Transparent piezoelectric sheet, transparent piezoelectric sheet with a frame containing it, respectively, touch position detection for touch panel, display device, touch panel and electronic equipment

摘要

PROBLEM TO BE SOLVED: To provide a transparent piezoelectric sheet capable of detecting a touch pressure in a wider effective area and with higher accuracy at a low manufacture cost.;SOLUTION: The transparent piezoelectric sheet includes: a quadrangular transparent piezoelectric body film 10 which contains an organic polymer and has piezoelectricity on the entire main surface; and a first transparent plate electrode 20 laminated on a part of the first main surface of the transparent piezoelectric body film. Of four sides of the quadrangular shape of the transparent piezoelectric body film, the first to third sides and the first main surface in the vicinity are not covered with the first transparent plate electrode.;COPYRIGHT: (C)2012,JPO&INPIT
