting apparatus includes: three or more detectors; a generating circuit that performs generation for generating a plurality of pieces of output data corresponding to a plurality of patterns and having resolution lower than resolution corresponding to the number of the detectors based on outputs from the detectors; a calculating circuit that performs calculation for calculating, for each of the detectors, a composite value to be used to derive a detection result of each of the detectors based on the pieces of output data corresponding to the patterns.
