Patent number: 6856089Abstract: The present invention relates to an organic electroluminescence element and the manufacturing method thereof comprising an anode, semiconductor layer, organic light-emitting medium, and a cathode, an organic light-emitting medium is located between the first electrode and the semiconductor layer comprising the non-monocrystal material and the second electrode is electrically connected to the edge section of the semiconductor layer when either one of the anode or cathode is designated to the first electrode and the other electrode to the second electrode. Because the first electrode and the second electrode are configured in such a manner not to be opposite to each other in this way, various electrode materials are able to be used and the light-emitting area is able to be increased, and therefore, the organic EL element with the luminous energy taken out to the outside and a manufacturing method that can efficiently obtain such organic EL element are able to be provided.Type: GrantFiled: January 2, 2001Date of Patent: February 15, 2005Assignee: Idemitsu Kosan Co., Ltd.Inventors: Chishio Hosokawa, Hisayuki Kawamura, Hiroaki Nakamura

Patent number: 6850007Abstract: A plasma display panel assembly includes electrodes and a dielectric layer covering the electrodes. The dielectric layer is formed of a low-melting-point glass, and the electrodes are formed of a metal containing a crystallized glass.

Patent number: 6844670Abstract: An organic EL element (100) emits light containing blue, green and red components. A blue color filter (420) transmits only the blue component. A green-converting member (340) converts the blue component to the green component, and a green color filter (440) transmits only the green component. A red-converting member (360) converts the blue component and the green component to the red component, and a red color filter (460) transmits only the red component. Since the respective color filters (420, 440 and 460) block unnecessary color components, the reproducibility of the respective color is improved. Since the luminescence of the organic EL element (100) contains the green component and the red component besides the blue component, white balance becomes good. It is therefore possible to provide a color luminous device from which improved light rays in the three primary colors can be emitted.Type: GrantFiled: October 30, 2002Date of Patent: January 18, 2005Assignee: Idemitsu Kosan Co., Ltd.Inventors: Hitoshi Kuma, Mitsuru Eida, Chishio Hosokawa

Patent number: 6825608Abstract: A field emission display device (1) includes a cathode plate (20), a resistive buffer (30) in contact with the cathode plate, a plurality of electron emitters (40) formed on the buffer, and an anode plate (50) spaced from the electron emitters. Each electron emitter includes a nano-rod first part (401) and a conical second part (402). The buffer and the nano-rods are made from silicon carbide (SiCX). The combined buffer and nano-rods has a gradient distribution of electrical resistivity such that highest electrical resistivity is nearest the cathode plate and lowest electrical resistivity is nearest-the anode plate. The conical parts are made from molybdenum. When emitting voltage is applied between the cathode and anode plates, electrons emitted from the electron emitters traverse the interspace region and are received by the anode plate. Because of the gradient distribution of electrical resistivity, only a very low emitting voltage is needed.Type: GrantFiled: July 12, 2002Date of Patent: November 30, 2004Assignee: Hon Hai Precision Ind. Co., Ltd.Inventor: Ga-Lane Chen

Patent number: 6815889Abstract: A high-pressure gas discharge lamp (HID [high intensity discharge] lamp) is described which is designed in particular so as to be free from mercury and suitable for use in automobile technology. To achieve improved lamp properties, in particular a substantially equal luminous efficacy compared with lamps of the same power and having a gas filling with mercury, as well as a burning voltage which is as high as possible, a geometry is proposed for the discharge space (2) which raises the temperature of the coldest spot in the lamp to such a degree that the light-generating substances can enter the gas phase to a sufficient extent also without mercury, and in particular in combination with the use of a metal halide as a voltage gradient generator.Type: GrantFiled: November 21, 2002Date of Patent: November 9, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Michael Haacke, Pieter Postma, Paul Hellwig, Juergen Schoeneich, Ralf Muckel

Patent number: 6809477Abstract: A fluorescent lamp (10) with improved life is formed by winding a coil (30) using first, second, and third mandrels (45, 46, 50), the third mandrel having a diameter of at least 1.0 mm. The coil is wound around the second mandrel to provide at least 80 turns per inch (TPI). The third mandrel is larger than in conventional coils, allowing about 50% more emitter material (32) than can be loaded on a conventional coil. This has been found to lead to substantially increased lamp life, about 50% longer for a diameter of 1.25 mm than for a coil with diameter of about 0.86 mm. Increasing the TPI of the second coil over that of a coil having a TPI of 60-70 also increases the lamp life by providing better retention of the emitter material. By combining both the increased third diameter with increased second coil TPI, lifetimes of about twice that of a corresponding conventional coil may be achieved.Type: GrantFiled: February 21, 2002Date of Patent: October 26, 2004Assignee: General Electric CompanyInventors: Thomas F. Soules, Igor V. Lisitsyn, Zsolt Buday
