no. 1 approach

[0078] figure 1 It is a sectional view showing the input device 1 according to the first embodiment of the present invention. Such an input device 1 is mounted on a display unit of various electronic devices such as a portable device such as a mobile phone or a portable information terminal, a game device, a camera, and an imaging device in a state of being stacked and arranged on a display screen of a display device such as a liquid crystal panel. . The operator can see the image of the display device through the input device 1, and can directly touch various information displayed on the display screen with a finger or the like to perform an input operation.

[0079] Such as figure 1 As shown, the input device 1 is configured to have a sensor member 3 for detecting input position information and a protection member 2 for protecting the surface of the sensor member 3 . Furthermore, the sensor member 3 and the protective member 2 are bonded via the transparent filler 41 an...

no. 2 approach

[0111] Figure 7 It is a sectional view showing the input device 1 of the second embodiment. In the input device 1 of the second embodiment, as in the first embodiment, the protective member 2 and the sensor member 3 are integrally bonded via the transparent filler 41 and the adhesive layer 51 , and the sensor member 3 constitutes a capacitive touch sensor.

[0112] In the second embodiment, the first wiring pattern 35 is formed on the outer peripheral portion of the first sensor base material 31 , and the protective layer 42 covering the upper portion of the first wiring pattern 35 is formed. In the input device 1, in order to enlarge the light-transmitting area 21b, it is required to further reduce the wiring of the first wiring pattern 35, thereby narrowing the non-light-transmitting area 21c. Therefore, a protective layer 42 is provided on the first wiring pattern 35 to prevent disconnection or short circuit. The protective layer 42 can be formed by using the same resin ...

no. 3 approach

[0116] Figure 8 It is a sectional view showing the input device 1 of the third embodiment. Such as Figure 8 As shown, the sensor member 3 of the third embodiment constitutes a resistive film type touch sensor. In the sensor member 3 of the present embodiment, the first sensor base material 31 and the second sensor base material 32 are arranged to face each other with a space provided therebetween with a spacer 38 interposed therebetween. In addition, a first electrode pattern 33 and a second electrode pattern 34 are respectively formed on the opposing surfaces of the first sensor base material 31 and the second sensor base material 32 .

[0117] The first sensor substrate 31 arranged on the input surface side is a flexible film-like material deformable according to an input operation, and transparent resin such as PET (polyethylene terephthalate) is used. The thickness of the first sensor substrate 31 is about 100 μm to 200 μm, for example, it is formed with a thickness o...

Abstract

An input device includes a sensor member that detects input position information; and a protective member that protects the sensor member, wherein the protective member includes a window-shaped light-transmissive region transmitting light in the thickness direction, a transparent substrate having an input surface on a first surface, and a decorative layer disposed on a second first of the transparent substrate. The decorative layer is stacked on the transparent substrate so as to surround the light-transmissive region, and an inclined section is provided at the inner edge of the decorative layer; the transparent filler is stacked on the second surface of the transparent substrate to cover the light-transmissive region and the inclined section; and the sensor member and the protective member are bonded together with the adhesive layer disposed on the transparent filler and the decorative layer.

Description

technical field [0001] The present invention relates to an input device and a manufacturing method of the input device, in particular to an input device and a manufacturing method of the input device that do not generate air bubbles in a light-transmitting region and can be thinned. Background technique [0002] Conventionally, as a display unit of a portable electronic device or the like, a light-transmissive input device for coordinate input by directly operating a menu item or an object of a displayed image with a finger or the like is used. Since such an input device is stacked with a display device and incorporated into an electronic device, it is required to be thin and to have good visibility when viewing an image displayed on the display device. [0003] Figure 12 An input device 101 of a conventional example described in Patent Document 1 is shown. In the input device 101 , the upper light-transmitting substrate 131 and the lower light-transmitting substrate 132 a...
