TOUCH PANEL PROVIDED WITH PRESSING FORCE MEASUREMENT

摘要

A touch panel equipped with both an electrostatic sensor and a piezoelectric sensor, wherein the touch panel solves the problems of increased panel thickness, changes in the optical properties, and increased manufacturing costs. This touch panel (40) is provided with force measurement using a piezoelectric body (31) and capacitive position detection. The force measurement uses a pair of electrodes (13, 12) arranged with the piezoelectric body (31) sandwiched therebetween. The position detection uses one electrode (11) and another electrode (12). At least one top electrode (16) is disposed on the side of the top surface of the piezoelectric body, and at least one bottom electrode (17) is disposed on the side of the bottom surface of the piezoelectric body. One electrode from among the pair of electrodes used in force measurement is a bottom electrode, and at least one electrode from among the two electrodes used in position detection is a top electrode.
