Patent number: 11719953Abstract: A method for collimating light using a film including elongated chambers of bistable electrophoretic fluids. The light-collimating films are suitable to control the amount and/or direction of light incident to a transmissive substrate. Such films may be integrated into devices, such as LCD displays, to provide a zone of privacy for a user viewing the LCD display. Because the light-collimating film is switchable, it allows a user to alter the collimation of the emitted light on demand. Because the films are bistable, they do not require additional power after they have been switched to a display state.Type: GrantFiled: March 23, 2022Date of Patent: August 8, 2023Assignee: E INK CALIFORNIA, LLCInventors: Xiaolong Zheng, Pubudu Thilanka Galwaduge, Craig Lin, Yih-Ming Kang, HongMei Zang, Hui Du
