    摘要: A display device includes a casing (11) an operation plate, a piezoelectric sensor, a controller, and a display. The piezoelectric sensor includes a piezoelectric film, an optically clear adhesive, a plurality of first electrodes, a plurality of first wiring lines, a plurality of second electrodes, a second wiring line, a pair of substrates and a reception circuit. The piezoelectric sensor is bonded to a surface of the operation plate on a side opposite to an operation surface. The plurality of first wiring lines includes a region, which overlaps one of the piezoelectric film and the plurality of second electrodes but does not overlap either the piezoelectric film or the plurality of second electrodes at the same time when a first surface is viewed from a front. The region is provided between the second electrodes when the first surface is viewed from the front.

    摘要: An electronic device is provided that includes a flexible body, a stress sensor, and a detector. The stress sensor has a piezoelectric film that is deformed by a stress resulting from bending of the body. The stress sensor detects stresses that develop respectively at an end part and a central part of the body. When the end part and the central part are bent at the same radius of curvature, the stress sensor outputs output values such that a first output value based on a stress having developed at the end part is different from a second output value based on a stress having developed at the central part. Moreover, the detector detects at least one of the first output value and the second output value having exceeded a given threshold.

    摘要: A touch panel includes a capacitive touch panel unit and a pressure sensor unit. The capacitive touch panel unit includes a film and touch panel electrodes, and the pressure sensor unit includes a film and pressure sensor electrodes. An electrode layer in which the pressure sensor electrode is formed is the same as an electrode layer in which the touch panel electrode is formed. An electrode layer in which the pressure sensor electrode is formed has a non-formation portion where the pressure sensor electrode is not formed at the position opposite to the touch panel electrode.

    摘要: The present invention provides a technology with which precision in detecting pressing can be enhanced, even if the total number of films in a touch panel is decreased. The touch panel includes a capacitive touch panel unit and a pressure sensor unit, wherein the capacitive touch panel unit includes a film and touch panel electrodes, and the pressure sensor unit includes a film and pressure sensor electrodes. An electrode layer in which the pressure sensor electrode is formed is the same as an electrode layer in which the touch panel electrode is formed, and an electrode layer in which the pressure sensor electrode is formed has a non-formation portion where the pressure sensor electrode is not formed, at the position opposite to the touch panel electrode.

    摘要: A detection device includes a panel having opposed main surfaces including an operation surface and a rear surface. A support structure is located on at least one of the main surfaces and prevents warping of the panel while permitting the operation surface to be deformed in response to a pressing operation applied to the operation surface. A sensor for sensing the pressing operation applied to the operation surface is provided on one of the main surfaces at a location where at least a portion of the sensor does not overlap the support structure in plan view.
