Abstract
A passive matrix display has corrugated electrode edges to reduce zone visibility within a display system. A passive matrix display includes a first substrate and a second substrate; a liquid crystal layer positioned between the first and second substrates; a patterned electrode layer formed on the first substrate comprising a plurality of individual electrodes, wherein adjacent individual electrodes are separated by an electrode gap; and a second electrode layer formed on the second substrate. At least a portion of opposing edges of adjacent individual electrodes at the electrode gap include corrugations. The elements of the corrugations may be any suitable shapes and/or sizes as may be suitable for any particular application. The corrugations may be uniformly shaped or varying, symmetric or asymmetric about a horizontal axis, and/or may have a regular or irregular pattern. Another aspect is a display system including the enhanced passive matrix display that reduces zone visibility.
