Patent number: 12276796Abstract: A head-mounted display device employs light field directional backlighting to provide three-dimensional (3D) pupil steering without mechanical adjustment while maintaining a compact form factor and performance. An example light field directional backlighting unit includes two substantially flat components: an array of light sources and an array of modulators (e.g., a micro lens array (MLA), a stack of transmissive display elements, a pinhole array, and similar ones). By digitally modifying the illumination pattern on the array of light source and pairing to the light field directional backlighting unit to an extra transmissive display element as the main display panel and one or more viewing optical elements, a light field created by the light field directional backlighting unit is moved in three-dimensional (3D) space to correspond to pupil shift without interfering with the display content.Type: GrantFiled: December 2, 2022Date of Patent: April 15, 2025Assignee: Meta Platforms Technologies, LLCInventors: Hekun Huang, Xuan Wang, Sascha Hallstein

Patent number: 12271078Abstract: Embodiments of the present disclosure relate to a high performance backlight device with photonic integrated circuits. The backlight device includes a light source assembly, a multi-mode slab waveguide, and an out-coupling assembly. The light source assembly includes one or more light sources that generate light in accordance with emission instructions, and a de-speckling mechanism that conditions the generated light to mitigate speckle. The multi-mode slab waveguide in-couples the conditioned light and expands the in-coupled conditioned light in two dimensions to form a homogenous area of conditioned light within a region of the multi-mode slab waveguide. The out-coupling assembly out-couples the conditioned light from the region in a direction normal to the two dimensions, wherein a light modulation layer forms an image from the out-coupled conditioned light.Type: GrantFiled: November 10, 2022Date of Patent: April 8, 2025Assignee: Meta Platforms Technologies, LLCInventors: Zhimin Shi, James Ronald Bonar, Wanli Chi
