Patent number: 7439672Abstract: The three-dimensional electroluminescence display comprises a main body (1) and an electroluminescence device (20). Said electroluminescence device (20) comprises a film (2) and an electroluminescent arrangement (10) which together form a whole. The surface of the film (2), facing the electroluminescent arrangement (10) is provided with the motifs (9) for display. The electroluminescent arrangement (10) comprises a front electrode (11) and a back electrode (12), between which a dielectric (13) is located. The front electrode (11) is provided with the layer which produces the motif (9) and is embodied in one piece with the same. A supply source (15) is arranged within the surface of the electroluminescence device (20), which contacts the electrodes (11,12) of the electroluminescence device (20).Type: GrantFiled: October 24, 2002Date of Patent: October 21, 2008Assignee: Lyttron Technology GmgHInventor: Emil Enz

Patent number: 7294966Abstract: An EL panel on a rigid substrate is thinned in selected areas, or overall, to provide a backlight for keypads and other applications that would otherwise require a more flexible panel or additional structure. Lamp materials are deposited on one side of a rigid substrate and then substrate material is ablated with a suitable tool, working from the opposite side of the substrate as the lamp materials. The depth of cut can be constant or variable, enabling one to tailor the flexibility of an area to the desired tactile response for a keypad or to provide clearance in close quarters. The invention is compatible with known process for making an EL panel.Type: GrantFiled: April 29, 2004Date of Patent: November 13, 2007Assignee: World Properties, Inc.Inventor: Rodney T. Eckersley

Publication number: 20070152576Abstract: An electroluminescent display device is fabricated by creating a generic electroluminescent base laminate or precursor containing an base electrode and an electroluminescent layer. A custom graphic arts film or precursor containing a graphic element and a corresponding electrode is also fabricated. The two precursors are then bonded together using an adhesive to create the customized EL display, so that only the sections of the electroluminescent display device that are associated with the corresponding electrode on the graphic arts film emit light.Type: ApplicationFiled: December 29, 2005Publication date: July 5, 2007Applicant: MOTOROLA, INC.Inventors: Krishna Kalyanasundaram, Daniel R.

Patent number: 7109661Abstract: An electroluminescent light emitting system, having an electroluminescent light-emitting layer containing electroluminescent light-emitting elements, one surface side of which receives an AC electric field forming material thereon; an electrode section including a first electrode layer with a predetermined first pattern and a second electrode layer with a predetermined second pattern, which are disposed relatively close to but electrically spaced from each other on another surface side of the electroluminescent light emitting layer; and a waterproof resin layer provided between at least one of the first electrode layer and the second electrode layer electrode section, and the electroluminescent light-emitting layer. The AC electric field forming material on the one surface side enables an AC electric field to be generated in the electroluminescent light-emitting layer with an AC voltage applied between the first electrode layer and the second electrode layer.Type: GrantFiled: May 29, 2003Date of Patent: September 19, 2006Assignee: Tomy Company, Ltd.Inventors: Kimitaka Watanabe, Hiroyuki Yamanaka

Patent number: 7088039Abstract: Certain materials are electroluminescent, and this electroluminescent effect has been used in the construction of backlights for displays. Such a backlight commonly consists of a transparent front layer (11) known as the substrate carrying over its rear face a transparent electrically-conductive film (12) forming the backlight's front electrode and covered by a layer of electroluminescent/phosphor material (13) over the rear face of which is a high-dielectric dielectric layer (16) bearing on its rear face a conductive film (17) forming the back electrode. The whole is positioned behind a mask (18) that defines whatever characters the display is to show. This use of a mask has some disadvantages, some of which can be overcome by utilizing an array of suitably shaped individual electrodes (21) instead of a continuous one; however, this itself has drawbacks, since the lead (22) to each electrode acts as an electrode in its own right, activating the phosphor to show faint but distracting additional illumination.Type: GrantFiled: March 15, 2004Date of Patent: August 8, 2006Assignee: Pelikon LimitedInventors: Christopher Barnardo, Richard Blakeney, Christopher James Newton Fryer, Frank Tyldesley

Patent number: 7077552Abstract: A lighting device unit which conducts illumination for forming an upward protrusion has a light source including a light emitting diode in which three light emitting chips are horizontally arranged, and a projection lens which projects an image of the light source toward the front of the lighting device as an inverted image. The inverted images of the light emitting chips of the light source formed respectively on a virtual vertical screen in front of the lighting device are horizontally shifted from one another. When a vehicle moves straight forward, the first light emitting chip is turned ON; when the vehicle turns leftward, the second light emitting chip is turned ON; and, when the vehicle turns rightward, the third light emitting chip is turned ON. The position where the upward protrusion is formed is horizontally moved to brightly illuminate the road surface in the traveling direction of the vehicle.Type: GrantFiled: April 20, 2004Date of Patent: July 18, 2006Assignee: Koito Manufacturing Co. Ltd.Inventor: Hiroyuki Ishida

Patent number: 7016264Abstract: A light emission and display device (for example, timepiece module) comprising an ultraviolet ray emitting element that emits ultraviolet rays, light emission areas that react to the ultraviolet rays to thereby emit the corresponding colored lights, and a pair of legs that connect in a stabilized manner the ultraviolet ray emitting element and a connection terminal of a circuit board in the light emission and display device. Each leg has a bend for adjusting the length and a bend angle of the leg between the ultraviolet ray emitting element and the connection terminal (FIG. 19).Type: GrantFiled: November 15, 2002Date of Patent: March 21, 2006Assignee: Casio Computer Co., Ltd.Inventors: Masato Ueno, Tadao Hirano, Shyuichi Machida, Mitsunobu Yatabe

Patent number: 6998774Abstract: An electroluminescent display has a transparent front-electrode, rear electrodes, and a layer of electroluminescent material located between the first and second electrodes. Conductive tracks are electrically connected to the rear electrodes and supply a driving voltage for the electroluminescent material to the rear electrodes. A backplane layer is provided between the electroluminescent material layer and the conductive tracks, and is electrically connected to the front electrode such that the potential difference across the electroluminescent material layer in the region of the conductive tracks is substantially zero. In this way, when the conductive track is supplying the driving voltage to the rear-electrodes, the electroluminescent material layer is not illuminated by an electric field between the conductive tracks and the front electrode. Gaps may be defined in the front electrode corresponding substantially to the location of the conductive tracks.Type: GrantFiled: May 22, 2000Date of Patent: February 14, 2006Assignee: Cambridge Consultants LimitedInventors: Christopher John Andrew Barnardo, Christopher James Newton Fryer
