High Noise Immunity and High Spatial Resolution Mutual Capacitive Touch Panel

摘要

A mutual capacitive touch panel providing improved noise immunity and improved spatial resolution is described. The touch panel includes a drive line having a plurality of drive electrodes. The touch panel further includes a sense line arranged at an angle with respect to the drive line and the sense line having a plurality of sense electrodes, such that each of the plurality of sense electrodes overlies one of the plurality of drive electrodes. The touch panel is further configured such that a perimeter of each of the plurality of drive electrodes encompasses a perimeter of at least one of the plurality of sense electrodes.
