US 7,002,290 B2 · Carbon cathode of a field emission display with integrated isolation barrier and support on substrate

Abstract

A cathode plate of a field emission display comprising a cathode substrate of the field emission display and a plurality of linear isolation barriers each having a length and a thickness and attached to a top surface of the cathode substrate. The plurality of linear isolation barriers are spaced at intervals such that electron emitter lines can be formed between respective ones of the plurality of linear isolation barriers. In one embodiment, the linear isolation barriers comprise ribs attached to the top surface of the cathode substrate. In some embodiments, the linear isolation barriers are adapted to contact gate wires of a gate frame of the field emission display positioned above the cathode substrate to dampen driving frequency vibrations in the gate wires.

A cathode plate of a field emission display comprising:

a cathode substrate of the field emission display;
a plurality of linear isolation barriers each having a length and a thickness and attached to a top surface of the cathode substrate, wherein the plurality of linear isolation barriers are spaced at intervals such that electron emitter lines can be formed between respective ones of the plurality of linear isolation barriers, wherein the thickness is defined in a direction between the cathode substrate and an anode substrate and is configured to be less than a separation distance between the cathode substrate and the anode substrate;
and
gate wires extending over the plurality of linear isolation barriers such that portions of the plurality of linear isolation barriers contact the gate wires and dampen vibrations in the gate wires from a driving frequency.
