Abstract:
A touch sensor panel is disclosed. In some examples, the touch sensor panel comprises a plurality of touch node electrodes. In some examples, the touch sensor panel comprises a touch controller configured to drive and sense the plurality of touch node electrodes in a fully bootstrapped configuration to obtain a fully bootstrapped touch image, drive and sense the plurality of touch node electrodes in a second configuration, different from the fully bootstrapped configuration, to obtain a second touch image, the second touch image including an effect of water on the touch sensor panel, and determine a final touch image based on the fully bootstrapped touch image and the second touch image, the final touch image not including the effect of the water on the touch sensor panel. In some examples, the second configuration comprises a mutual capacitance configuration. In some examples, the second configuration comprises a partially bootstrapped configuration.
