Patent number: 7404642Abstract: An autostereoscopic display having an improved 2D/3D mode switchable structure, including a display device to display an image, and a parallax barrier unit to transmit all incident light in a 2D mode and to separate a left-eye image and a right-eye image by forming a barrier in a 3D mode. The parallax barrier unit includes a polarizer to transmit light having a predetermined polarizer polarization direction, a first plane array including first and second birefringent elements, which change a polarization direction of light transmitted through the polarizer into a first direction and a second direction opposite to the first direction, respectively, and a second plane array including third and fourth birefringent elements, which change a polarization direction of light transmitted through the first plane array into a third direction and a fourth direction, that is opposite from the third direction, respectively.Type: GrantFiled: October 27, 2005Date of Patent: July 29, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Sergey Shestak, Dae-sik Kim

Patent number: 7404643Abstract: A projector has an illumination system, an electro-optical modulator, a projection optical system, and a scanning system. The illumination system has a light source, a first lens array, a second lens array, a polarization conversion element and a superposing lens. The polarization conversion element includes a polarized light separating element and a phase plate. The polarized light separating element includes a plurality of polarized light separating prisms each of which has a polarized light separating surface and a reflection surface. The plurality of polarized light separating prisms are arranged along the one direction, and polarized light separating surfaces in the polarized light separating prisms at both ends of the polarized light separating element in one direction are constituted so as to reflect the luminous flux involving the second polarized light component in a direction approaching the illumination optical axis.Type: GrantFiled: July 11, 2005Date of Patent: July 29, 2008Assignee: Seiko Epson CorporationInventor: Koichi Akiyama

Patent number: 7404644Abstract: A time-sequential colour projector comprises a pixellated light valve (2), such as a liquid crystal device, and a plurality of light sources (30, 31, 32). The light sources (30, 31, 32) direct light on different sets of pixels of the light valve (2) via an optical system (1), such as a lens array, which focuses the light on pixels of the light valve (2). At least two of the light sources (30, 31, 32) are multiple colour light sources and the multiple colour light sources emit different colour components during each set of frames making up a complete image frame.Type: GrantFiled: May 12, 2005Date of Patent: July 29, 2008Assignee: Sharp Kabushiki KaishaInventors: Allan Evans, Grant Bourhill, Marina V.

Patent number: 7404645Abstract: Image processing enhances display quality by controlling both the image modulator and the light sources. The image processing system utilizes a combination of user inputs, system configuration, design information, sensor feedback, pixel modulation information, and lighting control information to characterize the display environment on a per pixel basis. This per pixel characterization information is combined with one or more frames of the incoming real time display data. The image processing system processes each incoming pixel and produces a modified corresponding output pixel. Each pixel of each frame is processed accordingly. The image processing system also produces control information for the light sources. The light source control information can control individual lamps, tubes or LEDs, or can control a block or subset of the light sources. The resulting display has improved image consistency, enhanced color gamut, higher dynamic range and is better able to portray high motion content.Type: GrantFiled: October 21, 2005Date of Patent: July 29, 2008Assignee: Digital Display Innovations, LLCInventor: Neal D.

Patent number: 7404646Abstract: A projection lens apparatus includes a plurality of lenses, for enlarging and projecting, onto a screen, an original image displayed on an image generation source. The plurality of lenses are arranged, beginning with the lens nearest the screen, as first to sixth lens groups. The fourth lens group includes one meniscus lens that has a positive refracting power and has a concave lens surface directed toward the screen. The concave lens surface of the meniscus lens included in the fourth group lens has a curvature in the vicinity of an outer portion of the concave lens surface that is smaller than a curvature in a predetermined area of the concave lens surface defined between a light axis of the concave lens surface of the meniscus lens and the smaller curvature of the concave lens surface in the vicinity of the outer portion of the concave lens surface.Type: GrantFiled: February 18, 2005Date of Patent: July 29, 2008Assignee: Hitachi, Ltd.Inventors: Yuriko Inadachi, Shuji Kato, Hidehiro Ikeda, Naoyuki Ogura, Koji Hirata

Patent number: 7404649Abstract: The invention relates to devices configured and adapted to give a fluid stream the appearance of being lighted. Different colors of light, such as those provided from LEDs, may be used to generate an aesthetically pleasing effect of flowing colored fluid. In some embodiments, the fluid illumination may be accomplished by a light source directed towards a fluid stream from an external angle, for example. Alternatively, the light source may be pointed in the direction of the fluid stream, lighting it substantially internally. In yet other embodiments, the fluid illumination may be enhanced with the employment of reflective surfaces that bounce light around and through the fluid stream. To increase the appearance of being lighted, the reflective fluid surface area may be increased by generating turbulent flow. In certain embodiments, turbulent flow is achieved with the use of a separator to separate a single fluid stream into a plurality of micro-streams.Type: GrantFiled: September 20, 2006Date of Patent: July 29, 2008Assignee: Illinois Tool Works Inc.Inventors: Anatoly Gosis, David R.
