Abstract

An x-y-addressed imager assembly includes a common electrode having more than two electrical contact points disposed at selected intervals along each edge of the common electrode that corresponds to a lateral boundary of the imager assembly. The selected intervals are typically about equal in length and not greater than about 12% of the length of the edge of the common electrode. The multiple electrical contacts along the common electrode provide low impedance and low magnetic loop area for signals passing along the common electrode to readout and drive circuits.
