Patent ID: 10528206

Abstract:
First to third electrode layers (1) are laminated. A dielectric (22) disposed between the second and third electrode layers can be elastically deformed by pressing force from the first electrode layer-side to reduce distance between the second and third electrode layers. The first electrode layer is composed of first electrodes (Rxc) along a first direction (X). The second electrode layer is composed of second electrodes (Txcf) along a second direction (Y) intersecting the first direction. The third electrode layer is composed of third electrodes (Rxf) along a third direction (X) intersecting the second direction. During position-detection, the second electrodes (Txcf) function as transmission-side position-detection electrodes and the first electrodes function as reception-side position detection electrodes to constitute a mutual-capacitance touch panel unit (31). During force-detection, the second electrodes function as transmission-side force-detection electrodes and the third electrodes function as reception-side force-detection electrodes to constitute a cross-point electrostatic-capacitance touch panel unit (32).
