  • Patent number: 10779411
    Abstract: A sensor sheet-containing exterior component includes an exterior member; a sensor sheet having a sensor electrode and disposed on a back surface of the exterior member; and a mounting plate that holds the sensor sheet in close contact with the exterior member, wherein the mounting plate has a front surface shape that substantially corresponds to a back surface shape of the exterior member and is configured to engage with the exterior member, and a sensor sheet-fixing unit is provided between the mounting plate and the sensor sheet so as to fix the sensor sheet to the mounting plate along the front surface shape of the mounting plate.
    Type: Grant

  • Patent number: 10754378
    Abstract: A touch sensor includes a sensor electrode layer having a plurality of sensor electrodes, a front surface protective layer disposed on an operation surface side, and a back surface protective layer disposed on an opposite side of the operation surface, the front surface protective layer and the back surface protective layer being stacked together. In the touch sensor, the back surface protective layer includes a suppressing member configured to prevent easy detection of a change in capacitance from the opposite side of the operation surface.

  • Patent number: 10725601
    Abstract: A touch sensor includes a sensor sheet that includes a plurality of sensor electrodes, wires that extend from the sensor electrodes, and a connection portion for connection to a substrate. The sensor sheet is formed with a body portion in which the sensor electrodes are formed, and a tail portion that projects from the body portion and that includes a terminal. A protective layer is stacked on at least a part of the tail portion. A folded portion in which the sensor sheet has been bent permanently is formed in the tail portion on which the protective layer is stacked.

  • Patent number: 10310689
    Abstract: To provide a sensor panel and a sensor sheet, in which a conductive fine line and a silhouette of the conductive fine line is difficult to be seen through a display portion during illumination and in which the visibility of the display portion during illumination is good. A light diffusion layer is provided on the sensor sheet, the light diffusion layer diffusing a light of an internal light source L and transmitting the light to sensor electrodes.
