Abstract
Roll-to-roll processes for manufacturing touch sensors on a plastic base film are provided. The touch sensors can be deposited on the base film using various patterning techniques. One or more shorting bars can also be patterned onto the base film to couple together traces, such as drive lines, sense lines, conductive traces, and the like, of the touch sensor to prevent a potential difference from forming between traces due to static buildup during the manufacturing process. After the touch sensor is fully formed on the base film, the touch sensor can be removed from the base film using lithography or a physical cutting process. The removal process can separate the touch sensor from the one or more shorting bars, thereby uncoupling the traces of the touch sensor.
