Patent number: 7256848Abstract: In a method and apparatus of aligning liquid crystal, a first ion beam is formed. The first ion beam is transformed into a second ion beam having transformed cross-section. The second ion beam advances toward a thin film including carbon-carbon double bond. The second ion beam forms a first angle with respect to the thin film. The second ion beam is transformed into an atomic beam. The atomic beam is irradiated onto the thin film to break the carbon-carbon double bond. The carbon-carbon double bond is broken to form a polarized functional group for aligning a liquid crystal molecule.Type: GrantFiled: October 14, 2003Date of Patent: August 14, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Dae-Ho Choo, Hwan-Kyeong Jeong, Bong-Woo Lee

Publication number: 20040201806Abstract: According to the method of forming a multi-domain for aligning liquid crystal, an alignment film is formed on a substrate. The alignment film is scanned with an atomic beam irradiated in a first direction to form a first domain in a first region of the first alignment film. Then, the alignment film is scanned with the atomic beam irradiated in a second direction to form a second domain in a second region of the first alignment film. Thus, the multi-domain is formed by non-contacting method, so that a number of process and a time used for manufacturing the multi-domain are reduced.Type: ApplicationFiled: October 7, 2003Publication date: October 14, 2004Applicant: Samsung Electronics Co., Ltd.Inventors: Dae-Ho Choo, Hak-Jin Kim, Hong-Gyun Kim, Hwan-Kyeong Jeong, Bong-Woo Lee
