Abstract
A touch panel including a first electrode plate having a first conductive film, a second electrode plate having a second conductive film facing the first conductive film, an insulating layer disposed between the first electrode plate and the second electrode plate and having an opening, and a touch plate having a pressing member disposed at a position corresponding to the opening. The pressing member transmits pressing force applied to the touch plate to the second electrode plate, to bring the second conductive film into contact with the first conductive film.
Claims6
A touch panel comprising:
- a first electrode plate having a first conductive film formed on a surface of the first electrode plate;
- a second electrode plate having a second conductive film formed on a first surface of the second electrode plate facing the first conductive film;
- a transparent insulating layer disposed between the first electrode plate and the second electrode plate and having an opening through which the first conductive film and the second conductive film can contact;
- an adhesive that bonds the first electrode plate and the second electrode plate at ends of the first electrode plate;
- a touch plate provided over a second surface of the second electrode plate opposite to the first surface;
- and
- a pressing member disposed between the touch plate and the second electrode plate at a position corresponding to the opening, a portion of the touch plate in which the pressing member is not provided is spaced apart from the second electrode plate,
- wherein the touch plate is placed over the second electrode plate and the pressing member, wherein when the touch plate is pressed, the pressing member transmits pressing force applied to the touch plate to the second electrode plate, to bring the second conductive film into contact with the first conductive film through the opening, and wherein the width of the pressing member is smaller than the width of the opening, and the width of the opening is smaller than the distance between the adhesive on the opposite ends of the first electrode plate.
A touch panel comprising:
- a first electrode plate having a first conductive film formed on a surface of the first electrode plate;
- a second electrode plate having a second conductive film formed on a first surface of the second electrode plate facing the first conductive film;
- a transparent insulating layer disposed between the first electrode plate and the second electrode plate so as to be in contact with both the first conductive film and the second conductive film;
- an adhesive that bonds the first electrode plate and the second electrode plate at ends of the first electrode plate;
- a touch plate disposed over a second surface of the second electrode plate opposite to the first surface;
- and
- a pressing member disposed between the second electrode plate and the touch plate at a position where the insulating layer is not formed, a portion of the touch plate in which the pressing member is not provided is spaced apart from the second electrode plate,
- wherein the pressing member transmits pressing force applied to the touch plate to the second electrode plate, and to bring the second conductive film into contact with the first conductive film at the position where the insulating layer is not formed, and wherein the width of the pressing member is smaller than the width of the opening, and the width of the opening is smaller than the distance between the adhesive on the opposite ends of the first electrode plate.
