Abstract:
Provided is a method of manufacturing a wire grid polarizer in which a stable color coordinate can be implemented. According to the present invention, in a process where a second grid pattern of metal pattern is formed over a first grid pattern made of resin material, metal layer is deposited in a concave portion formed between adjacent first grid patterns to form void portion and a width and a height of the second grid pattern are adjusted depending on adjustment of a width of the voids, and thereby improving a process efficiency.
Abstract:
The present invention relates to a wire grid polarizer capable of securing a high brightness and reducing the number of processes, a liquid crystal device including the wire grid polarizer, and a method of manufacturing the wire grid polarizer. According to the present invention, the wire grid polarizer, including first grids arranged in parallel at certain intervals over a substrate and second grids formed on the first grids, can be formed using only an imprint process, a deposition process, and a wet etch process. Accordingly, the number of processes and the process costs and time can be reduced, and high reliability can be guaranteed.

Abstract:
The present invention relates to an X-ray imaging apparatus, comprising: an X-ray imager including an X-ray beam generator for emitting an X-ray beam, an X-ray beam detector for detecting the X-ray beam to obtain an X-ray image of an object, and a main body unit in which the X-ray beam generator and the X-ray beam detector are installed; and a three-dimensional scanner arranged in the X-ray imager in order to obtain an image of the outer appearance of the object. According to the present invention, an X-ray image and an image of the outer appearance of an object, for example, an image of the skull and an image of the face, can be obtained at the same time, thereby minimizing image correction procedures for matching two images.

The disclosed lighting apparatus may be a lighting apparatus for measuring the position of a mobile terminal by way of visible light communication. The lighting apparatus comprises one or more boundary lighting devices positioned in a boundary part of the lighting apparatus, which are configured to emit visible light that includes information for identifying a position of the mobile terminal (identification information); one or more inner lighting devices positioned in an inner part of the lighting apparatus, which are configured to emit visible light that includes the identification information; and one or more boundary concentrator units, which are implemented respectively on at least some of the one or more boundary lighting devices, and which are configured to concentrate the visible light emitted from the at least some boundary lighting devices.
Abstract:
Provided is a method for manufacturing a printed circuit board. The method for manufacturing a printed circuit board includes preparing an insulation board, irradiating a laser onto a graytone mask to each a surface of the insulation board, thereby forming a circuit pattern groove and a via hole at the same time, and filling the circuit pattern groove and the via hole to form a buried circuit pattern and the via. Thus, the circuit pattern groove and the via hole may be formed using the graytone mask at the same time without performing a separate process for forming the via hole. Therefore, the manufacturing process may be simplified to reduce the manufacturing costs.
Abstract:
Disclosed herein is a method of manufacturing a printed circuit board, including: mounting a strip substrate on a fixing member; separating the strip substrate into unit substrates by performing a singulation process; attaching solder balls onto the unit substrates using a jig; and fixing the solder balls on the unit substrates by performing a reflow process. The method of manufacturing a printed circuit board is advantageous in that the solder balls can be accurately formed at the predetermined positions of the strip substrate because they are attached to the unit substrates after the warpage of the strip substrate was reduced by a singulation process.
