Patent number: 8427529Abstract: A three-dimensional display for the viewer to watch through glasses is provided, wherein the glasses have two lenses and the polarized directions thereof are perpendicular to each other. The three-dimensional display includes a display panel and a liquid crystal phase modulator. The display panel, suitable for displaying an image, has a plurality of pixels arranged in array and a polarizer having a transmission axis, wherein the polarizer disposed between the pixels and the glasses. The liquid crystal phase modulator suitable for providing phase retardation includes a liquid crystal layer and an alignment layer adjacent to the display panel. An included angle between an alignment direction of the alignment layer and the transmission axis is substantially equal to n×45 degrees, wherein an absolute value of n is an integer. The liquid crystal phase modulator adjusts a phase of the image and then outputs an image with three-dimensional information.Type: GrantFiled: November 17, 2008Date of Patent: April 23, 2013Assignee: Au Optronics CorporationInventors: Chao-Yuan Chen, Chih-Wen Chen, Geng-Yu Liu, Wan-Hua Lu, Ting-Jui Chang

Patent number: 8363194Abstract: In a liquid crystal display panel, a pixel electrode includes at least a main electrode strip and a plurality of sub electrode branches. The sub electrode branches extend outwardly from two opposite edges of the main electrode strip. The main electrode strip includes at least a node-controlling portion, the controlling width of the node-controlling portion are different from a trunk width of the main electrode strip. Otherwise, a plurality of first sub electrode branches and a plurality of second sub electrode branches are extend outwardly from two opposite edges of the main electrode strip respectively. Relating to the position of the first sub electrode branches, the second sub electrode branches has a position-shift amount along the extending direction of the main electrode strip. The position-shift amount is smaller than the branch width of the first or second sub electrode branch.Type: GrantFiled: April 30, 2012Date of Patent: January 29, 2013Assignee: AU Optronics Corp.Inventors: Wan-Hua Lu, Chia-Yu Lee, Pei-Chun Liao, Ting-Jui Chang
