TAPERED MUTUAL CAPACITIVE SENSING PATTERN FOR SINGLE TOUCH

摘要

A system comprises a plurality of receiving electrode sets, each of the plurality of receiving electrodes being defined by a coupled intersecting diagonal bar; a plurality of sets of transmitting electrodes, each set of the transmitting electrodes having: at least a first electrode on a first side of its corresponding receiving electrode, and a second electrode on a second side of its corresponding receiving electrode; and a first AC signal generator to generate a signal on the plurality of electrode sets of transmitting electrodes to be received by the receiving electrodes.
