Patent number: 11960165Abstract: A display device comprises a waveguide configured to guide light in a lateral direction parallel to an output surface of the waveguide. The waveguide is further configured to outcouple the guided light through the output surface. The display device additionally comprises a broadband adaptive lens assembly configured to incouple and to diffract therethrough the outcoupled light from the waveguide. The broadband adaptive lens assembly comprises a first waveplate lens comprising a liquid crystal (LC) layer arranged such that the waveplate lens has birefringence (?n) that varies in a radially outward direction from a central region of the first waveplate lens and configured to diffract the outcoupled light at a diffraction efficiency greater than 90% within a wavelength range including at least 450 nm to 630 nm. The broadband adaptive lens assembly is configured to be selectively switched between a plurality of states having different optical powers.Type: GrantFiled: January 24, 2022Date of Patent: April 16, 2024Assignee: MAGIC LEAP, INC.Inventors: Chulwoo Oh, Ravi Kumar Komanduri, Roy Matthew Patterson, Charles Scott Carden, Michael Nevin Miller, Vikramjit Singh

Patent number: 11921290Abstract: A display device includes a waveguide assembly comprising a waveguide configured to outcouple light out of a major surface of the waveguide to form an image in the eyes of a user. An adaptive lens assembly has a major surface facing the output surface and a waveplate lens and a switchable waveplate assembly. The switchable waveplate assembly includes quarter-wave plates on opposing sides of a switchable liquid crystal layer, and electrodes on the quarter-wave plates in the volume between the quarter-wave plates. The electrodes can selectively establish an electric field and may serve as an alignment structure for molecules of the liquid crystal layer. Portions of the adaptive lens assembly may be manufactured by roll-to-roll processing in which a substrate roll is unwound, and alignment layers and liquid crystal layers are formed on the substrate as it moves towards a second roller, to be wound on that second roller.Type: GrantFiled: January 8, 2021Date of Patent: March 5, 2024Assignee: Magic Leap, Inc.Inventors: Roy Matthew Patterson, Chulwoo Oh, Ravi Kumar Komanduri, Charles Scott Carden, Michael Nevin Miller, Vikramjit Singh, Shuqiang Yang

Patent number: 11886000Abstract: In some embodiments, a head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting. The spacers are disposed on one major surface of each of the waveguides and indentations are provided on an opposite major surface of each of the waveguides. The indentations are sized and positioned to align with the spacers, thereby forming a self-aligned stack of waveguides. Tops of the spacers may be provided with light scattering features, anti-reflective coatings, and/or light absorbing adhesive to prevent light leakage between the waveguides. As seen in a top-down view, the spacers may be elongated along the same axis as the diffractive optical elements. The waveguides may include structures (e.g.Type: GrantFiled: April 1, 2019Date of Patent: January 30, 2024Assignee: Magic Leap, Inc.Inventors: Christophe Peroz, Chieh Chang, Sharad D.
