Embodiment approach 1

[0085] The capacitive input device 1 according to the embodiment of the present invention is as follows: figure 1 As shown, it is constituted by being combined with the image display device 2 , thereby serving as the input device 100 . The input device 100 includes at least a capacitive input device 1 , an image display device 2 , and a flexible flat cable 3 . In the input device 100, the capacitive input device 1 is disposed so as to overlap with the visual side of the image display device 2, that is, the side on which the user operates, and the surface of the capacitive input device 1 is equipped with a device for the operator to operate. An input unit 1a for inputting an operation, and an output unit 1b for outputting a signal from the input unit 1a to the outside.

[0086] Furthermore, a flexible flat cable 3 for outputting an input signal is connected to the output unit 1 b of the capacitive input device 1 . The flexible flat cable 3 is connected to an unillustrated de...

Embodiment approach 2

[0165] Capacitive input device 1 according to Embodiment 2 of the present invention is the same as Embodiment 1 ( image 3 as well as Figure 4 ) the same material to form the corresponding films, and then use the same film-forming method to form the films. Below, refer to Figure 5 as well as Figure 6 Compared with Embodiment 1, differences will be described in detail.

[0166] Figure 5 It is an explanatory diagram enlarging a part of the schematic diagram of the capacitive input device 1 according to Embodiment 2, Figure 6 is equivalent to Figure 5 A schematic cross-sectional view of the B-B line.

[0167] exist Figure 5 Among them, the first transparent conductive films 21c forming the spacer portion 21 are formed apart from each other, and on the other hand, the adjacent first transparent conductive films 21c are electrically connected to each other by the conductive member 51b. In addition, the second transparent conductive film 31d forming the spacer portion 3...

Abstract

Provided is a capacitance type input device having higher transparency and achieving lower power consumption. The capacitance type input device is provided with an input unit and an output unit on the same surface of a transparent substrate, wherein the output unit comprises a connection terminal for outputting a signal, and a wiring pattern for electrically connecting the input unit and the connection terminal. The input unit comprises a plurality of first electrode patterns composed of a plurality of first transparent conductive films arranged to be adjacent in the first direction, and a conductive member for electrically connecting the first transparent conductive films; and a second electrode pattern composed of a plurality of second transparent conductive films arranged to be adjacent in the second direction which intersects the first direction, and a connection unit arranged at the position intersecting with the conductive member of the first electrode pattern. The conductive member, the connection terminal, and the wiring pattern are formed by the same conductive film, and the conductive film is composed of a single metal layer, or a plurality of layers including at least one metal layer, and the conductive member is formed in the shape of a line.

Description

technical field [0001] The present invention relates to a capacitive input device and a manufacturing method thereof, and more particularly to a capacitive input device having high transparency and suppressed power consumption and a manufacturing method thereof.
