ABSTRACT:
An electrode configuration for reducing contact density in matrix-addressed display panels includes a first set of electrodes having termination points for connection to external driving electronics situated near the edge of a supporting substrate, and a second set of electrodes alternately interleaved among said first set having termination points spaced inwardly from the substrate's edge. An insulating film covers the termination points of the second plurality of electrodes and bond pads placed atop the insulating film are connected to the electrodes by leads. This insulates the second plurality of electrodes from a possible short circuit caused by random or one-on-one interconnects that bridge areas in the gaps between the electrodes.
