TOUCH PANEL AND ELECTRONIC DEVICE
First Claim
1. A touch panel, comprising:
- a capacitive unit including first and second sets of touch panel electrodes separated by a dielectric flat film and lying in first and second planes, respectively, the individual electrodes of the second set extending parallel to one another with respective gaps located between adjacent touch panel electrodes of the second set; and
a pressure sensor unit including first and second sets of parallel pressure sensor electrodes separated by a piezoelectric flat film and lying in the second and a third plane, respectively, each pressure sensitive electrodes of the first set being located in a respective one of the gaps between the individual touch panel electrodes of the second set, each pressure sensor electrode of the second set opposing a respective pressure sensitive electrode of the first set with the piezoelectric film located there between so as to define an opposing pair of pressure sensitive electrodes.

Abstract
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.
