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:
A discrete-time receiver includes: a sampling mixer sampling an input signal according to a sampling clock; a discrete-time filter adjusting a decimation rate by using a control signal and filtering the sampled signal by using a filter clock; and a clock generator generating a sampling clock to be supplied to the sampling mixer, and generating the control signal and the filter clock by comparing the frequency of the sampling clock with a pre-set output frequency. Over a broadband input signal, a dynamic range of an output signal can be improved.

Abstract:
A rotatable fish hook is configured for attachment to a legacy fishing lure. The rotatable fish hook may comprise: a barb; an attachment piece for connecting the hook to a fishing lure; and a rotation mechanism, configured to rotationally isolate the barb from the connecting piece. The barb is free to rotate while the attachment piece remains stationary. The rotatable fish hook may comprise: a shank and a bend connected to the shank at a first end and the shank connected to the barb at a second end. The rotation mechanism is configured to rotationally isolate the shank, the bend and the barb from the attachment piece. The shank, the bend and the barb are free to rotate while the attachment piece remains stationary.
Abstract:
A display device includes a backlight assembly, a display panel, a top chassis and a sealing member. The backlight assembly includes a light-generating unit, a receiving container receiving the light-generating unit and a mold frame disposed along an edge portion of the receiving container. The display panel is disposed on the mold frame. The top chassis is coupled to the receiving container, covers an edge portion of the display panel and fixes the display panel by. The sealing member is disposed between the mold frame and the top chassis to surround an end portion of the display panel, such as to fully seal a space between the end portion of the display panel and the mold frame. The sealing member has elasticity, insulating properties and adsorption capacity for foreign matter.
Abstract:
A backlight assembly includes a light source, a light guide plate, and a receiving container having a combination guide part. The coupling guide part is inwardly protruded with respect to the sidewalls of the receiving container. The coupling guide part corresponds with a guide recess on the light guide plate to guide the light guide plate to a proper position. The coupling guide part may also include a screw thread to couple the receiving container with an external case. Therefore, the receiving container may be easily coupled with the external case and the light guide plate may be guided to a proper position via the combination guide part to thereby simplify a manufacturing process of the backlight assembly and reduce its size.
Abstract:
A liquid crystal display includes a liquid crystal panel displaying images, a light source supplying light to the liquid crystal panel, a circuit board including at least one of a brightness sensor and a temperature sensor, a frame including a plurality of sidewalls each including an inner surface, an outer surface and a top surface, the frame including a recess into which the circuit board is inserted downwardly, and the top surface including an open area through which the recess is accessible, and a blocking member covering the open area of the top surface where the frame recess is opened.
Abstract:
A backlight assembly comprises a light source unit emitting light, a heat-blocking plate disposed over the light source unit to prevent heat generated from the light source unit from being upwardly transmitted, and a receiving container receiving the light source unit and the heat-blocking plate. The receiving container includes a bottom plate and a plurality of sidewalls. Each of the sidewalls extends from a side of the bottom plate and has openings formed through each of the sidewalls. The openings are formed over the heat-blocking plate.
