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:
An electroless surface treatment plated layer of a printed circuit board, a method for preparing the same, and printed circuit board including the same. The electroless surface treatment plated layer includes: electroless nickel (Ni) plated coating/palladium (Pd) plated coating/gold (Au) plated coating, wherein the electroless nickel, palladium, and gold plated coatings have thicknesses of 0.02 to 1 μm, 0.01 to 0.3 μm, and 0.01 to 0.5 μm, respectively. In the electroless surface treatment plated layer of the printed circuit board, a thickness of the nickel plated coating is specially minimized to 0.02 to 1 μm, thereby making it possible to form an optimized electroless Ni/Pd/Au surface treatment plated layer.

Abstract:
A method and apparatus for transmitting and receiving video data via a digital data interface are provided. The video data transmission method includes: inserting three-dimensional (3D) video data into a video data period in a video frame; inserting information regarding a 3D image format of the 3D video data into a data island period in the video frame; and transmitting the video frame via the digital data interface.
Abstract:
In the data transmission method, a MAC layer receives data from an upper layer, classifies the data according to destination addresses and traffic identifiers, aggregates the data by destination address and traffic identifier as a first transmission unit, aggregates the first transmission units having the identical destination address as a second transmission unit, and transmits the second transmission units having different destination addresses in a single frame. The data transmission method allows packets transferred from the upper layer to be hierarchically aggregated by DAs and TIDs and then packaged into a data unit for each destination such that it is possible to transmit the data at an optimal data rate for each destination terminal.
