METHOD OF PLASTIC TOUCH SENSOR PROCESS
First Claim
1. A method comprising:
- depositing a first conductive layer onto a substrate in a touch sensor region and a border region;
depositing a second conductive layer onto the first conductive layer in the border region; and
concurrently ablating the second conductive layer and the first conductive layer at removal locations in the border region to define border traces for providing off-panel connections to touch sensors in the touch sensor region.

Abstract
Methods of fabrication of a touch sensor panel using laser ablation are provided. The fabricated touch sensor panel can have touch sensors disposed on a surface of a substrate. A fabrication method can include depositing a first conductive layer onto a substrate in a touch sensor region and a border region, depositing a second conductive layer onto the first conductive layer in the border region, and ablating the second conductive layer at removal locations in the border region to define border traces for providing off-panel connections to touch sensors in the touch sensor region. This fabrication method can advantageously provide touch sensors in a fabrication process with high throughput using low cost material and equipment.
