Abstract:
A plasma addressed electro-optical display, comprising:a display panel having display electrodes;a plurality of circuit boards connected to said display panel;a drive substrate connected to said plurality of circuit boards so that said circuit boards are connected between said display panel and said drive substrate;connecting electrodes on said circuit boards connected between said drive substrate and said display electrodes on said display panel, said connecting electrodes having a predetermined pitch relative to one another, said connecting electrodes producing a first coupling capacitance between adjacent connecting electrodes as a result of said pitch, said connecting electrodes including outermost connecting electrodes adjacent edges of said circuit boards;a dummy electrode formed adjacent one of said outermost electrodes between said outermost electrode and said edge of said circuit board at said pitch relative to said outermost electrode so as to produce a second coupling capacitance between said dummy electrode and said outermost electrode substantially equal to said first coupling capacitance; andan electrical connection from said dummy electrode on one of said circuit boards to said outermost connecting electrode of a further one of said circuit boards.
