Abstract:
A method for manufacturing electrodes of a glass panel for an information display, and a glass panel manufactured by the method is disclosed. The method comprises a step for mounting a glass substrate on an electrode member, a step for arranging an aluminum thin plate on the glass substrate, and a step for closely contacting the aluminum thin plate on the glass substrate while maintaining a space between one side of the glass substrate and the other side of the aluminum thin plate in a vacuum state. Expensive facilities for sintering electrodes are not needed, and various kinds of glass substrates and cheap aluminum electrodes can be used, so the manufacture cost of a front or back panel which is widely used as a glass panel for an information display can be significantly decreased.
Abstract:
The invention relates to a high- intensity discharge lamp (1) comprising a discharge vessel (2) and electrodes (4, 5) extending into said discharge vessel for emitting visible light. An electrically conductive screening (16), which is translucent to said emitted light, is provided on said discharge vessel. By applying the screening directly on the discharge vessel, the screening is brought closer to the source of EMI and, consequently, the EMI screening performance of the lamp is improved. The invention also relates to a headlight of a motorized vehicle provided with such a lamp, and a method of manufacturing such a lamp.
Abstract:
A fluorescent lamp (20) includes a glass bulb (30) that has mercury enclosed therein, and a phosphor layer (32) formed on an inner side of the glass bulb (30). The phosphor layer (32) includes three types of phosphor particles, which are red phosphor particles (32R), green phosphor particles (32G) and blue phosphor particles (32B) that are excited by ultraviolet radiation to emit red light, green light and blue light respectively. The blue phosphor particles (32B) and green phosphor particles (32G) have a property of absorbing ultraviolet radiation with a wavelength of 313 nm.
Abstract:
A Hop-FED structure has emitter areas (301, 302) on a substrate (300), and a hop-plate (303) disposed over the substrate (300) and emitter areas (301, 302) with a surface of the hop-plate (303) opposing the substrate (300) and emitter areas (301, 302). An electrically conductive layer (401) is formed on the surface of the hopplate (303), to dissipate charge build-up.
Abstract:
The present invention includes barrier coatings and methods for reducing or preventing chemical reaction between the discharge medium and arc tube wall material in discharge lamps. The barrier coatings comprise nitride layer exposed to the discharge medium formed from one or more of aluminum, boron, scandium, yttrium, or the lanthanides. In another aspect, the present invention includes methods of forming coatings on the inner wall of arc tubes by introducing two or more precursors into the arc tube chamber and pyrolitically reacting the precursors to form layers for the coating.
Abstract:
A composition and method of forming an internal neutral density filter (40) on a luminescent screen (22) assembly of a cathode ray tube (CRT) (10) is disclosed. The luminescent screen assembly is formed on an interior surface of a glass faceplate panel (12) of the CRT tube. The luminescent screen assembly includes a patterned light-absorbing matrix (23) that defines three sets of fields corresponding to one of a blue region, a green region and a red region. An internal neutral density filter is formed on the light-absorbing matrix. An array of blue, green and red color phosphors (42, 44, 46) is formed on the internal neutral density filter corresponding to one of the blue region, the green region and the red region defined in the light-absorbing matrix. The internal neutral density filter has a composition including a red pigment, a blue pigment and at least one non-pigmented oxide particle.
Abstract:
A method of manufacturing partial layers on lamp bulbs, in which method functional layers are provided in thin-film technology, and which method comprises at least the steps of: providing a temporary layer on that region of the lamp bulb which will have no functional layer in the operational state of the lamp, subsequently providing the functional layer on the entire surface of the lamp bulb, and detaching the temporary layer together with the functional layer present thereon.
Abstract:
The invention relates to a display device, in particular, cathode-ray tubes comprising: a display surface; an additional surface placed in front of the display surface, and; a device, which keeps the additional surface at a distance from the display surface and which provides a tight connection between the additional surface and the display surface. The device is characterized in that the space between the display surface and the additional surface is filled with a liquid.
