FORCE DETECTION APPARATUS, DISPLAY APPARATUS, AND ORGANIC ELECTRO-LUMINESCENCE DISPLAY APPARATUS
First Claim
1. A force detection apparatus comprising:
- a first electrode facing an input surface to which an object to be detected applies force, and configured to be supplied with a drive signal;
a conductor facing the first electrode, and supplied with a reference potential;
a second electrode and a third electrode arranged between the first electrode and the conductor;
a first dielectric layer arranged between the first electrode, and the second electrode and the third electrode; and
a second dielectric layer arranged between the second electrode and the third electrode, and the conductor,wherein the second electrode is supplied with the reference potential, and wherein a signal that is the same as the drive signal is supplied in synchronization with the drive signal to the third electrode.
