20080198298 | Backlight unit and display device having the same - Provided are a backlight unit and a display device having the same. The backlight unit includes a case having an opening, at least one lamp assembly disposed on a side surface of the case and including a light source, an optical transreflective unit on the case, the optical transreflective unit transmitting a portion of first light passing through the opening and reflecting a portion of second light generated from the light source, and an optical sheet including a first diffusion unit on the optical transreflective unit. | 08-21-2008 |
20090303420 | Liquid crystal display device and method of driving the same - A liquid crystal display device includes: first and second substrates facing and spaced apart from each other, each of the first and second substrates having an image-displaying sub pixel and a viewing angle-adjusting sub pixel; a thin film transistor corresponding to each of the image-displaying sub pixel and the viewing angle-adjusting sub pixel; a liquid crystal display layer between the first and second substrates, the liquid crystal layer having a negative dielectric constant anisotropy; a first field distortion means in the image-displaying sub pixel; and a second field distortion means in the viewing angle-adjusting sub pixel. | 12-10-2009 |
20110175819 | ALPHABETIC CHARACTER INPUT APPARATUS AND METHOD THEREOF - There is provided an alphabetic character input apparatus including a data storage unit configured to store therein alphabetic character assignment information of each of keys in an alphabetic character input section and a program for inputting an alphabetic character; a key input unit configured to detect a key manipulation signal of a user to select an alphabetic character assigned to each of the keys; and a memory configured to store therein alphabetic character assignment information of a key corresponding to a key manipulation signal lately input by the user such that the alphabetic character assignment information of the key is assigned to a clone key. | 07-21-2011 |
20110316827 | METHOD OF FABRICATING A LIQUID CRYSTAL DISPLAY DEVICE HAVING IMAGE-DISPLAYING AND VIEWING ANGLE-ADJUSTING SUB PIXELS AND METHOD OF DRIVING THE SAME - A liquid crystal display device includes: first and second substrates facing and spaced apart from each other, each of the first and second substrates having an image-displaying sub pixel and a viewing angle-adjusting sub pixel; a thin film transistor corresponding to each of the image-displaying sub pixel and the viewing angle-adjusting sub pixel; a liquid crystal display layer between the first and second substrates, the liquid crystal layer having a negative dielectric constant anisotropy; a first field distortion means in the image-displaying sub pixel; and a second field distortion means in the viewing angle-adjusting sub pixel. | 12-29-2011 |
20120094569 | LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - Provided are an LCD device that can control a viewing angle freely and a manufacturing method thereof. The LCD device includes a first substrate, a second substrate, and an LC layer interposed between the first and second substrates. The LCD device further includes red, green, blue, and viewing angle controlling subpixels. These subpixels are driven in a VA mode. The red, green, and blue subpixels have a transflective structure. The viewing angle controlling subpixel has a transmissive or transflective structure. | 04-19-2012 |
20130044464 | BACKLIGHT UNIT AND DISPLAY DEVICE HAVING THE SAME - Provided are a backlight unit and a display device having the same. The backlight unit includes a case having an opening, at least one lamp assembly disposed on a side surface of the case and including a light source, an optical transreflective unit on the case, the optical transreflective unit transmitting a portion of first light passing through the opening and reflecting a portion of second light generated from the light source, and an optical sheet including a first diffusion unit on the optical transreflective unit. | 02-21-2013 |
20130145647 | METHOD FOR DEHYDRATING EVAPORATOR OF AIR CONDITIONER OF VEHICLE - A method for dehydrating an evaporator of an air conditioner of a vehicle is provided to drive a blower motor depending on the humidity of the evaporator while monitoring a dry state of the evaporator, thus allowing the evaporator to be appropriately dried and preventing a problem from being caused by the discharge of a battery, therefore minimizing an odor generated by the air conditioner of the vehicle owing to effective drying of the evaporator of the air conditioner, and consequently considerably improving the marketability of the vehicle. | 06-13-2013 |
20130149951 | AIR DISCHARGE SYSTEM OF HVAC SYSTEM FOR VEHICLE - An air discharge system of an HVAC (Heat, Ventilation, and Air Conditioning) system for a vehicle, may include a first path provided in the HVAC system to communicate with discharge ports of a front seat, the first path allowing air that has passed through a heat exchanger to be discharged through the discharge ports of the front seat, a second path diverged from the first path to communicate with discharge ports of a rear seat, the second path allowing air that has passed through the heat exchanger to be discharged through the discharge ports of the rear seat, thus enabling the independent discharge of air to the rear seat, and a first control door provided at a position where the first path and the second path diverge from each other, thus opening or closing the second path. | 06-13-2013 |
