Process for implementing conductive tracing layout in touch panel
View Patent ↗The touch panel comprises two conductive substrates arranged in parallel and secured to each other with a gap existing between the conductive substrates The process for implementing a conductive tracing layout in a touch panel includes steps of forming a first conductive layer on at least one of the conductive substrates; forming a first photo-resist layer on the first conductive layer; removing a specified portion of the first photo-resist layer to form a first specified mask on a specified portion of the first conductive layer; and removing the first conductive layer except the specified portion of the first conductive layer to form a first conductive tracing layout.
1. A process for implementing a conductive tracing layout in a touch panel, comprising steps of:
providing two conductive substrates of said touch panel;
forming a first conductive layer on at least one of said conductive substrates;
