MULTIPLEXING AND DEMULTIPLEXING TO REDUCE DRIVE AND SENSE ELECTRODES FOR SINGLE LAYER TOUCH SENSORS

A system and method for using data from a single-layer touch sensor to track a single object by using a coded stimulus drive pattern in order to multiplex data onto a sense electrode, measure the sense electrode, and then demultiplexing information from the measurement of the sense electrode in orde...

Zusammenfassung:A system and method for using data from a single-layer touch sensor to track a single object by using a coded stimulus drive pattern in order to multiplex data onto a sense electrode, measure the sense electrode, and then demultiplexing information from the measurement of the sense electrode in order to obtain position information regarding at least one object on the touch sensor.
