US Patent 12014003 Flexible self-capacitance and mutual capacitance touch sensing system architecture

A switching circuit is disclosed. The switching circuit can comprise a plurality of pixel mux blocks, each of the pixel mux blocks configured to be coupled to a respective touch node electrode on a touch sensor panel, and each of the pixel mux blocks including logic circuitry. The switching circuit can also comprise a plurality of signal lines configured to be coupled to sense circuitry, at least one of the signal lines configured to transmit a touch signal from one of the respective touch node electrodes to the sense circuitry. The logic circuitry in each pixel mux block of the plurality of pixel mux blocks can be configured to control the respective pixel mux block so as to selectively couple the respective pixel mux block to any one of the plurality of signal lines.
