Abstract
An electrostatic display assembly including a plurality of channel shaped casings fixed to an insulating base plate into a line, each casing having a pair of side walls, a fixed electrode extending throughout the length of the casings therein, a resilient sheet electrode supported within each casing so that a pair of flaps of the sheet electrode extend upwards adjacent to the fixed electrode along the inner surface of each casing, and a thin layer of insulating material interposed between the outer surface of the fixed electrode and the inner surfaces of the resilient sheet electrodes, whereby upon the application of voltage between the fixed electrode and any one of the resilient sheet electrodes which are electrically independent of each other, that flaps of the sheet electrode are attracted to the surface of the fixed electrode and covers the same in part, changing the appearance of the assembly.
