Abstract: A display device comprises a substrate; a circuit array layer comprising pixel drivers, data lines, first dummy lines, and second dummy lines; and a light emitting array layer. The display area comprises middle, first side, and second side regions. The data lines comprise first, second, and third data lines disposed in the middle, first side, and second side regions, respectively. The first dummy lines comprise a first data detour line disposed in the first side region and adjacent to a part of the second data line, and auxiliary lines. The second dummy lines comprise a second data detour line configured to connect the first data detour line to the third data line, and additional lines. The auxiliary lines comprise a bias auxiliary line to which a bias power is applied; and a second power auxiliary line to which a second power is applied.

Abstract: The present disclosure provides a composite substrate for an antenna module, which includes: a first non-magnetic substrate that is configured to have a first copper foil; a second non-magnetic substrate that is configured to have a second copper foil; and a magnetic sheet that is configured to be interposed between the first non-magnetic substrate and the second non-magnetic substrate and that is configured to be integrally laminated with the non-magnetic substrates, and further provides a preparation method thereof. The present disclosure provides a simplification of a process, low costs, a slim design, and a grip-feeling of a metal material while providing functions of wireless charging, MST, and NFC.

Abstract: The present invention relates to a process of preparing a continuous filament composed of a nano fiber, wherein nano fibers are prepared by spinning a polymer spinning dope in a spinning dope main tank (20) onto the surface of water or organic solvent (4a) of a collector (4), which contains water or inorganic solvent (4a) and has a conductive material (5) with a high voltage applied sunken in the water or organic solvent (4a), through nozzles (2) with a high voltage applied, and the nano fibers are pressed, drawn, dried and wound while being pulled by a rotary roller (6) rotating at a constant linear velocity from the location spaced more than 1 cm from one end of a dropping spot. The present invention can prepare a continuous filament composed of a nano fiber by an electrospinning method and a continuous process.
