The PCB comprises a plurality of coil conductor patterns made of conductive material and shaped into strips, which is provided on the plurality of conductor layers, respectively, such that the plurality of coil conductor patterns are parallel to each other and positioned on the same plane perpendicular to the conductor layers, and in which each of the plurality of coil conductor patterns is longer than an adjacent inner coil conductor pattern.
Abstract:
Disclosed is a liquid crystal display apparatus in which a liquid crystal display module and cases are tightly combined. At least one protuberance formed on a top chassis of the liquid crystal display module combines at least one fixing portion formed on a portion of a rear case corresponding to the at least one protuberance. Also, a fixing protuberance formed on a portion of a front case is inserted into between the liquid crystal display module and the rear case, thereby preventing the liquid crystal display module from being moved. Therefore, the liquid crystal display module and the cases are tightly combined, and productivity of the liquid crystal display apparatus can increase by reducing the number of parts demanded for fabrication of the liquid crystal display module and the cases.
Abstract:
A liquid crystal display device in which an integrated printed circuit board is manufactured by integrating a circuit of a gate portion with a source portion and is located on the source side of the liquid crystal panel, and a flexible circuit board according to the COF method is provided on the gate side, and the flexible circuit board is supported towards a mold frame to reduce the area and the volume which is occupied by a portion except for a screen is disclosed. The liquid crystal display device comprises a liquid crystal display panel, an integrated printed circuit board, a flexible circuit board for transferring a gate driving signal and a data driving signal to the liquid crystal display panel, and a mold frame for receiving the liquid crystal display panel and a back light assembly. A support member for supporting the flexible circuit board towards the mold frame is provided on one side of a chassis. Since the gate side flexible circuit board is easily supported by the support member towards the mold frame, the planar area increasing of the liquid crystal display device is prevented.

The first lamp unit has a first light generating portion and a second light generating portion integrally connected with the first light generating portion. The light guide unit has side surfaces for receiving light from the first lamp unit, a reflecting surface for reflecting the light input through the side surfaces, and an emitting surface for emitting the light input through the side surfaces and reflected from the reflecting surface. The receiving container has a bottom and sidewalls each extended from the bottom and facing corresponding one of the side surfaces of the light guide unit, for receiving the first lamp unit and light guide unit. Further the receiving container is configured to have a plurality of parts separate from each other to withdraw the first lamp unit from the receiving container.
Abstract:
A method for fabricating a large-area nanoscale pattern includes: forming multilayer main thin films isolated by passivation layers; patterning a first main thin film to form a first main pattern; forming a first spacer pattern with respect to the first main pattern; and forming a second main pattern by transferring the first spacer pattern onto a second main thin film. By using multilayer main thin films isolated by different passivation films, spacer lithography capable of reducing a pattern pitch can be repetitively performed, and the pattern pitch is repetitively reduced without shape distortion after formation of micrometer-scale patterns, thereby forming nanometer-scale fine patterns uniformly over a wide area.
