Problems solved by technology

Since the ITO film is rigid and fragile like a thin glass plate, there is a problem that when the ITO film is bent with a small radius of curvature R, cracks are generated and the conductive properties of the film are weakened
That is, there is a problem in that the ITO film is broken due to the pressure applied to the bent portion of the ITO film

Embodiment Construction

[0039] Now, the present invention will be described in detail with reference to the accompanying drawings showing specific embodiments thereof. FIG. 1 is a view of a touch panel according to an embodiment of the present invention.

[0040] As shown in FIG. 1 , the resistive film type touch panel 10 of the present embodiment includes: a fixed-side substrate (film) 11 which is a lower substrate to be attached to a liquid crystal panel; an operation-side substrate (film) 12, a substrate pressed by a finger, a pen, etc., and provided opposite to the fixed-side substrate 11; and an FPC connector 13, which electrically interconnects the two substrates 11, 12 to the main body of the device. The touch panel 10 is applied to a folding type information device 50 ( Figure 4), and integrally formed as one piece, having two input operation areas 14, 15 and a bending area (bending portion) 16 between the two input operation areas 14, 15. In this way, an operating region 15 is suitable fo...

Abstract

A touch panel includes a fixation side substrate and an operation side substrate disposed in opposition and adhered to each other, having a fixation side conductive film and an operation side conductive film respectively formed on opposing faces of the fixation side substrate and the operation side substrate, and being capable of detecting any contact point on the fixation side conductive film and the operation side conductive film as a 2-dimensional coordinate, wherein a bending section is formed between one end and the other end thereof, and wherein two input operation regions are defined and formed on both sides of the bending section.

Description

[0001] Cross References to Related Applications [0002] This application claims to be based on Japanese Patent Application No. 2007-093493 filed on March 30, 2007, Japanese Patent Application No. 2007-164246 filed on June 21, 2007, and Japanese Patent Application filed on November 27, 2007 Priority No. 2007-306418, the entire disclosure of which is hereby incorporated. technical field [0003] The present invention relates to a touch panel having a fixed-side substrate and an operation-side substrate disposed oppositely and attached to each other, and capable of detecting any contact point as two-dimensional coordinates within an input operation area inside a bezel. Background technique [0004] In recent years, the application of touch panels has become more and more popular, and touch panels have been increasingly mounted on portable information devices. In portable information devices such as mobile phones, small-sized game machines, etc., it is naturally desirable to h...
