摘要： Increasing the effective size of a touchpad while using a single controller IC, wherein a pseudo random pattern is used such that when a certain order of electrical signals is applied to the electrodes, the local electrical fields cancel or are very large in a first region while the electrical fields in a second region create a desired electrical field pattern, wherein when a finger makes contact in the second region a certain electrical signal is expected, wherein when a finger makes contact in the first region the electrical signal is unexpected, and wherein the difference between the electrical signals from the first region and the second region can be distinguished and thus the region in which the finger made contact can be determined.
