Method of manufacturing a capacative touch sensor circuit using a roll-to-roll process to print a conductive microscopic pattern

摘要

Mutual capacitance touch sensor circuits are used in manufacturing displays, including touch screen displays, such as LED, LCD, plasma, 3D, and other displays used in computing as well as stationary and portable electronic devices. A flexographic printing process may be used, for example, in a roll to roll handling system to print geometric patterns on a substrate, for example, a flexible dielectric substrate. These patterns may then be coated with a conductive material by, for example, an electroless plating process.
