Title:
CAPACITANCE TYPE TOUCH MEMBER AND METHOD FOR PRODUCING THE SAME, AND CAPACITANCE TYPE TOUCH DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/113437
Kind Code:
A1
Abstract:
Provided are a capacitance type touch member which has a flexible or stereoscopic shape and has a light transmissive detection electrode, and a method for producing the same; and a capacitance type touch detection device provided with the capacitance type touch member. A capacitance type touch member (10) comprised of a film-like or plate-like support element (1) composed of an insulating material, which has a flexible or stereoscopic shape; a detection electrode (2) which is disposed on at least a part of one surface of the support element (1), and is composed of a light transmissive conductive layer containing a carbon nano linear structure such as a carbon nanotube; and a lead wire (3) drawn from the detection electrode (2), is produced. A capacitance type touch detection device is comprised of the touch member (10) and a capacitance detection circuit (60) which is electrically connected to the detection electrode (2) via the lead wire (3), to detect the change of the capacitance due to the access or contact of a human body to a touch surface (4). The detection electrode (2) may be coated with a protection film, and the surface of the protection film may be used as a touch surface.
