Title:
CAPACITIVE CURVED TOUCH PANEL AND METHOD FOR FABRICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/045325
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a capacitive curved touch panel for which greater thinness and lighter weight are achieved. Provided is a capacitive curved touch panel, formed from: a capacitive curved touch panel substrate which is heat molded in a prescribed curved shape, comprising a transparent panel substrate (2) formed from a transparent resin base, a decorative printed layer (5) which is formed on the outer edge part of the back surface of the transparent panel substrate (2), a step prevention layer (7) which is formed from a transparent resin material formed in a level manner and spans and covers an area on the inner side of the decorative printed layer (5) in the back surface of the transparent panel substrate (2) whereupon the decorative printed layer (5) is formed and the back surface of the decorative printed layer (5), a sensor unit (10) which is formed from a transparent electrode layer (8) which is formed upon the back surface of the step prevention layer (7), and a transparent protective film (9) which is formed to cover the whole of the sensor unit (10) except for a thermal press bonding region for an external connection substrate; and the external connection substrate (11), which is thermally press bonded to the thermal press bonding region of the sensor unit (10) of the capacitive curved touch panel substrate (50).
