  • Patent number: 10921940
    Abstract: 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.

  • Patent number: 10838528
    Abstract: A first member of a cover member includes an operation portion disposed so as to correspond to a position where a sensor body is attached and having a sensor region (T) of substantially the same size as a sensor unit on the front side of the operation portion, and a design connection portion that is continuous with a side part of the operation portion and that has a surface formed so as to be continuous with a contoured surface of a wall and curved with a smaller radius of curvature than a surface shape of the operation portion.

  • Patent number: 10627936
    Abstract: A touch panel includes a panel unit. The panel unit includes a base body, a conductor row, a first connection pad, a first wiring, and a second wiring. The first wiring includes a first line segment extending from the first connection pad toward a second end, and electrically connects a first conductor and the first connection pad to each other, on the base body. The second wiring includes a second line segment extending from the first connection pad toward a first end, a third line segment extending along the first end, and electrically connects the second conductor and the first connection pad to each other, on the base body.

  • Patent number: 9164642
    Abstract: 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.

  • Publication number: 20130314347
    Abstract: 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.
