Abstract: Processes for manufacturing touch sensors with one or more guard traces to reduce the effect of moisture damage are provided. One example process can include forming one or more guard traces between an edge of the touch sensor and the metal traces that route the drive and sense lines to bond pads. The one or more guard traces can be uncoupled from the drive lines and sense lines to protect the inner metal traces from moisture damage. In some examples, ends of the one or more guard traces can be coupled to ground by copper. In other examples, ends of the one or more guard traces can be coupled to ground by indium tin oxide or the one or more guard traces can be coupled to ground by a strip of indium tin oxide. In yet other examples, the guard trace can be floating (e.g., not coupled to ground).

Abstract: Processes for reducing physical contact to sheets of base film in roll-to-roll processing of touch sensors are disclosed. In one example, the process includes the use of rollers having rings circumferentially extending away from the roller and operable to contact the sheets of base film. The rings can be configured to contact portions of the sheet of base film away from touch sensor areas of the base film. The rings can further be configured to prevent the sheets of base film from contacting a shaft of the rollers. In another example, a reduced strength vacuum seal can be formed between a photo mask and the sheet of base film to reduce the amount of force applied to a passivation layer of the sheet of base film.

Abstract: Roll-to-roll processes for manufacturing touch sensors using a sheet of patterned photoresist film are disclosed. The photoresist film can include a sheet of photoresist material, such as DFR, that has been patterned by removing portions of the photoresist film using a die or laser cutting technique. In some examples, the photoresist film can be patterned such that the patterned photoresist film can be laminated to a base film and used as an etching mask or a photoresist layer in a roll-to-roll manufacturing process. In this way, the patterned photoresist film can be used in place of conventional photoresist films in roll-to-roll processes, thereby obviating the need for subsequent exposure and development operations that would otherwise be performed when using conventional photoresist films. As a result, the chance that a defect is introduced into the touch sensors is reduced by reducing the number of operations performed in the roll-to-roll process.

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.
