Abstract
An input device manufacturing method according to an aspect of the present invention includes a lamination step of preparing a first substrate formed from a flat plate of a translucent synthetic resin, a second substrate formed from a flat plate of a translucent synthetic resin, and a sensor film formed from a translucent resin film on which a translucent electrode is disposed, and holding the sensor film between the first substrate and the second substrate to form a flat multilayer body; and a bending step of bending the flat multilayer body into a curved multilayer body retaining a curved shape. Thus, the input device can secure sufficient adhesion between the substrates and the sensor film, and can retain high detection accuracy with the sensor film.
Claims22
A method for manufacturing an input device, comprising:
- preparing a first substrate in a form of a flat plate made of a translucent synthetic resin;
- preparing a second substrate in a form of a flat plate made of a translucent synthetic resin;
- preparing a sensor film in a form of a translucent resin film on which a translucent electrode is disposed, the sensor film including a lead portion having a lead wire electrically connected to the translucent electrode;
- disposing the sensor film between a bottom surface of the first substrate and a top surface of the second substrate to form a flat laminated body in a form of a flat plate;
- and
- bending the flat laminated body into a curved laminated body which retains a curved shape thereof,
- wherein the curved laminated body includes a non-lamination portion lacking the second substrate, such that the second substrate has a cutout area viewed in a lamination direction, the disposing including:
- inserting and extending the lead portion of the sensor film through the cutout area of the second substrate to a bottom surface of the second substrate which is opposite to the top surface of the second substrate.
An input device, comprising:
- a curved laminated body having a curved detection area, the curved laminated body including:
- a first substrate which is a first resin panel made of a translucent synthetic resin and having a curved shape;
- a second substrate which is a second resin panel made of a translucent synthetic resin and having a curved shape;
- and
- a sensor film disposed between a bottom surface of the first substrate and a top surface of the second substrate, the sensor film being in a form of a translucent resin film on which a translucent electrode is disposed, the sensor film including a lead portion having a lead wire electrically connected to the translucent electrode,
- wherein the curved laminated body includes a non-lamination portion at which the curved lamination body lacks the second substrate so as to provide a cutout area in the second substrate viewed in a lamination direction,
- and wherein the lead portion extends from the sensor film through the cutout area of the second substrate to a bottom surface of the second substrate which is opposite to the top surface of the second substrate.
