Abstract: A touch sensor panel is disclosed. The touch sensor panel can include a plurality of touch nodes, the plurality of touch nodes including a first set of touch nodes and a second set of touch nodes, different from the first set of the touch nodes. In some examples, sense circuitry can be configured to, during a first scan, sense a first combined touch signal of the first set of the touch nodes, and during a second scan, sense a second combined touch signal of the second set of the touch nodes. A touch processor can be configured to determine a touch image at the plurality of touch nodes based on the first and second combined touch signals.

Abstract: Electrode configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of a touch sensor panel are disclosed. In some examples, electrodes associated with a more linear signal profile are correlated with lower wobble error. In some examples, electrodes can have projections which can interleave with projections of adjacent electrodes. In some configurations, projections of adjacent electrodes can be interleaved in one-dimension; in other configurations, projections of adjacent electrodes can be interleaved in two-dimensions. In some configurations, the width and length of one or more projections in an electrode can be selected based on a desired signal profile for that electrode.
