Abstract:
A field emission illumination device includes a sealed tubular body, an anode layer, a fluorescence layer and an electron emitting cathode electrode. The sealed tubular body has a light-permeable portion and the anode is formed on an inner surface of the light-permeable portion of the tubular body. The fluorescence layer is formed on the anode layer. The electron emitting cathode is positioned in the tubular body and includes at least one carbon nanotube yarn. In the illuminating process the energy in the field emission illumination device only undergoes transformation from electric energy to luminous energy, so the efficiency of the energy transformation is increased.

Abstract:
A field emission display including a first substrate and a second substrate opposing one another with a predetermined gap therebetween. An electron emission assembly is formed on the first substrate that emits electrons by the formation of an electric field. An illumination assembly is formed on the second substrate that realizes the display of images by the emitted electrons. A grid plate is mounted between the first and second substrates and functions to focus the emitted electrons. The grid plate includes a mask section having a plurality of apertures for passing the electrons, and supports mounted to one side of the mask section and extending in a direction toward the first substrate to rest on the same and support the mask section. The mask section and the supports are made of same material or two different materials.

Abstract:
A method for forming a carbon nanotube emitter by coating a photoresist on a substrate having an electrode already formed thereon, followed by patterning to form a photoresist dot on the electrode. The substrate is covered with a carbon nanotube paste that covers the photoresist dot. The carbon nanotube emitter is formed on the electrode by interdiffusion between the photoresist dot and the carbon nanotube paste through drying, and the carbon nanotube paste covering the carbon nanotube emitter is then removed.
Abstract:
An electron emitter includes a lower electrode formed on a glass substrate, an emitter section made of dielectric film formed on the lower electrode, and an upper electrode formed on the emitter section. A drive voltage for electron emission is applied between the upper electrode and the lower electrode. At least the upper electrode has a plurality of through regions through which the emitter section is exposed. The upper electrode has a surface which faces the emitter section in peripheral portions of the through regions and which is spaced from the emitter section.
Abstract:
The present invention broadly provides an improvement in a deuterium arc lamp having structure (e.g., anode 27, baffle 28, etc.) mounted on the distal end of an electrical conductor (26) within an elongated tubular glass envelope (21) in spaced relation to the side wall (22) of the envelope. The improvement broadly comprises spacer means (24), such as axially-spaced disk-like first and second members (32, 33), that operatively engage the structure, and that restrain transverse movement of such structure within the envelope.
Abstract:
A cathode-ray tube having a color-selecting electrode which is secured to a fluorescent glass panel by fitting fixing springs provided on the color-selecting electrode to fixing pins, respectively, which are provided on the fluorescent glass panel. The fixing springs have a shape factor K in the range of from 10 mm.sup.3 /kg to 100 mm.sup.3 /kg, the shape factor K being given byK=(thickness).times.(breadth).sup.2 .times.(height)/(length)/(weight of color-selecting electrode)Thus, it is possible to suppress the shift of the relative position of the fluorescent glass panel and the color-selecting electrode and minimize the incidence of product failures due to misregistration of colors.
Abstract:
An electric discharge tube or discharge lamp, in particular a flat-panel display screen, includes one or more low-temperature cathodes having a holder, which, optionally, is provided with a heating or cooling element, a conductive bottom layer which is applied to the holder, optionally a substrate with dispenser material, and a top coating of ultrafine particles having a nanostructure. The top coating has a surface layer consisting of an emitter complex formed from an emission material comprising several components. The cathodes have a high reliability and a long service life under a normal working load. The emission is stable, which contributes to a constant picture quality throughout the life of the discharge lamp or discharge tube. The discharge tubes or discharge lamps in accordance with the invention have short switching times and the advantage that their construction has been simplified and that their energy consumption is low. A method of manufacturing low-temperature cathodes in accordance with the invention is described.
