INPUT TERMINAL

摘要

A panel of an input terminal that includes a base substrate having a first principal surface and a second principal surface opposing each other; a piezoelectric film having a third principal surface and a fourth principal surface opposing each other and made of a uniaxially stretched polylactic acid; and rigid bodies disposed at end portions of the first principal surface and the second principal surface of the base substrate so as to oppose each other across the base substrate and partially prevent a deformation caused by a twist of the base substrate. First displacement detection electrodes are formed on the first principal surface of the piezoelectric film and divide the first principal surface into four. Second displacement detection electrodes are formed on the second principal surface of the piezoelectric film and oppose the first displacement detection electrodes on the first principal surface.

1. An input terminal comprising:
a base substrate having a first principal surface and a second principal surface opposing each other; a piezoelectric film having a third principal surface and a fourth principal surface opposing each other, the third principal surface facing the second principal surface of the base substrate; a first displacement detection electrode facing the third principal surface of the piezoelectric film; a second displacement detecting electrode facing the fourth principal surface of the piezoelectric film, the first and second displacement detecting electrodes detecting a voltage produced by a bend displacement of the piezoelectric film; a first set of rigid bodies disposed at a first end of the first principal surface and the second principal surface of the base substrate; and a second set of rigid bodies disposed at a second end of the first principal surface and the second principal surface of the base substrate, the first set and second set of rigid bodies respectively opposing to each other across the base substrate to partially prevent a deformation caused by a twist of the base substrate.
