20090322972 | OPTICAL UNIT AND HEAD MOUNTED DISPLAY APPARATUS - An optical unit | 12-31-2009 |
20100073637 | ILLUMINATING DEVICE AND PROJECTION DISPLAY DEVICE - An illuminating device includes a plurality of light source portions for emitting light, a plurality of optical fibers for allowing incidence of the light emitted from the respective light source portions, and a bundling portion for bundling exit ends of the optical fibers. The light source portions or the optical fibers are constructed in such a manner that a flexure of each of the optical fibers is suppressed to mount the each optical fiber in a state close to a straight state. For instance, the light source portions are arranged in an arc shape, with a distance of each of the light source portions with respect to the bundling portion being set as the radius of the arc shape. In this arrangement the respective optical fibers are set to have lengths substantially equal to each other. | 03-25-2010 |
20100182573 | ILLUMINATING DEVICE AND PROJECTION DISPLAY DEVICE - An illuminating device includes a plurality of light source portions having a light source and condenser optics for condensing light from the light source, a plurality of optical fibers each connected to a corresponding one of the light source portions and into which the light from the corresponding condenser optics is incident, and a bundling portion for bundling the plurality of optical fibers. The plurality of light source portions are arranged on a plane approximately parallel to a bundling-central axis of the bundling portion, and the farther the light source portion is arranged from the bundling portion, the more the optical axis of the condenser optics is tilted toward the bundling portion from a direction vertical to the plane. | 07-22-2010 |
20100245781 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a housing case housing a solid light source, a light valve configured to modulate light emitted from the solid light source, and a projection unit configured to project light emitted from the light valve on a projection plane. The projection display apparatus includes a cable terminal provided on at least one of sidewalls forming both ends of the housing case in a horizontal direction parallel to the projection plane. | 09-30-2010 |
20100245783 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a housing case housing a plurality of light sources, a light valve, and a projection unit. The housing case has a projection-plane-side sidewall and a front-side sidewall, the projection-plane-side sidewall facing the placement surface, the front-side sidewall being provided on an opposite side to the projection-plane-side sidewall. The front-side sidewall has a protruding portion protruding outward of the housing case. | 09-30-2010 |
20100245787 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a housing case housing a light source unit, a light valve, a projection unit, and a cooling unit. A size of the housing case in an orthogonal direction to a projection plane is smaller than a size of the housing case in a horizontal direction parallel to the projection plane. The projection unit is arranged at substantially center of the housing case in the horizontal direction parallel to the projection plane. | 09-30-2010 |
20100245788 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a housing case housing a light source unit, a light valve, a projection unit, and a cooling unit. A size of the housing case in an orthogonal direction to a projection plane is smaller than a size of the housing case in a horizontal direction parallel to the projection plane. The projection unit is arranged at substantially center of the housing case in the horizontal direction parallel to the projection plane. | 09-30-2010 |
20110069286 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a housing case housing a plurality of light sources, a reflective light valve, and a projection unit. The housing case has a base plate and a ceiling plate. The ceiling plate is provided with a transmission area and a projection-plane-side shield plate, the transmission area being an area through which light emitted from the projection unit passes, the projection-plane-side shield plate being placed closer to the projection plane than the transmission area. The projection-plane-side shield plate is configured to shield unwanted light being other than light forming an image among light passed through the transmission area. | 03-24-2011 |
20110157555 | STEREOSCOPIC-IMAGE DISPLAY DEVICE - An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size. | 06-30-2011 |
20110216286 | ILLUMINATION DEVICE AND PROJECTION DISPLAY DEVICE - An illumination device includes: a plurality of light sources which emits light; a plurality of optical fibers into which the light from the light sources is entered; a bundle portion which bundles together output end portions of the plurality of optical fibers; and a cooling system which cools down at least a light output end plane of the bundle portion. | 09-08-2011 |
20120026070 | PROJECTION DISPLAY APPARATUS - A projection display apparatus displays an image on a projection surface in cooperation with a second projection display apparatus. The projection display apparatus includes: a detection unit that detects the position of the second projection display apparatus; and a switching unit that performs switching between a stack display mode and a tile display mode on the basis of the position of the second projection display apparatus. In the stack display mode, an image projected by the projection display apparatus and an image projected by the second projection display apparatus are displayed on a projection surface in a stacked manner. In the tile display mode, an image projected by the projection display apparatus and an image projected by the second projection display apparatus are displayed on a projection surface in a side-by-side manner. | 02-02-2012 |
