Patent number: 11561446Abstract: Electrochromic devices and methods may employ the addition of a defect-mitigating insulating layer which prevents electronically conducting layers and/or electrochromically active layers from contacting layers of the opposite polarity and creating a short circuit in regions where defects form. In some embodiments, an encapsulating layer is provided to encapsulate particles and prevent them from ejecting from the device stack and risking a short circuit when subsequent layers are deposited. The insulating layer may have an electronic resistivity of between about 1 and 108 Ohm-cm. In some embodiments, the insulating layer contains one or more of the following metal oxides: aluminum oxide, zinc oxide, tin oxide, silicon aluminum oxide, cerium oxide, tungsten oxide, nickel tungsten oxide, and oxidized indium tin oxide. Carbides, nitrides, oxynitrides, and oxycarbides may also be used.Type: GrantFiled: March 2, 2020Date of Patent: January 24, 2023Assignee: View, Inc.Inventors: Sridhar Karthik Kailasam, Robin Friedman, Dane Thomas Gillaspie, Anshu A. Pradhan, Robert T. Rozbicki, Disha Mehtani

Patent number: 11559970Abstract: Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.Type: GrantFiled: August 19, 2020Date of Patent: January 24, 2023Assignee: View, Inc.Inventors: Fabian Strong, Yashraj Bhatnagar, Abhishek Anant Dixit, Todd Martin, Robert T.

Patent number: 11550197Abstract: Methods, apparatus, and systems for mitigating pinhole defects in optical devices such as electrochromic windows. One method mitigates a pinhole defect in an electrochromic device by identifying the site of the pinhole defect and obscuring the pinhole to make it less visually discernible. In some cases, the pinhole defect may be the result of mitigating a short-related defect.Type: GrantFiled: June 17, 2019Date of Patent: January 10, 2023Assignee: View, Inc.Inventors: Robin Friedman, Sridhar K.

Publication number: 20220413351Abstract: Resources of a system for controlling optically switchable windows may be used for a personal computing unit. The window system resources may include (i) a display associated with an optically switchable window, (ii) one or more processors of one or more controllers on a window network connected to a plurality of optically switchable windows in a building, wherein the one or more controllers are configured to vary tint states of the plurality of optically switchable windows in the building, (iii) memory of one or more controllers on the window network connected to the plurality of optically switchable windows in the building, and/or (iv) at least a part of the window network.Type: ApplicationFiled: August 30, 2022Publication date: December 29, 2022Inventors: Nitesh Trikha, Stephen Clark Brown, Dhairya Shrivastava, Robert T.

Publication number: 20220388900Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition. In certain embodiments, the device includes a counter electrode having an anodically coloring electrochromic material in combination with an additive.Type: ApplicationFiled: July 29, 2022Publication date: December 8, 2022Inventors: Anshu A.

Patent number: 11513412Abstract: A tintable window is described having a tintable coating, e.g., an electrochromic device coating, for regulating light transmitted through the window. In some embodiments, the window has a transparent display in the window's viewable region. Transparent displays may be substantially transparent when not in use, or when the window is viewed in a direction facing away from the transparent display. Windows may have sensors for receiving user commands and/or for monitoring environmental conditions. Transparent displays can display graphical user interfaces to, e.g., control window functions. Windows, as described herein, offer an alternative display to conventional projectors, TVs, and monitors. Windows may also be configured to receive, transmit, or block wireless communications from passing through the window. A window control system may share computational resources between controllers (e.g., at different windows).Type: GrantFiled: January 18, 2022Date of Patent: November 29, 2022Assignee: View, Inc.Inventors: Nitesh Trikha, Stephen Clark Brown, Dhairya Shrivastava, Robert T.
