Patent number: 7446830Abstract: Disclosed is a method for aligning polymer network liquid crystal. In the method, alignment of liquid crystal in a bulk state is controlled by means of an orientation power of polymer material itself which is formed by irradiating linearly polarized ultraviolet rays to monomer material having an orientation power, thereby achieving a transparent state at an initial state without an orientation layer. That is, Linearly polarized ultraviolet rays are irradiated to ultraviolet-hardening type monomers having an orientation power. Alignment of liquid crystal of a bulk state is controlled while the monomers are changed to polymers, thereby achieving an initial transparent state. The molecules of the liquid crystal are placed in disorder by a vertical electric field and the horizontal orientation power of a polymer chain.Type: GrantFiled: July 19, 2006Date of Patent: November 4, 2008Assignee: Boe Hydis Technology Co., Ltd.Inventors: Mi Sook Kim, Sung Hun Song, Seung Hee Lee

Patent number: 7315337Abstract: Disclosed is a liquid crystal display capable of improving the bending phenomenon of a liquid crystal panel. The liquid crystal display includes a liquid crystal panel having upper and lower substrates bonded each other with a liquid crystal layer interposed between them; an upper polarization plate attached to the upper surface of the upper substrate; and a lower polarization plate attached to the lower surface of the lower substrate. The upper and lower polarization plates have adhesion layers, respectively, which have different adhesion forces depending on the bending direction of the liquid crystal panel.Type: GrantFiled: June 14, 2005Date of Patent: January 1, 2008Assignee: Boe Hydis Technology Co., Ltd.Inventors: Sung Hun Song, Suk Man Yang

Patent number: 7169456Abstract: Disclosed is a transcription plate for forming orientation layer by coating printed orientation agent onto a substrate. The transcription plate comprises a base film and photosensitive resin plate, such as an APR layer, wherein a number of dots are arranged on the photosensitive resin plate in a regular fashion, and an arrangement of outer dots disposed outside of an active area of the transcription plate is denser than that of inner dots disposed within an active area of the transcription plate. The transcription plate enables the thickness of the orientation layer along the edge outside of the active layer of the transcription plate to be formed with the uniform thickness. Therefore, a uniform image property can be obtained by uniform rubbing. Further, because such phenomenon as conglomeration of the orientation agent does not occur, non-uniformity of cell gaps, which is caused by the superposition on the sealing line, can be solved.Type: GrantFiled: August 15, 2003Date of Patent: January 30, 2007Assignee: Boe-Hydis Technology Co., Ltd.Inventors: Hyang Yul Kim, Sung Hun Song

Publication number: 20030142248Abstract: Disclosed is a liquid crystal display device and method for manufacturing the same. The method comprises the steps of: preparing a transparent insulation substrate; forming a black matrix on the substrate and then forming a color filter layer on the black matrix; forming an indium tin oxide (ITO) or overcoating layer on the color layer; forming a pattern of post spacers on the ITO or overcoating layer; and forming a liquid crystal layer on the substrate by means of polymer dispersed liquid crystal. According to the present invention, the need for polyimide (PI) coating and rubbing processes can be obviated by using a post spacer color filter having a uniform cell gap and by using a polymer dispersed liquid crystal (PDLC), and the time for injecting liquid crystal can be decreased by using a one-drop filling (ODF) approach. Therefore, it has an improved screen grade, a decreased processing step and a cost-effective processing step.Type: ApplicationFiled: December 12, 2002Publication date: July 31, 2003Inventors: Tae Kyu Park, Sung Hun Song, Sung Woon Kim
