Claim 14:
15. The apparatus of claim 14, further comprising:
a signal source;
in-phase circuitry coupled to the signal source and to generate the in-phase drive signal;
opposite-phase circuitry coupled to the signal source and to generate the opposite-phase drive signal, and wherein the selection circuitry comprises:
a first set of multiplexers configured to couple to the first set of the transmitter electrodes at the first scanning stage, wherein each of the first set of transmitter electrodes is coupled to the in-phase circuitry, the opposite-phase circuitry, and the reference or ground potential; and
a second set of multiplexers configured to couple to the second set of the transmitter electrodes at the second scanning stage, wherein each of the second set of electrodes is coupled to the in-phase circuitry, the opposite-phase circuitry, and the reference or ground potential, and wherein the first and the second sets comprises a common electrode.
