Patent number: 6777869Abstract: A transparent emissive display is created using a transparent anode and a transparent cathode so that images can be viewed from both sides of the field emission display panel. When the phosphor material emits the image, it can pass through the field emission material, if such a material is effectively made transparent by the manner in which it is deposited. The cathode conducting layer and the cathode substrate are thus also made transparent. Alternatively, multiple displays can be stacked together.Type: GrantFiled: April 9, 2003Date of Patent: August 17, 2004Assignee: SI Diamond Technology, Inc.Inventor: Igor Pavlovsky

Patent number: 6750461Abstract: By using a large area cathode, an electron source can be made that can irradiate a large area more uniformly and more efficiently than currently available devices. The electron emitter can be a carbon film cold cathode, a microtip or some other emitter. It can be patterned. The cathode can be assembled with electrodes for scanning the electron source.Type: GrantFiled: October 2, 2002Date of Patent: June 15, 2004Assignee: SI Diamond Technology, Inc.Inventors: Richard Lee Fink, Leif Thuesen

Patent number: 6739932Abstract: Embossed microstructures within a substrate are used to create narrow and deep holes within that substrate. A carbon nanotube solution or mixture is then deposited over this substrate with the embossed holes. Shaking or vibrating the substrate will then cause the carbon nanotubes to fall into each of the holes in such a way that all of the nanotubes within a hole will be substantially parallel to the long axis of the hole. This structure can then be combined with a gate electrode and an anode to create a field emission display device.Type: GrantFiled: June 6, 2002Date of Patent: May 25, 2004Assignee: SI Diamond Technology, Inc.Inventors: Zvi Yaniv, Richard Fink

Patent number: 6726335Abstract: An image projection system comprises an image projector, such as a film or television projector and a projection screen. The projection screen is fabricated of a substantially transparent material, such as glass or plastic. The screen of transparent material has one or more areas or portions formed therein which areas or portions may be made to be translucent upon the application of a stimulus. Once in a translucent condition, the projected image can be received and viewed on the translucent portion. A mirror can be positioned behind the projection screen so that a person can view the reflection of themselves in the mirror when the screen is transparent, and an image can be projected when the projection screen is made to be substantially translucent.Type: GrantFiled: February 21, 2003Date of Patent: April 27, 2004Assignee: SI Diamond Technology, Inc.Inventors: Zvi Yaniv, Michael C.

Patent number: 6692574Abstract: A carbon deposition chamber is provided with several advantages. The gas mixture used within the deposition process is expressed from tubing through three zones, which are each individually determined with needle valves. The substrate is permitted to rotate back-and-forth to permit more even deposition of carbon films onto the substrate. The heating filaments are permitted to expand and contract without breakage by permitting the electrode attached to one end of the filaments to move freely as the filaments change in length. The substrate and the heating filaments are cooled to a temperature to prevent carbonization by permitting a cooling fluid to be passed through tubing connected to these elements in a heat sink like manner.Type: GrantFiled: February 23, 2000Date of Patent: February 17, 2004Assignee: SI Diamond Technology, Inc.Inventor: Zhidan Li Tolt

Publication number: 20040017140Abstract: A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.Type: ApplicationFiled: February 21, 2003Publication date: January 29, 2004Applicant: Sl Diamond Technology, Inc.Inventors: Zvi Yaniv, Ronald Charles Robinder

Publication number: 20030197462Abstract: Field emission characteristics of carbon films are improved by changing the conditions of the growth of the films, by adding nitrogen, or substitutes to the nitrogen for hydrogen, in the carbon film growth process. Resulting field emission cathodes exhibit better field emission characteristics because of the increased concentration of nitrogen within the film.Type: ApplicationFiled: September 20, 2001Publication date: October 23, 2003Applicant: SI Diamond Technology, Inc.Inventors: Igor Pavlovsky, Richard Lee Fink, Zvi Yaniv

Patent number: 6630023Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing treatment of a substrate and then depositing the film. The treatment step creates nucleation and growth sites on the substrate for the film deposition process and promotes election emission of the deposited film. With this process, a patterned emission can be achieved without post-deposition processing of the film. A field emitter device can be manufactured with such a film.Type: GrantFiled: January 4, 2001Date of Patent: October 7, 2003Assignee: SI Diamond Technology, Inc.Inventors: Zhidan Li Tolt, Zvi Yaniv, Richard Lee Fink

Patent number: 6616284Abstract: A method and system for projecting an image. An image projection system may include a sensor configured to detect the presence of an observer within a proximity of a medium, e.g., screen, window. In response to the sensor detecting the presence of an observer within a proximity of the medium, one or more portions of the medium may be switched from a transparent state to a substantially translucent state. At a substantially concurrent time as switching the one or more portions of the medium to a substantially translucent state, an image may be projected onto such portion(s). Hence, an image may be displayed in response to detecting an observer within the proximity of the medium.Type: GrantFiled: June 28, 2002Date of Patent: September 9, 2003Assignee: SI Diamond Technology, Inc.Inventors: Zvi Yaniv, Michael C.

Patent number: 6613204Abstract: Before submitting a sample, including a first material layered upon a substrate, to an ion milling process, whereby a second material is sputtered onto the surface of the first material and the sample is then submitted to an etching process, an irregularity is formed on the surface of the first material. The overall process results in the formation of cones, or micro-tip structures, which may then be layered with a layer of low work function material, such as amorphous diamond. The irregularity in the surface of the first material may be formed by polishing, sandblasting, photolithography, or mechanical means such as scratching.Type: GrantFiled: February 7, 2001Date of Patent: September 2, 2003Assignee: SI Diamond Technology, Inc.Inventors: Chenggang Xie, Dean Joseph Eichman
