Abstract: In some examples, a touch screen includes resistors between the touch electrodes and routing traces. In some examples, the resistors can include a transparent conductive material included in the touch electrodes of the touch screen. The resistors can be located in a border region of the touch screen that can surround an active area of the touch screen that can include the touch electrodes and display pixels of the touch screen, for example. In some examples, the resistors included in the touch screen can have different resistances from each other and the same outer dimensions as one another. The resistors can reduce the variation in resistance from channel to channel in the touch screen, which can improve touch screen performance, for example.

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.

Abstract: Transparent conductors including a silver layer with high transparency and low sheet resistance are described. In some examples, the silver layer can be located between two transparent conductive oxide layers. The transparent conductor can further include additional transparent conductive oxide layers, optical layers, and/or additional conductive layers (e.g., layers including ITO or another fully or partially transparent conductive material), for example. In some examples, transparent conductors including a silver layer can be included in a touch screen device. For example, one or more shielding layers or one or more touch electrodes can include transparent conductors with a silver layer. In some examples, the silver layer can improve transparency, sheet resistance, and/or infrared reflection characteristics of the transparent conductor.
