ABSTRACT:
A transparency viewing device including a faceplate adapted for mounting at least one transparency thereon, a passive matrix LCD array comprising a plurality of row electrodes and a plurality of column electrodes separated by liquid crystal material, one of said plurality of electrodes having N electrodes and the other of said plurality of electrodes having M electrodes whereby the intersections of the row and column electrodes define a matrix of M.times.N pixel elements arranged in rows and columns, which pixels are excited by an RMS voltage difference between the two electrodes intersecting a pixel and a driver which electrifies the row and column electrodes such that at least one of a plurality n of the N electrodes or a plurality m of the M electrodes are identically electrified, wherein n.ltoreq.N and m.ltoreq.M.
