Appeal No. 97-1932
Application 08/028,047
Claims 1-5, 9-12 and 19-24 have been cancelled. Claims 6-8
have been allowed by the examiner.
The disclosed invention pertains to a field emission
display (FED) device. Such a device has a cathode emitter for
emitting electrons which are caused to impinge on an anode
layer by the application of an electric field. The anode
layer is attached to a transparent face plate having a
phosphor layer deposited thereon. The impingement of the
electrons on the phosphor layer causes light to be generated
which can be viewed through the face plate.
Representative claim 25 is reproduced as follows:
25. A field emission display (FED) device comprising:
a transparent face plate having a thin film phosphor
layer deposited thereon;
a conductive anode layer deposited on the phosphor layer;
at least one insulator layer serving as a spacer and
deposited on the anode layer;
a conductive extraction grid layer deposited upon the at
least one insulator layer, said conductive extraction grid
layer, said at least one insulator layer and said anode layer
being etched to form an array of vacuum space holes extending
to said phosphor layer;
an electron emitter layer molded in a form of an array of
lithographically-formed, sharply-pointed cathode structures, a
