Patent application number | Description | Published |
20080297730 | Projector - A projector includes: a plurality of light sources for generating lights having different colors; a spatial optical modulator for performing a line-modulation of the lights; wavelength selection filters, disposed between the light sources and the spatial optical modulator, for transmitting or reflecting the lights according to light wavelengths; and a scanner for projecting the light incident from the spatial optical modulator in a line-scan scheme. | 12-04-2008 |
20080304526 | GREEN LASER OPTICAL PACKAGE - A green laser optical package includes a laser light source generating light of an infrared wavelength band, a harmonic wave generator converting an infrared light output from the laser light source into a second harmonic wave so as to output the converted second harmonic wave, and at least one support member attached to side surfaces of the laser light source and the harmonic wave generator. | 12-11-2008 |
20080309887 | Micro-scanner and image projection apparatus using the same - A micro-scanner adapted for being miniaturized and an image projection apparatus using the same. The micro-scanner includes a scan mirror for scanning incident light to a screen while swinging about a rotary shaft; and upper and lower supports for rotatably supporting the top and bottom parts of the rotary shaft. The upper and lower supports having a driving unit for supplying driving force for rotating the scan mirror. | 12-18-2008 |
20090185354 | HEAT RADIATING STRUCTURE FOR ELECTRONIC MODULE AND ELECTRONIC DEVICE HAVING THE SAME - A heat radiating structure for an electronic module and an electronic device having the same structure thereon. The heat radiating structure is formed at the bottom of the electronic module to release the generated heat from the electronic module, and includes an impact absorber, which absorbs impact transferred from the outside. A heat radiating sheet is formed with a plurality of the multi-layered heat conductive sheets and is in contact with the bottom of the electronic module by covering the outside of the impact absorber. | 07-23-2009 |
20110069405 | FOCUSING DEVICE FOR BEAM PROJECTOR - A focusing device for a beam projector which includes a casing; a lens holder having at least one lens which is movable forward or backward in the direction of the optical axis; a movable member located at a side of the lens holder to be movable parallel to the direction of the optical axis together with the lens holder; and a control knob located adjacent to the lens holder and rotatably coupled on the casing. | 03-24-2011 |
20110102599 | MOBILE TERMINAL INCLUDING PROJECTOR AND CONTROL METHOD THEREOF - Disclosed is a mobile terminal for providing a blackboard function to an image projected through a projector, which includes a projector for projecting an image on a screen, a camera for photographing the image projected through the projector and transferring the photographed image to an image processor. The image processor processes the image transferred from the camera and transfers the processed image to a controller. The controller controls the operation of the mobile terminal including recognizing an effective region for the projected image where infrared rays are detected from the photographed image so as to recognize an indication position of an indication device. The indication device generates infrared rays, in the projected image, and when the infrared rays are detected, a preset mark is displayed on a position of the detected infrared rays by using the projector. | 05-05-2011 |
20150080658 | ENDOSCOPE DEVICE - Provided is an endoscope device and a method of operating the endoscope device. The endoscope device includes: a knob driving part configured to be driven in a mode selected by an operator from either of an automatic mode and a manual mode; a bending part connected to the knob driving part and configured to change a position of a distal end of the endoscope device by driving of the knob driving part, a power generating part configured to provide power to the knob driving part; and a power transmitting part configured to drive the power generating part according to a manipulation of the knob driving part. | 03-19-2015 |
