Abstract
A touch sensor panel can include a silver nanowire touch electrodes formed in a silver nanowire layer on the substrate. In some examples, the touch sensor panel can include one or more anticorrosion layers to protect silver nanowire layer from ionization. In some examples, the silver nanowires include electrochemically stable outer shells that protect the silver nanowires from ionization. Additionally or alternatively, the touch sensor panel can including one or more anti-static layers to protect against electrostatic discharge (ESD). Additionally or alternatively, one or more anticorrosion layers and/or one or more antistatic layers can be formed with a passivation layer therebetween. The passivation layer, one or more anticorrosion layers and/or one or more antistatic layers can then be laminated to the silver nanowire layer to prevent corrosion and/or ESD events in the silver nanowire layer during the fabrication of the touch sensor panel.
