PROBLEM TO BE SOLVED: To provide an addressing mechanism for charging and discharging quasi-capacitive elements in an X-Y matrix. SOLUTION: The addressing mechanism may be configured to toggle a resistor-capacitor (RC) time constant between large and small values such as by opening or closing a circuit to a low impedance resistor (logic bit 0) disposed in parallel with a higher impedance in-line resistor (logic bit 1). Elements (102) in X-Y matrix can be addressed and controlled. The X-Y matrix may be composed of a plurality of "rows" and "columns" of conductors. Crosstalk which may be caused along columns and rows (100 and 101) may be curtailed by using either hysteresis management or global control of the impedance of the row. The resulting control obviates the need for active devices at each matrix element to perform the switching functions. COPYRIGHT: (C)2011,JPO&INPIT
