Patent number: 8456082Abstract: An extended area uniform light source providing uniform luminance is taught for displays and other applications where the light emission can be planar or have curvature. The uniform light source is achieved using a combination of a blue light-emitting electroluminescent layer and a highly stable inorganic photoluminescent color conversion layer to tailor the color spectrum of the emitted light. The invention thus encompasses the uniform light source, displays incorporating the uniform light sources as well of methods of making such light sources and displays.Type: GrantFiled: December 1, 2008Date of Patent: June 4, 2013Assignees: IFire IP Corporation, Sanyo Electric Co., Ltd.Inventors: James Alexander Robert Stiles, Hiroki Hamada, Isao Yoshida

Patent number: 7687792Abstract: The present invention provides a digital x-ray radiographic imaging system. The system is based on a photoconductive detector and an electro-optic light modulator, where the photoconductive detector layer absorbs x-rays that have passed through an object to form an exposure of the object. The absorbed x-rays create a static optical image, which is stored in the electro-optic light modulator, allowing the capture of the optical image to continue over longer time. The optical image is digitized using a scanning system and an external light source. The image is then processed and stored by a computer. After the optical image is recorded, an erasing mechanism is used to reset the system before a new exposure is made.Type: GrantFiled: February 9, 2007Date of Patent: March 30, 2010Assignee: Sunnybrook Health Sciences CentreInventors: John Alan Rowlands, Christie Ann Webster, Ivaylo Koprinarov, Peter Oakham, Stephen Germann, James Alexander Robert Stiles

Patent number: 7625501Abstract: An improved color-converting photoluminescent film that provides visible light emission in the red to green portion of the visible spectrum when excited by blue light. The color-converted photoluminescent film of the invention is patternable and has improved luminous efficiency and stability and is suitable for use in electroluminescent displays. The film comprises a mixture of a clear UV curable resin and photo-initiator which does not absorb blue light; and fluorescent pigment particles, wherein a molecular additive is optionally provided in to either or both of the pigment particles and curable resin. The mixture is screen printed onto a substrate to form a film and UV cured.Type: GrantFiled: May 17, 2005Date of Patent: December 1, 2009Assignee: Ifire IP CorporationInventors: Maizhi Yang, John Wesley Moore, Abdul M.
