(EN) Touch panel having press detection function
要約
(EN)

A piezoelectric sensor that can perform position detection and load detection. The touch panel having press detection function can detect the pressing load inputted to the pressing surface. An upper electrode, an upper insert member, an intermediate electrode, a lower insert member, and a lower electrode are arranged away from the pressing surface in this order. Among the upper electrode, the intermediate electrode, and the lower electrode, capacitance detection electrodes Cx, Cy for detecting the pressing position, and detection electrodes S for measuring the electric charge according to the pressure when the operation is inputted to the touch panel 1 having press detection function are included. One of the upper insert member and the lower insert member is composed of an insulating body, and the other is composed of a piezoelectric body.
