Abstract: Visibility of the metal mesh touch electrodes can be mitigated using one or more mitigation techniques. In some examples, the boundary between touch electrodes and/or the boundary between a touch electrode and a routing trace of another touch electrode and/or the boundary between two routing traces can be non-linear. In some examples, dummy cuts can be made within an area of a touch electrode region (e.g., while maintaining the same electrical potential for the touch electrode region). In some examples, notches can be made in the metal mesh. In some examples, the location of cuts and/or notches can be optimized to mitigate visibility of the metal mesh. In some examples, some or all of the visibility mitigations may be used in combination in a touch screen.

Abstract: A touch sensor panel is disclosed. In some examples, the touch sensor panel includes drive electrodes and sense electrodes, wherein the drive electrodes and sense electrodes form touch nodes. In some examples, touch nodes include differently-sized drive and/or sense electrodes, and changes to the size or quantity of reference or floating electrodes disposed within the drive and/or sense electrodes are used to substantially balance the areas of the drive and/or sense electrodes in a given touch node.
