ABSTRACT:
An electronic display device comprises a display panel superposed on a printed circuit board with electrodes being disposed on the facing surfaces of both the display panel and the printed circuit board. An electrically conductive rubber connector electrically interconnects the electrodes in a predetermined pattern. The rubber connector is electrically conductive only in the direction normal to the electrodes and is non-conductive in the transverse direction thereby preventing short-circuiting between the electrodes. The connector is comprised of alternate segments of electrically conductive rubber and electrically non-conductive rubber alternately disposed along the transverse direction and each extending in the direction normal to the electrodes between the electrodes for electrically connecting opposed ones of the electrodes on the facing major surface of the display panel and the printed circuit board.
