Document Type and Number:
WIPO Patent Application WO/2020/151011
Kind Code:
A1
Abstract:
A flexible touch sensor electrode (100), comprising a substrate layer (110), a metal wire layer (120), a protective layer (150) and a lead structure (140). The substrate layer (110) is made of a flexible insulating material; the metal wire layer (120) is a flexible film layer made on the basis of a nano-metal wire, covers at least a part of the surface of the substrate layer (110) and is used for sensing an external touch operation and generating a corresponding electrical signal according to the touch operation; the protective layer (150) is made of a flexible insulating material and covers at least the part of the surface of the metal wire layer (120) away from the substrate layer (110); the metal wire layer (120) is provided with a contact area (130) for establishing an electrical connection to the outside, and within the range of the contact area (130), the protective layer (150) is in whole or in part removed; the lead structure (140) comprises a covering portion (141) and a leading-out portion (142), wherein the covering portion (141) covers the contact area (130) and directly contacts the contact area (130) so as to establish the electrical connection and wherein the leading-out portion (142) extends from the covering portion (141) and is used to electrically connect the metal wire layer (120) to the outside. The present invention further provides a corresponding manufacturing method for the electrode.
