Patent number: 11940639Abstract: In some implementations, an optical device includes a one-way mirror formed by a polarization selective mirror and an absorptive polarizer. The absorptive polarizer has a transmission axis aligned with the transmission axis of the reflective polarizer. The one-way mirror may be provided on the world side of a head-mounted display system. Advantageously, the one-way mirror may reflect light from the world, which provides privacy and may improve the cosmetics of the display. In some implementations, the one-way mirror may include one or more of a depolarizer and a pair of opposing waveplates to improve alignment tolerances and reduce reflections to a viewer. In some implementations, the one-way mirror may form a compact integrated structure with a dimmer for reducing light transmitted to the viewer from the world.Type: GrantFiled: March 24, 2021Date of Patent: March 26, 2024Assignee: Magic leap, Inc.Inventors: Chulwoo Oh, Ravi Kumar Komanduri, David Kleinman, Vaibhav Mathur, David Manly

Publication number: 20240027804Abstract: An electronic eyewear device including a spatial dimming pixel panel within an optical assembly that delivers improved backlighting conditions for displayed images. The spatial dimming pixel panel is spatially dimmed where an image is positioned on a display, and the unoccupied area of the display is not dimmed (undimmed), thereby unaltering the real-world view through that portion of the display. The spatial dimming pixel panel is made of multiple liquid crystal cells arranged in a gridded orientation with a dye-doped or guest-host liquid crystal system having a phase change mode with homeotropic alignment. The spatial dimming pixel panel absorbs nonpolarized light when a voltage is applied across the cells and passes nonpolarized light in the absence of a voltage across the cells.Type: ApplicationFiled: July 22, 2022Publication date: January 25, 2024Inventors: Vaibhav Mathur, Miller Schuck, Mario Matranga

The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include determining a fixation point of a user's eyes. Location information associated with a first virtual object to be presented to the user via a display device is obtained. A resolution-modifying parameter of the first virtual object is obtained. A particular resolution at which to render the first virtual object is identified based on the location information and the resolution-modifying parameter of the first virtual object. The particular resolution is based on a resolution distribution specifying resolutions for corresponding distances from the fixation point. The first virtual object rendered at the identified resolution is presented to the user via the display system.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Inventors: Vaibhav MATHUR, Lionel Ernest EDWIN, Xiaoyang ZHANG, Bjorn Nicolaas Servatius VLASKAMP

Publication number: 20230314825Abstract: A wearable display system includes an eyepiece stack having a world side and a user side opposite the world side, wherein during use a user positioned on the user side views displayed images delivered by the system via the eyepiece stack which augment the user’s view of the user’s environment. The wearable display system also includes an angularly selective film arranged on the world side of the of the eyepiece stack. The angularly selective film includes a polarization adjusting film arranged between pair of linear polarizers.
