A touch panel includes a first substrate, a second substrate disposed facing the first substrate, a first conductive layer formed on one surface of the first substrate, a second conductive layer formed on a surface of the second substrate that faces the first substrate, an insulating layer disposed between the first conductive layer and the second conductive layer, and a decorative layer disposed between the first conductive layer and the insulating layer. The decorative layer is electrically conductive and is disposed along an outer periphery of the first substrate. The insulating layer has a through-hole that extends from the decorative layer to the second conductive layer.

Touch panel

A touch panel including: a substrate that includes an operation surface and a transparent conductive film formed opposite to the operation surface; a wiring pattern that is disposed below the transparent conductive film; and a decorative layer that is disposed between the transparent conductive film and the wiring pattern, and is composed of a chromatic color conductive ink which conducts the transparent conductive film and the wiring pattern.

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.

Coordinate detection apparatus

A touch panel includes a first substrate having a first conductive film formed on a surface thereof, a second substrate disposed to face the first substrate on a same side thereof as the first conductive film, the second substrate having a second conductive film formed on a surface thereof facing toward the first substrate, a decorative layer formed on the first conductive film on a surface thereof facing toward the second substrate, the decorative layer being formed along a perimeter of the first substrate, a first wire formed on the decorative layer on a surface thereof facing toward the second substrate, a first insulating layer laminated to the first wire, a second wire formed on the second conductive film on a surface thereof facing toward the first substrate, and a second insulating layer laminated to the second wire.

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.

Input apparatus

A touch panel that includes a polarizing plate, and used as an input device of a display unit of a personal computer, a word processor, an electronic notebook and the like is structured by one or more films that have a low heat contraction coefficient and a low water absorption coefficient, which remarkably suppress occurrence of concave deformations of the polarizing plate after exposure to a high temperature and soaking in water, avoiding short circuits.

Touch panel and an input device equipped therewith

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.
