Publication number: 20070279562Abstract: An alignment layer for an LCD includes a thin layer of silicon oxide SiOx. The silicon oxide layer horizontally aligns liquid crystals thereon when the value of x is in the range from about 1.0 to about 1.5, but vertically aligns the liquid crystals when the value of x is in a range from about 1.5 to about 2.0. The alignment layer is readily formed on a large area of the substrate through chemical vapor deposition or evaporation deposition. Because the alignment layer is thermally and physically stable, the operational characteristics of the liquid crystal display employing this alignment layer are improved. In addition, the alignment layer has a thickness of about 500 to about 3000 angstroms thereby improving light transmittance of the LCD having the alignment layer.Type: ApplicationFiled: April 12, 2007Publication date: December 6, 2007Inventors: Soon-Joon Rho, Baek-Kyun Jeon, Kyoong-Ok Park, Hee-Keun Lee, Hong-Koo Baik, Kyung-Chan Kim, Jong-Bok Kim, Byoung-Har Hwang, Dong-Choon Hyun, Han-Jin Ahn

Patent number: 6433857Abstract: Disclosed herewith is an optical triangulation displacement sensor using a diffraction grating. The optical triangulation displacement sensor includes a light source element, a condenser, a light-receiving element, an image formation lens, a transmission grating and a light-receiving element. The light source element generates light of certain intensity. The condenser receives the light from the light source element and transmits the light to the surface of measurement. The image formation lens receives the light reflected by the surface of measurement. The transmission grating converts the reflected light having passed through the image formation lens into a plurality of diffracted light rays. In the light-receiving element, an image is formed by the diffracted light rays incident from the transmission grating.Type: GrantFiled: April 19, 2001Date of Patent: August 13, 2002Assignee: Korea Advanced Institute of Science and TechnologyInventors: Soo Hyun Kim, Kyung Chan Kim, Se Baek Oh
