Patent number: 10921940Abstract: In a touch sensor in which a touch sensor body is attached to a cover member, the cover member includes: a first member made of a glass plate and having a first surface and a second surface that is an opposite surface of the first member from the first surface; and a resin film made of polyvinyl butyral (PVB) and formed on the second surface. The resin film is located between the first member and the touch sensor body.Type: GrantFiled: February 22, 2018Date of Patent: February 16, 2021Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Shoji Fujii, Hirofumi Komiya, Keisyu Muraoka, Keishiro Murata

Patent number: 9164642Abstract: A touch panel includes an upper substrate, an upper conductive layer, a lower substrate, a lower conductive layer, and dot spacers. The upper substrate includes a substrate layer and a hard coat layer disposed on the top surface of the substrate layer. The upper conductive layer is disposed on the bottom of the upper substrate. The lower conductive layer is disposed on the top surface of the lower substrate in such a manner as to confront the upper conductive layer with a predetermined space therebetween. The dot spacers are disposed on the lower conductive layer. The hard coat layer has an outer surface with a ten-point average roughness Rz in the range from 17.7 ?m to 40.0 ?m, inclusive.Type: GrantFiled: July 31, 2012Date of Patent: October 20, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Shoji Fujii, Yasuro Niguma, Keisyu Muraoka

Publication number: 20130314347Abstract: A touch panel includes a first substrate, multiple translucent first electrodes, multiple first wirings, a second substrate, multiple translucent second electrodes, multiple second wirings, and a light-shielding layer. The first wirings include first ends connected to the respective first electrodes, and second ends extending to the edge of the first substrate. The second wirings include first ends connected to the respective second electrodes, and second ends extending to the edge of the second substrate. The light-shielding layer is formed on the first substrate in a position covering at least a part of the first wirings and also corresponding to at least a part of the second wirings.Type: ApplicationFiled: May 15, 2013Publication date: November 28, 2013Applicant: PANASONIC CORPORATIONInventors: Keisyu MURAOKA, Tamotsu YAMAMOTO
