Abstract:
A touch sensor panel configured to switch between a mutual capacitance near field sensing architecture and a self-capacitance far field sensing architecture. The touch sensor panel includes circuitry that can switch the configuration of touch electrodes to act as either drive lines in a mutual capacitance configuration or as sense electrodes in a self-capacitance configuration. The touch sensor panel also includes circuitry that can switch the configuration of touch electrodes to act as either sense lines in a mutual capacitance configuration or a sense electrode in a self-capacitance configuration.
