20090213458 | FLOOR MOUNTED REAR PROJECTION SCREEN STRUCTURE AND DISPLAY SYSTEM - A floor mounted rear projection screen structure and display system is provided that includes a rear projection screen disposed in an opening defined in the floor and a projection system for projecting images onto the projection screen from beneath the screen. | 08-27-2009 |
20100053748 | REAR PROJECTION FABRIC, REAR PROJECTION SCREEN, AND REAR PROJECTION SYSTEM - Thin high-density fabrics are particularly suitable for super wide-angle rear projections that are accurate in every detail. Based on said recognition, the invention relates to a rear projection fabric ( | 03-04-2010 |
20100073767 | TRANSMISSION SCREEN FOR STEREOSCOPIC IMAGES - A transmission type screen for stereoscopic images having a transmission layer includes an incident surface having a gloss surface, a transmission layer having a refractive index less than 1.55, a transmissivity more than 60%, and an imaging surface having surface particle sizes of 40 to 400 mesh that avoids a hot spot. The imaging surface is formed on the final surface through which images are transmitted, so that the components operate in an organic fashion with respect to each other. The polarization degree of stereoscopic images is maximized thereby increasing the three-dimensional effect and the transmissivity, and enables viewers to view images clearly several times better than with a conventional screen. | 03-25-2010 |
20100195202 | DIFFUSING SCREEN - Various embodiments related to a rear projection display screen configured to reduce an intensity of light at a viewing angle at which the light is less likely to be viewed by a user are disclosed. One disclosed embodiment provides a diffusing screen comprising a sheet-like structure transparent to one or more wavelengths of light. The sheet-like structure has a viewing surface and comprises a diffusing pattern configured to create destructive interference of a selected wavelength of light traveling in a direction normal to a plane of the viewing surface of the screen. | 08-05-2010 |
20110043908 | PROJECTOR SCREEN EQUIPPED WITH MEANS FOR APPLYING VERTICAL AND HORIZONTAL TENSILE FORCES - A projection screen ( | 02-24-2011 |
20110164317 | CONTRAST-INCREASING REAR PROJECTION SCREEN - Rear projection device, rear projection screen and associated method for representing static or moving images, for improving the representation, particularly in ambient light, comprising at least one projection screen ( | 07-07-2011 |
20110216405 | TWO-WAY MIRROR SCREEN SYSTEM FOR ADVERTISEMENT - A two way mirror system usable for an advertisement device includes a half-mirror having a light transmission function and a reflection function. A logo plate in a shape of an engraving or pattern in relief or intaglio is provided on a front face thereof and a two way screen through which a rear projected image can be viewed from both a front and rear face is provided on a rear face thereof. A single advertising device thus provides a logo advertising using a logo plate and reflected outside light during the day and an image advertisement viewable outside during night time, with inside viewing with double the usual brightness of a reflecting screen. | 09-08-2011 |
20110249330 | REAR PROJECTION DOME - A seamless, shadowless, rear projection full dome imaging system comprising a 360° screen having a plurality of translucent screen sections, a rigid superstructure to which the screen sections are attached; clamping rings to hold the screen sections together; clamp arms to attach the screen sections to the superstructure, a transparent light guide attached to each clamping ring; adjacent screen sections being held between adjacent light guides by clamp arms; a plurality of projectors projecting a light image onto the rear of the screen sections; the light guides having a rear face angled perpendicular to the projected light; and a narrow front edge on the front side of the light guide. All surfaces of the light guides, except the rear face and the narrow front edge, are coated with a black opaque finish. | 10-13-2011 |
20120013977 | REAR PROJECTION SYSTEM, METHOD FOR PRODUCTION AND APPLICATION - The invention concerns a rear projection system in the form of a table consisting of at least one glass panel which has a diffusion coating containing hollow glass balls, whereas the hollow glass balls are arranged in a transparent or translucent binder matrix on the lower or upper surface of the glass panel and is illuminated from below with at least one projector having a projection field and that at least one projection image can be viewed by an observer at an observation angle of at least 176 degrees. | 01-19-2012 |
20120140319 | PROJECTOR SYSTEM AND DEVICE, RECORDING MEDIUM STORING POSITION DETECTION PROGRAM, AND IMAGE PROVIDING METHOD - A projector device includes an acquisition unit configured to acquire an image from an image pickup unit that picks up the image on a projection side of a transmissive type screen to which a display image is projected by a projector; a detection unit configured to detect a position where a luminance is changed on the acquired image; and an output unit configured to output the position on the acquired image where the change in luminance is detected. | 06-07-2012 |
20120182610 | Image System With Diffused Imaging Screen and Method of Manufacture - Provided are diffused but transmissive optical image projection screens and methods of their manufacture, including screens comprising acetal polymers such as polyoxymethylene. Such screens may be used in various applications, including but not limited electronic image display and control system comprising in various embodiments a microdisplay video projector that projects a high quality color image from a non-CRT image source onto a diffused but transmissive optical projection screen that is optically coupled with and viewable through a biocular adapted to this purpose. Systems are disclosed that are adapted to be mechanically coupled with a user to prevent relative movement between the biocular and the user, for instance in tactical applications. Closed-loop control electronics are provided for automatically controlling the brightness and chromaticity of the image. | 07-19-2012 |
20140340744 | OBJECTS FABRICATED WITH INTEGRAL AND CONTOURED REAR PROJECTION SUBSTRATES - A three dimensional (3D) object with a rear projection (RP) surface. The 3D object includes an RP element, which behaves as an RP substrate or surface. A structural portion of the 3D object has a first thickness, and the RP element has a second thickness that is less than about one half of the first thickness. The RP element is formed of a translucent white plastic for example, such that it is translucent to provide an RP element integrally formed with an adjacent structural element which is opaque with or without additional coating or treatment. | 11-20-2014 |
