Abstract:
A hybrid plasma semiconductor device has a thin and flexible semiconductor base layer. An emitter region is diffused into the base layer forming a pn-junction. An insulator layer is upon one side the base layer and emitter region. Base and emitter electrodes are isolated from each other by the insulator layer and electrically contact the base layer and emitter region through the insulator layer. A thin and flexible collector layer is upon an opposite side of the base layer. A microcavity is formed in the collector layer and is aligned with the emitter region. Collector electrodes are arranged to sustain a microplasma within the microcavity with application of voltage to the collector electrodes. A depth of the emitter region and a thickness of the base layer are set to define a predetermined thin portion of the base layer as a base region between the emitter region and the microcavity. Microplasma generated in the microcavity serves as a collector. Logic devices are provided in multiple sub collector and sub emitter microplasma devices formed in thin and flexible or not flexible semiconductor materials.
Abstract:
A segment display system (10) whereby ultraviolet energy is generated and contacted with fluorescent material coatings (78) to create electromagnetic wave generation within the visible bandwidth of the electromagnetic spectrum through fluorescent excitation of the fluorescent material coatings (78). Ultraviolet energy is generated from the ionization of metallic atoms from a metallic coating (42) coated to through opening sidewalls (40) of slots (38) forming the cathode mechanism (26). The slot through openings (38) are in registration with the fluorescent material coatings (78) mounted on a display panel member (80). Below the cathode mechanism (26) is a common anode element (62). Each of the metallic coatings (42) formed within each of the slot through openings (38) is coupled to an external electrical source as is the anode element (62). The segment display system (10) is formed into a monolithic structure which includes the internal chamber (64) within which an inert or combination of inert gases is introduced. Electrical energization of the cathode elements and the anode element (62) results in ionization of metal atoms emitted from the metallic coating (42). The ionization process provides for ultraviolet radiation which is directed to the fluorescent material coating (78). The coatings (78) are generally linearly extended and are formed into a predetermined pattern in order to provide information output responsive to a predetermined cathode element being energized in combination with the energization of the common anode element (62).
Abstract:
An improved lighting system (10) which in the preferred embodiment includes a cathode (12) having an external surface (34) being coated with a cathode outside film (40) for emitting electrons therefrom. A first anode (14) extends internal to the cathode (12) for heating the cathode (12) to thereby emit electrons from the external surface (34). A second anode (16) is positionally located external to the enclosed cathode (12) for accelerating the electrons emitted from the cathode external surface (34). A bulb member (18) encompasses the cathode (12), the first anode (14), and the second anode (16) in a hermetic type seal. The bulb member (18) has a predetermined gas composition contained therein with the gas composition atoms being ionized by the cathode emitted electrons. The gas composition ionized atoms radiate in the ultraviolet bandwidth of the electromagnetic spectrum. The bulb member (18) is coated with a fluorescent material (20) for intercepting the ultraviolet energy responsive to the ionization of the gas composition atoms. The fluorescent material (20) radiates in the visible bandwidth of the electromagnetic spectrum to give a visible light output.
Abstract:
A gaseous discharge display panel in which in order to display images of good quality with high brightness and high efficiency a discharge unit constituting of a picture element of the display panel is formed as an elongated fine section extending in parallel to the display plane and discharge is produced in the longitudinal direction of the discharge unit so as to display images with the aid of plane discharge. Particularly in order to display color images on the front and/or rear side of the discharge unit there is arranged an insulating sheet to which fluorescent materials are applied in such a manner that the fluorescent materials are opposed near a discharge plasma with a large area and an ultra-violet ray produced by the discharge can excite efficiently the fluorescent materials. The display panel is so constructed that luminescent light from the fluorescent materials having a large surface area can be inspected in the form of the reflected and transmitted light so as to increase the luminous brightness by several times compared with known display panels. Moreover, a cathode of the discharge unit is arranged at a position hidden from the fluorescent materials so as to prevent sputtered cathode materials due to ion bombardment from being applied to the fluorescent materials, so that the fluorescent materials are not blackened and thus the luminous brightness is not decreased.
Abstract:
The specification describes a flat panel gaseous discharge display device in which the display illumination is formed at least in part by luminescence resulting from excitation of an appropriate phosphor by low energy electrons drawn from a glow discharge. To provide scan, the discharge is either itself moving in stepwise fashion between discrete cells or is a secondary discharge primed by a scanning discharge and triggered by the display information signal. Varying the current through the phosphor produces gray scale. Illumination from the gaseous discharge may be mixed with the phosphor for color balance and increased brightness. The phosphor can be divided into color stripes with means for selective energization of the stripes to form a color display.
Abstract:
A flat-panel gas discharge display operable with either alternating or direct current is free of implosive forces because it operates at least at substantially atmospheric pressure. The display comprises a first set of conductors disposed on a transparent substrate and a second set crossing over the first set at a distance therefrom. An array of crosspoints is formed at each location where a conductor of the second set crosses over a conductor of the first set. A gas is contained in the space between the first and second sets of conductors at each crosspoint. The gas will undergo light emissive discharge when a voltage greater than or equal to the Paschen minimum firing voltage is applied at a crosspoint. Air may be used as the operative gas. The display is formed on a single substrate, and may be stacked with additional displays in lieu of one or more capping layers. At least one of the sets of conductors may be provided with an aperture at each of the crosspoints to facilitate viewing the discharge. A system incorporating the flat-panel display is presented. A suitably wired flat-panel structure may constitute a flat-panel plasma discharge lamp for lighting applications.
