Abstract: A field emission device (100) includes an electroplated structure (122) and an electron emitter (118). Electroplated structure (122) includes a base (124), which is disposed proximate to electron emitter (118) and is made from the same material from which electron emitter (118) is made. Electroplated structure (122) further includes an electroplating electrode (126), which is disposed on base (124), and an electroplated layer (128), which is disposed on electroplating electrode (126). A method for fabricating field emission device (100) includes a step of forming electron emitter (118) and further includes a step of forming base (124) during the step of forming electron emitter (118). The method further includes a step of completely encapsulating electron emitter (118) prior to a step of forming electroplated layer (128).

Abstract: A field emission display (400) includes a cathode plate (410), an anode plate (430), and a mechanical support/getter assembly (300) being disposed between the cathode plate (410) and the anode plate (430). The mechanical support/getter assembly (300) includes a unitary spacer-frame assembly (310) made from a photosensitive glass. A method for fabricating the mechanical support/getter assembly (300) includes the steps of: selectively exposing inter-spacer regions (110) and a getter frame region (120) of a layer (100) of the photosensitive glass to UV radiation, heating the layer (100) to crystallize the UV-exposed regions, and removing the crystallized inter-spacer regions (110) and partially removing the crystallized getter frame regions by contacting the layer (100) with an acid, thereby forming spacer ribs (314) and a getter land (322). The method further includes providing a getter frame (320) on the spacer land (322).

Abstract: A sealing composition (134) includes about 85-95 wt. % glass frit, about 2-8 wt. % butyl carbitol acetate, about 2-8 wt. % alpha-terpineol, about 0.05-0.8 wt. % ester alcohol, and about 0.05-0.8 wt. % low molecular weight ethyl cellulose binder. A method for fabricating an apparatus (100) includes the steps of applying the sealing composition (134) to a portion (132) of the apparatus (100), removing the butyl carbitol acetate, the alpha-terpineol, and the ester alcohol, removing the binder, and heating the glass frit to a sealing temperature of the glass frit.
