Publication number: 20140063584Abstract: An electrochromic thin film, an electrochromic device, and a manufacturing method thereof are disclosed. The electrochromic device comprises: a first substrate and a second substrate provided opposite to each other, a first transparent electrically-conductive layer provided on the inner side of the first substrate, a second transparent electrically-conductive layer provided on the inner side of the second substrate, an organic-inorganic electrochromic thin film provided between the first transparent electrically-conductive layer and the second transparent electrically-conductive layer. The organic-inorganic electrochromic thin film is obtained by forming a mesh-like microsphere-film on the first transparent electrically-conductive layer; forming an inorganic electrochromic film in the voids of the microsphere-film and removing the microsphere-film; and making the inorganic electrochromic film and an organic electrochromic solution undergo a polymerization reaction.Type: ApplicationFiled: August 28, 2013Publication date: March 6, 2014Applicant: BOE TECHNOLOGY GROUP CO., LTD.Inventor: Yue SHI

Patent number: 8665512Abstract: Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.Type: GrantFiled: September 14, 2012Date of Patent: March 4, 2014Assignee: View, Inc.Inventors: Robin Friedman, Sridhar Kailasam, Rao Mulpuri, Ron Powell, Dhairya Shrivastava
