Publication number: 20130194533Abstract: A display device employing a liquid crystal module and a method for fabricating the display device are provided. The liquid crystal module includes a first substrate and a second substrate, wherein the first substrate is disposed opposite to the second substrate; a first photo-alignment layer disposed on a top surface of the first substrate, and a second photo-alignment layer disposed on a bottom surface of the second substrate, wherein the first and second photo-alignment layers include a plurality of protrusions, and wherein the protrusions are formed by polymerizing non-polar monomers having two or three acrylate functional groups; and a liquid crystal layer disposed between the first and second photo-alignment layers.Type: ApplicationFiled: January 30, 2013Publication date: August 1, 2013Applicant: INNOLUX CORPORATIONInventors: Rong-Ching YANG, Wei-Chuan HUANG, Han-Chang CHEN, Shih-Fang LIAO, Hung-Ming SHEN, Wan-Ling HUANG, Kai-Neng YANG, Tsau-Hua HSIEH

Patent number: 8094284Abstract: A method of manufacturing a liquid crystal display panel is provided. A photo-alignment layer and a patterned pixel electrode are formed on a first and a second substrates respectively. A liquid crystal layer is formed between the photo-alignment layer and the patterned pixel electrode. The patterned pixel electrode includes intersected electrodes having a first directional portion and a second directional portion intersected therewith, and stripe electrodes having slits therebetween connect at least one of the first directional portion and the second directional portion. When an electric field between the first and the second substrates is substantially zero, the liquid crystal molecules near the photo-alignment layer have a pre-tilt angle while those on another side are substantially perpendicular to the second substrate. As the liquid crystal layer is driven, the liquid crystal molecules of the liquid crystal layer are substantially arranged along an extending direction of the slits.Type: GrantFiled: April 21, 2008Date of Patent: January 10, 2012Assignee: Au Optronics CorporationInventors: Rong-Ching Yang, Ming-Hung Wu, Chia-Ming Chen, Yu-Ping Kuo

Patent number: 7749783Abstract: A method of forming a display panel includes providing a first substrate having a transparent electrode, and a second substrate having a pixel electrode. Subsequently, an alignment material is provided and covers on the transparent electrode and/or the pixel electrode, and a photoelectric twisting layer is provided between the first substrate and the second substrate. The alignment material is first in a non-aligned state, and is radiation-polymerizable. The photoelectric twisting layer does not include any radiation-polymerizable material. Thereafter, a voltage difference is applied to drive molecules of the photoelectric twisting layer, and a radiating process is performed on the alignment material. The twisted molecules of the photoelectric twisting layer induce the surface molecules of the alignment material to arrange in an ordered state, and the alignment material is polymerized according to the ordered state as a first alignment film.Type: GrantFiled: April 2, 2009Date of Patent: July 6, 2010Assignee: AU Optronics Corp.Inventors: Rong-Ching Yang, Ming-Hung Wu, Shih-Feng Hsu, Li-Ya Yeh, Kuo-Hwa Wu, Wei-Yi Chien

Patent number: 7684001Abstract: A method for manufacturing a liquid crystal display panel is provided. A photo-alignment layer is formed on a first substrate. Patterned pixel electrodes including intersected electrodes and stripe electrodes are formed on a second substrate. A liquid crystal layer is formed between the photo-alignment layer and the patterned pixel electrodes. Each intersected electrode has a first directional portion and a second directional portion interlacing thereto. The stripe electrodes with silts connect the first and/or the second directional portions. When an electric field between the first and the second substrates is substantially zero, liquid crystal molecules near the photo-alignment layer are arranged at a pre-tilt angle, while those disposed at another side near the second substrate are substantially perpendicular to the second substrate. As the liquid crystal layer is driven, the liquid crystal molecules of the liquid crystal layer are substantially arranged along an extending direction of the slits.Type: GrantFiled: August 23, 2007Date of Patent: March 23, 2010Assignee: Au Optronics CorporationInventors: Rong-Ching Yang, Ming-Hung Wu, Chia-Ming Chen, Yu-Ping Kuo
