Publication number: 20240194106Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To mitigate artifacts caused by a light emitter operating through a display, the display may have a higher density of thin-film transistor sub-pixels than emissive sub-pixels. This allows for a region in the display to include emissive sub-pixels but be free of thin-film transistor sub-pixels. The light emitter may operate through this region in the display. Additionally, to reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels.Type: ApplicationFiled: September 28, 2023Publication date: June 13, 2024Inventors: Shyuan Yang, Cheng-Chih Hsieh, Jonathan H. Beck, Yuchi Che, Tsung-Ting Tsai, Warren S. Rieutort-Louis, Abbas Jamshidi Roudbari, Ting-Kuo Chang, Shih Chang Chang, Bhadrinarayana Lalgudi Visweswaran, Jae Won Choi, Kyounghwan Kim

Publication number: 20240157642Abstract: The present disclosure provides apparatuses and methods for manufacturing three-dimensional objects. Each additive manufacturing apparatus (1000, 2000, 3000) includes: a) a reservoir (1100, 2100, 3100) for receiving hardenable material; b) a first movable light engine (1200, 2200, 3200) providing a first light radiation configuration; a second light engine (1300, 2300, 3300) providing a second light radiation configuration that is different than the first light radiation configuration; and d) a light altering structure (1400, 2400, 3400). The light altering structure is located between the reservoir and light radiated from at least one of the first movable light engine or the second light engine. The first movable light engine is configured to radiate light onto a first focal plane (2220) within the reservoir containing the hardenable material and the second light engine is configured to radiate light onto a second focal plane (2320) within the reservoir containing the hardenable material.Type: ApplicationFiled: February 23, 2022Publication date: May 16, 2024Inventors: Malte KORTEN, Nicholas S.

Patent number: 11714284Abstract: An augmented reality headset may include a reflective holographic combiner to direct light from a light engine into a user's eye while also transmitting light from the environment. The combiner and engine may be arranged to project light fields with different fields of view and resolution to match the visual acuity of the eye. The combiner may be recorded with a series of point to point holograms; one projection point interacts with multiple holograms to project light onto multiple eye box points. The engine may include a laser diode array, a distribution waveguide, scanning mirrors, and layered waveguides that perform pupil expansion and that emit wide beams of light through foveal projection points and narrower beams of light through peripheral projection points. The light engine may include focusing elements to focus the beams such that, once reflected by the holographic combiner, the light is substantially collimated.Type: GrantFiled: December 30, 2021Date of Patent: August 1, 2023Assignee: Apple Inc.Inventors: Richard J. Topliss, Paul J. Gelsinger-Austin, Thomas M. Gregory, Richard H. Tsai, Alexander Shpunt

Patent number: 11695913Abstract: A mixed reality direct retinal projector system that may include a headset that uses a reflective holographic combiner to direct light from a light engine into an eye box corresponding to a user's eye. The light engine may include light sources coupled to projectors that independently project light to the holographic combiner from different projection points. The light sources may be in a unit separate from the headset that may be carried on a user's hip, or otherwise carried or worn separately from the headset. Each projector may include a collimating and focusing element, an active focusing element, and a two-axis scanning mirror to project light from a respective light source to the holographic combiner. The holographic combiner may be recorded with a series of point to point holograms; each projector interacts with multiple holograms to project light onto multiple locations in the eye box.Type: GrantFiled: September 10, 2021Date of Patent: July 4, 2023Assignee: Apple, Inc.Inventors: Richard J.
