摘要:
A capacitive touch sensor includes an array of electrode elements, each electrode element including a drive electrode and a sense electrode, the drive electrode and the sense electrode forming at least one mutual coupling capacitor in each electrode element. A controller is operatively coupled to the array of electrode elements, the controller configured to measure the at least one mutual coupling capacitance over at least one measurement period. In addition, excitation signals applied during the at least one measurement period are balanced to reduce the effect of baseline capacitance.
