Metal Electrode Films for Capacitive Touch Screens

Metallic films suitable for fine wiring

Overview

Fine metallic wiring is used for touch screen electrodes. We provide metallic films that can be easily processed and offer superior electro-conductive characteristics.

Features & Strengths

Point1 Optmized for fine processing via photolithography

Point2 We offer solution for conductor materials with an eye for electro-conductive characteristics, reliability and more

As increasingly fine patterns are used in display areas, the number of electrodes grows accordingly. To address this problem, we recommend the use of silver and aluminum conductor materials, in consideration of their resistance, etching properties, and reliability.

Specifications

A diverse variety of metal films

When considering resistance, etching properties, and reliability, we recommend the use of silver and aluminum conductor materials.

Silver varieties

We recommend APC-TR parts, as they are thought of as the most reliable.

Aluminum varieties

In consideration of reliability and comparative resistance, select modified neodymium (1wt%) parts. Lastly, in consideration of contact with ITO films, as well as improved surface resistance to alkalines, we recommend a structure that sandwiches different materials. In terms of materials, we recommend MAM parts, due to their etching properties, environmental properties, and reliability.
