20100079697 | BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY HAVING THE SAME - A backlight unit including: a light emitting diode (LED) module including a metal substrate and an LED which is disposed on a first side of the metal substrate; a frame on which the LED module is mounted; a first mounting portion formed lengthwise on the LED module; and a second mounting portion formed on the frame, the second mounting portion remaining within a width of the LED module. | 04-01-2010 |
20110292524 | FOCUS ADJUSTMENT DEVICE FOR USE IN PORTABLE IMAGE PROJECTION APPARATUS - A focus adjustment device for adjusting a focus state of a projection lens unit in an image projection apparatus is provided. The focus adjustment device includes a focus adjustment member rectilinearly movable in a first direction; a rotational shaft; a first movement-converting member for converting a rectilinear movement of the focus adjustment member into a rotary movement of the rotational shaft; and a second movement-converting member for converting the rotary movement of the rotational shaft into in a rectilinear movement of the projection lens unit along a focusing direction. | 12-01-2011 |
20130044298 | FOCUS REGULATING APPARATUS OF PROJECTOR AND PROJECTOR USING THE SAME - Disclosed are a focus regulating apparatus for use with a projector and a projector using the same. The apparatus has a structure which is designed to overcome asymmetry in focus regulation due to the optical characteristics of the projector. The focus regulating apparatus of a projector includes: a focus regulator, which is provided in a projection lens unit of a projector main body so that the focus can be regulated by rotating a lens barrel of the projection lens unit; and an actuator, which gears with the focus regulator and moves rectilinearly with respect to the projector main body, thereby causing the focus regulator to rotate. The rotation of the focus regulator is varied when the actuator rectilinearly moves at a constant speed. The apparatus thus enables an asymmetry in focus regulation to be overcome when a screen size for the projector is adjusted. | 02-21-2013 |
20130077054 | PROJECTOR AND DISPLAY APPARATUS HAVING THE SAME - The projector according to an exemplary embodiment includes an optical system which forms, expands, and projects the image, and includes at least one light source; a light source dissipation unit for dissipating heat generated by the light source; a plurality of circuit boards for operating the projector; an intake unit having an intake opening where external air is received; an exhaust unit having an exhaust opening where the received air is expelled; and a flow path dividing unit which divides a cooling flow path formed between the intake opening and the exhaust opening into an upper cooling flow path and a lower cooling flow path, wherein the light source dissipation unit is placed on the upper cooling flow path and at least one of the plurality of circuit boards is placed on the lower cooling flow path. | 03-28-2013 |
20140043678 | PROJECTION APPARATUS INCLUDING INTEGRATED IMAGE PROJECTIONUNIT AND SCREEN UNIT - A projection apparatus, in which an image projection unit and a screen unit are integrally mounted on one mounting unit, is provided. The screen unit includes a screen configured to display an image, and a screen attaching part to which the screen is attached. The screen attaching part includes a front plate to which the screen is attached, a rear plate, and a strength reinforcing member interposed between the front plate and the rear plate. | 02-13-2014 |
20140132846 | SCREEN DEVICE AND PROJECTION APPARATUS HAVING A SCREEN DEVICE - A screen device and a projection apparatus having the same are provided. The screen device includes a screen on which an image is projected, and a support panel which includes a pair of plates and a strength reinforcement member arranged between the pair of plates, wherein the screen is attached to any one of the pair of plates. | 05-15-2014 |
20140132935 | PROJECTION APPARATUS - A projection apparatus includes an image projection unit configured to form an image and project the formed image, a screen unit configured to display the image projected from the image projection unit, and a mounting unit on which the image projection unit and the screen unit are integrally mounted. The screen unit is formed to have a curvature. | 05-15-2014 |
20150026491 | REMOTELY CONTROLLABLE ELECTRONIC DEVICE AND SYSTEM INCLUDING THE SAME - An electronic device is provided. The electronic device includes a controller configured to transition the electronic device into a sleep mode, and a communication interface configured to establish a network session with the external computing device when the electronic device into the sleep mode, wherein the communication interface is configured to maintain the network session with the external computing device when the electronic device is in the sleep mode, and to transition the electronic device into a non-sleep mode in response to a signal, for requesting that the electronic device gets out the sleep mode, being received through the maintained network session. | 01-22-2015 |
