| 20110109866 | LIQUID CRYSTAL DISPLAY AND FABRICATION METHOD THEREOF - A liquid crystal display and a method of fabricating the same is capable of strengthening adhesion between a sealant and a lower plate in a panel with a high aperture ratio to which an organic protective film is applied. The organic protective film and a gate insulating film are patterned in such a manner that the sealant comes into contact with a substrate directly. Accordingly, the organic protective film or the gate insulating film at the area coated with the sealant is partially or entirely removed to directly contact the sealant with the gate insulating film or the lower glass, thereby strengthening the adhesion between the sealant and the lower plate. | 05-12-2011 |

| 20100322456 | Speaker device for mobile terminal - A speaker device for a mobile terminal enlarges resonance space of a speaker while decreasing a size of the mobile terminal. The speaker device for a mobile terminal includes at least one speaker installed within a main body of the mobile terminal and a speaker bracket installed at one surface of an electronic circuit board mounted within the main body. In addition, the speaker bracket fixes the at least one speaker in place and has housing space to enclose the at least one speaker therein. At least one resonance groove is formed in a portion enclosed by the speaker bracket in one surface of the electronic circuit board. Because resonance space can be enlarged without increasing a size of the speaker bracket, an entire thickness of the mobile terminal can be reduced and thus a size and thickness of the mobile terminal can be decreased. | 12-23-2010 |
| 20110219159 | USB DONGLE DEVICE AND OPERATION METHOD THEREOF, DONGLE EXPANDED DEVICE CONNECTED TO USB DONGLE DEVICE - A universal serial bus (USB) dongle device and method support a connection to a dongle expanded device to perform high speed and multiple communications while observing a USB standard form. The USB dongle device includes a body and a plug formed in an edge of one side of the body. The plug includes a basic connection unit corresponding to a USB basic connection port and an expansion connection unit surrounding the basic connection unit, in which at least one signal line is formed. | 09-08-2011 |
