  • Patent number: 9778809
    Abstract: In a coordinate detection apparatus, a resistance-film is formed on a substrate made of an insulating material. A common electrode applies a voltage to the resistance-film, the common electrode extending along a plurality of a resistance-film removal areas formed by removing portions of the resistance-film. A voltage application part applies the voltage to the common electrode. The voltage is applied from the voltage application part to the resistance-film through the common electrode to generate a potential distribution in the resistance-film. A coordinate position of a contact position at which the resistance-film is contacted is detected by detecting a potential of the resistance-film at the contact position.

  • Patent number: 7136049
    Abstract: An input apparatus of the resistive type that is thinner and more durable is provided. The apparatus includes a first substrate having a conductive film on which a plurality of slits are formed in stripes, and a second substrate spaced apart from the first substrate at a fixed distance to face the surface of the first substrate implementing the conductive film. This second substrate has a conductive film formed on the surface facing the conductive film of the first substrate. A driving voltage is applied between two predetermined points on the conductive film formed on the first substrate. An electric potential of the conductive film formed on the second substrate is detected when the two conductive films come into contact.

  • Patent number: 6909425
    Abstract: Laser etching is used to form channels which divides a conductive film adhered on a board of a touch panel into a plurality of regions of desired form. A conductive film damage preventing element is attached on the board of the moving-side panel of a pair of panels or the double-faced tape to join them at their perimeters, to prevent damage by the edge of the double-faced tape. A re-usable adhesive layer having 90-degree peel off power of 5 g to 500 g/25 mm is used to adhere optical material on a surface of the panel.
