Surface panel and method of manufacturing the same

摘要

The surface panel includes a transmissive resin layer and a sensor film closely attached to a back surface of the resin layer. The sensor film includes a base film, a frame-shaped decorative portion on a front surface of the base film, and a transmissive electrode layer and right and left wiring layers on a back surface of the base film. The sensor film is closely attached to and along the back surface of the resin layer. The right and left wiring layers are closely attached to the corresponding right and back-surface left portions. Consequently, the area that is allocated for the transmissive region and the electrode layer can be increased.

主权项

1. A front panel comprising:
a panel body formed of a single transmissive resin layer having a front surface and a back surface opposite to the front surface, the transmissive resin layer having a main panel portion and at least one side portion extending backward from the main panel portion, the side portion including a bent portion; and a sensor film fixed to and in contact with the back surface of the transmissive resin layer along the main panel portion and the side portion including the bent portion, the sensor film configured to sense presence of a human finger in proximity thereto, wherein the front surface includes:
a front main surface corresponding the main panel portion and providing an operation face or display face; anda front side surface corresponding to the side portion, the front side surface extending backward from the front main surface, wherein the back surface includes:
a back main surface opposite to the front main surface; anda back side surface opposite to the front side surface, and wherein the sensor film includes:
a base film made of a single transmissive layer having a first surface facing the transmissive resin layer and a second surface opposite to the first surface, the base film extending along the back main surface and the back side surface of the transmissive resin layer;a transmissive electrode layer provided on the second surface of the base film in a first region corresponding to the back main surface of the transmissive resin layer;a wiring layer electrically connected to the transmissive electrode layer, the wiring layer being provided on the second surface of the base film in a second region corresponding to the back side surface of the transmissive resin layer, the wiring layer being a conductive organic layer;a decorative portion provided on the first surface of the base film in the second region so as to cover and hide the wiring layer viewed from the front surface, wherein the decorative portion, the base film, and the wiring layer form a three-layered laminated structure in the second region such that the decorative portion extends along and is in contact with the back side surface including a curved surface corresponding to the bent portion, wherein the transmissive electrode layer is disposed in a transmissive region surrounded by the decorative portion formed in a shape of a frame.
