Abstract:
PROBLEM TO BE SOLVED: To provide a structure of an electron emission device having high packing density of an emitter and to provide its manufacturing process. SOLUTION: An electron emission property element suitable for a flat panel type display is manufactured by high packing density. An electronic emitter has a base supporting the structure. A lower side non-insulation region patterned into a shape forming a plurality of parallel lines is formed on an insulation material which is the base. An electron emission property filament is formed in a hole extending in an insulation layer provided on the lower side non-insulation region. Typically, a patterned non-insulation gate layer is provided on the insulation layer to form a gate control type device. Preferably, a position of an electron emission mechanism is delimited using a charged particle track. By using the charged particle track, the electron emission mechanism is greatly miniaturized and is arranged by bringing mutual interval close. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a field emission element with carbon nanotubes and a method for manufacturing the same, capable of preventing short-circuit between a gate electrode and a cathode. SOLUTION: The method for manufacturing the field emission element includes: a first step of performing vapor deposition of a protective layer on an insulation layer and a gate electrode such that the protective layer surrounds them and subsequently patterning the protective layer such that it is left only on the insulation layer and the gate electrode; a second step of coating a carbon nanotubes paste on the protective layer such that the paste is laminated on the protective layer with a well and an opening filled; a third step of irradiating light from a back side surface of a substrate so as to make the carbon nanotubes paste and the protective layer exposed and subsequently lifting off unexposed portions during development of the carbon nanotubes paste and the protective layer so as to form a carbon nanotubes column; and a fourth step of sintering the carbon nanotubes column so as to lower its height and subsequently performing surface treatment thereon so as to form a field emitting source, in which carbon nanotubes chips are aligned on a surface of the carbon nanotubes column.

Abstract:
An optical correction layer (800, 900, 50) for a light emitting apparatus having gaps (604, 806) in brightness at the light-emitting surface (204, 601). The optical correction layer (800, 900, 50) includes a plurality of optical correction regions (802, 902, 62) centered over the gaps (604, 806), and a plurality of optically transparent regions (804, 904, 57) which overlay the remainder of the light-emitting surface (204, 601). The optical correction regions (802, 902) include appropriately formed grooves (820, 822, 920) which collect and redirect light (816) adjacent the gap (604, 806). The light (816) is redirected to cover and effectively conceal the gap (604, 806). The optically transparent regions (804, 904, 57) permit light to travel through, without redirection.
