CURVED SURFACE TOUCH PANEL, MANUFACTURING METHOD THEREOF, AND DISPLAY DEVICE WITH CURVED SURFACE TOUCH PANEL

Document Type and Number:

WIPO Patent Application WO/2012/157399

Kind Code:

A1

Abstract:

Provided is a curved surface touch panel manufacturing method, which is a method of manufacturing a capacitance-scheme touch panel having a curve surface-shaped touch surface, said method comprising the following steps for resolving not being suited to mass production, not being suited to being made in large sizes, and not being suited to complex curve surface shapes: a) using a conductive ink made of a conductive substance and a binder to create a printed plate (13) in which an electrode layer comprising a plurality of electrode regions (15) is created upon a thermoplastic plate (11); b) creating a softened curved surface object (21) by heating the printed plate (13) and molding the softened printed plate using a die (22); and c) cooling the softened printed plate or allowing same to cool, making a touch panel (10) which is a curve surface-shaped molded object.
