ABSTRACT:
A triode-type electrophoretic display includes a fluid-tight envelope for containing an electrophoretic fluid with suspended pigment particles and has a glass viewing window upon which has been deposited a plurality of parallel cathode members. A plurality of elongated insulator strips are interposed between and electrically insulate the cathode members from a plurality of parallel vertical grid members. Each of the strips support a corresponding grid member thereon a selected distance from the cathode members and tapers at a least one end such that the grid member is supported by the window at that end. The window provides a stable substrate for wire bonding the grid members to display driver circuitry.
