Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01J 902

US Classification:

445 24, 313309, 345 752

Abstract:

A method for operating a field emission device ( ) having an electron emitter ( ) includes the steps of providing an emitter-enhancing electrode ( ) proximate to electron emitter ( ), causing emitter-enhancing electrode ( ) to emit electrons, and causing the electrons emitted by emitter-enhancing electrode ( ) to be received by electron emitter ( ). A method for fabricating a field emission device ( ) includes the steps of forming a layer ( ) of dielectric material, forming emitter-enhancing electrode ( ) on layer ( ) of dielectric material, forming an enhanced-emission structure ( ) in emitter-enhancing electrode ( ), removing a portion of layer ( ) of dielectric material proximate to enhanced-emission structure ( ) to form a well ( ), and forming electron emitter ( ) within well ( ).

International Classification:

H01J 1304

US Classification:

313309, 313306

Abstract:

A field emission device ( ) includes an electron emitter ( ) and an emitter-enhancing electrode ( ) having an enhanced-emission structure ( ), which is disposed proximate to electron emitter ( ). Enhanced-emission structure ( ) is embodied by, for example, each of the following structures: a tapered portion ( ) of emitter-enhancing electrode ( ), an electron-emissive edge ( ) that is generally parallel to an axis ( ) of electron emitter ( ), a combination of a conductive layer ( ) and an electron-emissive layer ( ) that is disposed proximate to an edge ( ) of conductive layer ( ), and an electron-emissive layer ( ) having a thickness of less than about 500 angstroms.

International Classification:

F21V 700
H01J 516
H01K 126

US Classification:

313494

Abstract:

An optical correction layer for a light emitting apparatus having gaps in brightness at the light-emitting surface. The optical correction layer includes a plurality of optical correction regions centered over the gaps, and a plurality of optically transparent regions which overlay the remainder of the light-emitting surface. The optical correction regions include appropriately formed grooves which collect and redirect light adjacent the gap. The light is redirected to cover and effectively conceal the gap. The optically transparent regions permit light to travel through, without redirection.
