DISPLAY PANEL WITH PRESSING SENSOR AND ELECTRONIC DEVICE WITH PRESSING INPUT FUNCTION

摘要

An electronic device with pressing input function has a substantially rectangular parallelepiped housing. In the housing, a pressing sensor, a display panel, a protection member, and a computation circuit module are arranged. In the display panel, a polarization plate is arranged on a first side of a liquid crystal panel. In the pressing sensor, electrodes are formed on both planar faces of a piezoelectric film having double refractivity. The pressing sensor is arranged on the operation surface (the display face) side of the housing relative to the front polarization plate.

主权项

1. A display device comprising:
a display panel having an image forming panel that forms a display image by controlling a light emitted to a first side thereof, and a polarization plate arranged adjacent the first side of the image forming panel; and a pressing sensor having a piezoelectric film comprising a chiral polymer, the pressing sensor being arranged adjacent a side of polarization plate opposite to the image forming panel.
