Appeal No. 1997-3728
Application No. 08/323,311
BACKGROUND
The invention is directed to a process for manufacturing an active matrix electro-optic display
device, for use in an apparatus such as a color projection television. Claim 6 is reproduced below.
6. A method of forming an active matrix electro-optic display device comprising a pair of walls, at
least one of which is optically transparent, an array of pixel electrodes, an array of switches associated
with the pixel electrodes, an array of row and column electrodes interconnecting the array of switches
and pixel electrodes, and an array of storage capacitors, each storage capacitor connected to a pixel
electrode of the array of pixel electrodes, the arrays arranged on the inner surface of one of the walls, a
counter electrode on the inner surface of the other wall, and an electro-optic material filling the space
between the walls, the method comprising the steps of:
a) forming an array of islands of a conductive material,
b) forming a layer of a dielectric material on each island of the array of islands,
c) forming the array of row electrodes on the array of islands having the dielectric layers, to
thereby form the array of storage capacitors,
d) forming the array of pixel electrodes so that each pixel is located adjacent to a storage
capacitor, and
e) electrically connecting each of the islands to an adjacent pixel electrode.
