Abstract: The viewing angle of a Liquid Crystal Display (LCD) apparatus is expanded by means of a sampled light redirecting layer, In one embodiment, the sampled light redirecting layer is formed as a compensation layer disposed between a top polarizing plate and the rest of a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal layer interposed therebetween. The compensation layer includes at least two optical path changing patterns disposed in interleaved manner. The two optical path changing patterns have different refractive indexes. As a result of the different refractive indices and shapes of the at least two different optical path changing patterns some of the light rays sampled out of the output of the rest of a liquid crystal display panel are directed in a first direction by means of reflection or refraction and some are directed in a different second direction, thereby improving a side visibility of the display apparatus.

Abstract: Disclosed is a microfluidic chip capable of accurately and quickly detecting presence of a trace amount of a target within a fluid sample. It has a channel structure comprising a sample inlet for feeding a sample therethrough, a first reservoir for primarily storing the sample therein, a second reservoir for secondarily storing the sample therein, a first reaction portion in which a target is conjugated with a label, a second reaction portion in which the labeled target undergoes a specific reaction, such as an antigen-antibody reaction, and a delaying portion, located between the first and the second reaction portion, for decreasing a flow rate of the sample.

Abstract: Disclosed is a module for rapidly detecting analytes in fluids with high effectiveness and a chip having the module. The module includes a microchannel, which has a filtering zone for removing noise materials and a reaction zone wherein labeling reaction and immobilization reaction for detection of analytes are performed, sample fluid moving through the microchannel due to capillary floating. In a case where the chip having the module is used in detecting analytes in fluids, it is possible to minimize dead volume of sample fluid so that high effective volume ratio can be implemented. Therefore, the chip can be used in detecting analytes from the minimum amount of sample fluid.

Abstract: Disclosed is a method of bonding upper and lower substrates for manufacturing a plastic micro chip comprising the upper substrate, the lower substrate and a sample filling space having a predetermined height for filling a sample between the upper and lower substrates. According to the method, the upper and lower substrates are bonded by introducing an organic solvent between the upper and lower substrates. In addition, the invention provides a method of manufacturing a micro chip using the method and a micro chip manufactured according to the method. According to the invention, it is possible to easily and precisely bond the upper and lower substrates of the plastic micro chip.

Abstract: Disclosed is a fluid analysis chip including a microchannel formed within the chip. The chip includes a sample and a sample outlet communicating with an outside of the chip, and has a structure where the sample inlet and the sample outlet communicate with each other through the closed channel. An expanding part formed in a longitudinal direction of a channel in such a manner that a pair of inner walls corresponding to each other has a larger sectional area at a part or a whole thereof is formed. Therefore, fluids, which pass through the channel adjacent to the expanding part, move while making contact with only another pair of inner walls of the channel, which correspond to each other.

Abstract: Disclosed is a focusing channel device which focuses fluid containing micro particles so that the micro particles flow in a line. The channel device comprises a nozzle formed by left and right walls each of which comprises an inclination surface. The cross sectional area in vertical direction decreases from the entrance of the nozzle toward the exit of the nozzle. The shape of cross sectional view in horizontal direction is asymmetric for the central line in the length direction. Using the focus channel device of the invention, the micro particles in the fluid are not combined with each other and passed through the channel one by one. Thus, blockage of the channel or combination and movement of two particles together does not occur.

Abstract: Disclosed is a channel filter for separating microparticles, and more particularly to a channel filter which can easily separate a sample having various sized microparticles by using a surface topology. In the disclosed channel filter, a topology having an upward/downward reference height from a sample inlet to an outlet is continuously or discontinuously formed, and thus it is possible to efficiently separate microparticles from a sample liquid.
