Patent number: 12078803Abstract: A near-eye display (NED) includes a source assembly, a waveguide outside a field-of-view of a user, and a main optic within the field-of-view. The waveguide expands light emitted from the source assembly in at least one dimension and out-couple the expanded light. The main optic is partially transparent and is positioned such that the user of the NED looks through the main optic to view a local area surrounding the NED. The main optic receives light from the local area, combines the received light with the expanded light to generate combined light, and directs the combined light to the user's eye-box.Type: GrantFiled: December 15, 2020Date of Patent: September 3, 2024Assignee: META PLATFORMS TECHNOLOGIES, LLCInventor: Nicholas Daniel Trail

Patent number: 12050319Abstract: The invention discloses an optical-waveguide display module with multiple light sources, including a light-source array of timing-orthogonal-characteristic, a relay device, a display device of orthogonal-characteristic, an optical waveguide device, a converging device, a control device, and other components. The light-source array of timing-orthogonal-characteristic includes more than one orthogonal-characteristic light sources. All orthogonal-characteristic light sources are switched on and off in each time cycle sequentially, with only one orthogonal-characteristic light source being switched on at a time-point of each time cycle. By designing the spatial distribution of converging spots of lights from different orthogonal-characteristic light sources, one two-dimensional image is projected into the pupil of the viewer in each time cycle, which realizes VAC-free three-dimensional display based on Maxwellian view technology or More-than-one-view-one-pupil technology.Type: GrantFiled: August 30, 2021Date of Patent: July 30, 2024Assignee: SUN YAT-SEN UNIVERSITYInventors: Dongdong Teng, Lilin Liu
