20120057136 | IMAGE DISPLAY APPARATUS - The present invention provides an image display apparatus that includes a case having an air inlet port and an exhaust port; a cooling air passage that is formed by connecting the air inlet port and the exhaust port; and an optical unit that is provided within the case. The optical unit includes a red color laser light source, a green color laser light source, and a blue color laser light source, and these laser light sources are positioned in the cooling air passage. Further, the image display apparatus has an air blower that cools the laser light sources of the respective colors by introducing air from the air inlet port and exhausting air from the exhaust port; and a lens that is provided on the light-emitting side of the laser light sources. The red color laser light source is positioned closer to an upstream side of the cooling air passage than the green color laser light source and the blue color laser light source. With this, the temperature of the red color laser light source apparatus is not increased by a long period of use, and thereby image quality deterioration is prevented. | 03-08-2012 |
20120057137 | IMAGE DISPLAY APPARATUS - Provided is an image display apparatus that has: a case distinguished into a plurality of regions and has a projection port; an image display apparatus main body that projects an image from the projection port; and a controller that electrically connects to the image display apparatus main body and to an external electronic device, and is positioned so as to straddle on the plurality of regions. The case has: a first region that houses a first portion of the controller and is held by the electronic device at least at one portion of the region; a second region positioned away from the electronic device so as to sandwich the first region and houses the image display apparatus main body; and a third region positioned away from the projection port and away from the electronic device so as to sandwich the first region, and houses a second portion of the controller. Therefore, the image display apparatus can be made compact to be installed within an electronic device. | 03-08-2012 |
20120062852 | IMAGE DISPLAY DEVICE - An image display device includes a housing that accommodates a plurality of laser light source devices that emit laser light of respective colors, a light modulator, a projection optical system and a controller, a movable body that is ejectable from and retractable into the housing and includes at least the projection optical system, a first switch that turns ON in a use state in which the movable body is ejected from the housing, and a second switch that turns ON in response to an operation of an operating portion by a user. The laser light is emitted from the plurality of laser light source devices when both of the first switch and the second switch turn ON. Accordingly, laser light is securely prevented from being emitted in a nonuse state by a switch erroneously turned ON. | 03-15-2012 |
20120092309 | IMAGE DISPLAY DEVICE AND INFORMATION PROCESSING DEVICE INCLUDING IT - It is a main object of the invention to provide an image display device and an information processing device that can be incorporated in the computer main body of a notebook computer, etc., and can project an image at any desired angle when the image is projected onto a screen. To accomplish the object, the invention provides an image display device including a first unit for storing an optical system for displaying an image on a screen and a second unit for storing a control board for controlling the optical system, electrically connecting to the first unit, and holding the first unit for rotation. The first and second units are housed in a housing space formed in an information processing device. When the image is projected onto the screen, the first unit is completely exposed from the information processing device and at least a part of the second unit is stored in the information processing device. When the image is not projected onto the screen, the first unit and the second unit are stored in the information processing device. | 04-19-2012 |
20120092567 | IMAGE DISPLAY DEVICE AND INFORMATION PROCESSING APPARATUS INCLUDING THE SAME - The object of the invention is to resolve the above problems in the conventional technique. A main object of the invention is to provide an image display device and a information processing apparatus which can prevent the problem such as slanting or missing of images displayed on a screen. | 04-19-2012 |
20120229781 | IMAGE DISPLAY APPARATUS AND MOBILE INFORMATION PROCESSING APPARATUS EQUIPPED WITH THE SAME - An image display apparatus includes an optical engine unit and a control unit, the optical engine unit being provided with a projection window guiding laser light to the exterior and the control unit rotatably supporting the optical engine unit. The optical engine unit is rotatable between a first position and a second position, the projection window being shielded within the casing of the mobile information processing apparatus in the first position and the projection window being exposed outside the casing of the mobile information processing apparatus in the second position. | 09-13-2012 |
20120307212 | IMAGE DISPLAY APPARATUS - The present invention provides an image display apparatus that inhibits deterioration of image quality caused by an increase in temperature of a laser light source apparatus. The image display apparatus of the present invention has a green color laser light source apparatus, a red color laser light source apparatus, a blue color laser light source apparatus, and a projection mouth in a first case. The first case has a fin on a side surface opposite to a projection mouth of the first case. The fin is provided in an air passage, the fin dissipating heat generated from laser light source apparatuses of each color and transferred via the first case. | 12-06-2012 |
20130088467 | IMAGE DISPLAY SYSTEM - The housing of the image display system is given with a rectangular box shape, and contains an optical system for projecting an image on a screen and a control circuit board for controlling the optical system and electrically connected to the first unit one above the other. Therefore, the image display system is compact enough and simply shaped enough for the user to carry it without any inconvenience. | 04-11-2013 |
