Abstract
An electro-optic display having either variable-color or selectable-color capability is disclosed, with each having particularly efficient electrode patterns for achieving color control. Each implements a passive display utilizing an electro-optic material such as PLZT having one of these types of electrode patterns and aligned with an appropriate multi-colored filter. By applying D.C. control voltages to these sets of electrodes, which are sufficiently small to form unit cells, variable or selectable color is perceived. The patterns may be arranged in a sequence of any length or width, with the three-shutter pattern featuring no surface-mounted crossovers.
