Problems solved by technology

However, in the stage before the controller IC is connected, for example, in the assembly process and storage process of the light-transmitting conductive material in the stage where the controller IC is not connected, eliminate the electrostatic discharge caused by the peripheral wiring part. It is extremely difficult to generate a potential difference in the sensing part

Embodiment

[0046] Hereinafter, the examples related to the present invention will be described in detail. However, the present invention is not limited to the following examples unless the gist of the present invention is exceeded.

[0047] Fabrication of light-transmitting conductive material 1

[0048] As the support, a polyethylene terephthalate film with a thickness of 100 μm was used. In addition, the total light transmittance of this support was 91%.

[0049] Next, the physical development core layer coating solution was prepared according to the following formula, coated on the support, and dried to form the physical development core layer.

[0050] Preparation of palladium sulfide sol

[0051]

[0052] Liquid A and liquid B were mixed while stirring, and passed through a column filled with ion exchange resin after 30 minutes to obtain a palladium sulfide sol.

[0053] Preparation of coating solution for physical development core layer: the amount of silver salt photosensiti...

Abstract

This invention provides a light-transmitting electrically-conductive material that helps prevent decreases in yield when manufacturing touchscreens. Said light-transmitting electrically-conductive material has, on top of a support, light-transmitting sensor sections, a light-transmitting dummy section, a terminal section, a peripheral wiring section that electrically connects the sensor sections to the terminal section, and a grounding section. The peripheral wiring section contains parallel regions between adjacent peripheral wires, the grounding section contains parallel regions between adjacent grounding wires, and the minimum spacing (A) between peripheral wires in the parallel regions of the peripheral wiring section and the minimum spacing (B) between grounding wires in the parallel regions of the grounding section satisfy the relation A & gt; B.

Description

technical field [0001] The present invention relates to light-transmitting conductive materials suitable for use in capacitive touch panels and the like. Background technique [0002] In electronic devices such as personal digital assistants (PDAs), notebook computers, office automation equipment, medical equipment, or car navigation systems, in their display screens, touch panels are widely used as input means. [0003] In the touch panel, there are optical type, ultrasonic type, surface type capacitive type, projected type capacitive type, resistive film type, etc. depending on the method of position detection. In the resistive film type touch panel, as the light-transmitting electrode of the touch sensor, the light-transmitting conductive material and the glass with the light-transmitting conductive layer are arranged oppositely through the spacer, and the light-transmitting conductive material is measured by the current flowing through the light-transmitting conductive m...
