| 20110075117 | PROJECTION DISPLAY DEVICE - A projection display device includes a light source; an optical system which modulates light from the light source, and emits the modulated light; a projecting portion which enlarges and projects the light emitted from the optical system; a cabinet which houses the light source, the optical system, and the projecting portion; an opening which is formed in one surface of the cabinet to allow mounting or dismounting of an optical component constituting the optical system, or the light source; a cover which covers the opening; and a holding portion which holds the cover in such a manner that the cover is allowed to slide in a direction along the one surface. | 03-31-2011 |
| 20110075110 | PROJECTION DISPLAY DEVICE - A projection display device includes a light source having a light emitting portion, a reflector which reflects light emitted from the light emitting portion, and a fixing portion which fixedly mounts the light emitting portion with respect to the reflector. The device further includes a first air supply portion and a second air supply portion which supply a cooling air; a first air drawing portion which separates the cooling air from the first air supply portion into streams of the cooling air to guide one of the streams of the cooling air into an interior of the reflector in a first direction and to guide the other of the streams of the cooling air to the fixing portion in a second direction; and a second air drawing portion which separates the cooling air from the second air supply portion into streams of the cooling air to guide one of the streams of the cooling air into the interior of the reflector in a third direction and to guide the other of the streams of the cooling air to the fixing portion in a fourth direction. | 03-31-2011 |
| 20110075109 | PROJECTION DISPLAY DEVICE - The projection display device includes an imager unit which modulates light from a light source, and a cooling device which cools the imager unit. In this arrangement, the imager unit includes a red imager which modulates light in a red wavelength band, a green imager which modulates light in a green wavelength band, and a blue imager which modulates light in a blue wavelength band. Further, the cooling device includes cooling fans which supply a cooling air to the imager unit. The cooling device is configured in such a manner that at least one of the cooling fans is provided for each of the red imager, the green imager, and the blue imager, and a plurality of the cooling fans is provided for at least the green imager. | 03-31-2011 |
| 20100033402 | Multiple Image Display Device And Image Display Device - In a multiple image display device that is provided with a plurality of image display devices and that displays a single input image, the image display devices each divide the input image into division images that are individually displayed on the image display devices, and enlarge and display them. In particular, the image display device provided in an edge portion of the multiple image display device enlarges the division image toward a side opposite from the side of the edge portion. In this way, the edge portion of the input image is displayed on the multiple image display. | 02-11-2010 |
| 20090119707 | AUTOMATIC CHANNEL SEARCH METHOD AND SYSTEM THEREOF - An automatic channel search system for use with a video display apparatus that has multiple video interfaces, in which all the channels of the multiple video interfaces are searched for a signaling channel carrying thereon a signal, and the signaling status and/or non-signaling status the respective channels is recorded. Utilizing this method, a channel search operation can be achieved in a significantly reduced time. Particularly, when there is one only one signaling channel found in the search, straightforward image processing is performed on the signal carried on that signaling channel to display the image of the signal. Further, when more than one signaling channel is found, the signaling channels are shown for the user to select one, and the signal of the selected channel is processed and displayed. | 05-07-2009 |
