Abstract

Disclosed is a transparent piezoelectric sheet with a frame, which has a wider effective area, is capable of more accurate touch pressure recognition, and has low manufacturing cost and a pleasing appearance. The piezoelectric sheet with a frame comprises one transparent piezoelectric membrane containing an organic polymer, one first transparent flat-plate electrode disposed to a first principal surface of the transparent piezoelectric membrane, and one second transparent flat-plate electrode disposed to a second principal surface of the transparent piezoelectric membrane. The first transparent flat-plate electrode includes a first transparent flat-plate electrode section, and the second transparent flat-plate electrode includes a second transparent flat-plate electrode section. The outline of the second transparent electrode section includes a transparent piezoelectric sheet, which when seen in plan view is positioned inside the outline of the first transparent flat-plate electrode section, and a frame covering the periphery of the transparent piezoelectric sheet. The outline of the first transparent flat-plate electrode section when seen in plan view overlaps the whole of the frame, and the outline of the second transparent flat-plate electrode section does not overlap the frame at all.

Description

technical field [0001] The invention relates to a transparent piezoelectric sheet with a frame, a touch panel and an electronic device each having a transparent piezoelectric sheet. Background technique [0002] In recent years, display and input devices in which a touch panel as an input device is provided on the front of a display device such as a liquid crystal display have been put into practical use, and are used in mobile devices such as mobile phones and operation panels of home appliances. When a touch panel display and input device is used, the user can intuitively operate the device by pressing a display on the screen. [0003] In the touch panels that have been put into practical use so far, only the position pressed by the user (in this specification, sometimes referred to as a touch position) can be detected, and the intensity of the user's press (that is, the magnitude of the pressing pressure (strength) cannot be detected. ). In this specification, sometimes ...
