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.
