Publication number: 20240111169Abstract: A head-mounted display may include a display system and an optical system that are supported by a housing. The optical system may be a catadioptric optical system having one or more lens elements. The optical system may include a quarter wave plate that is coated to the first lens element without an intervening adhesive layer. The optical system may further include a reflective polarizer and a linear polarizer. The linear polarizer may be formed as a coating directly on the reflective polarizer (without an intervening adhesive). A single circular reflective polarizer may be used instead of a quarter wave plate and a reflective polarizer. The circular reflective polarizer may be coated to the first lens element without an intervening adhesive layer. The circular reflective polarizer may optionally provide optical power to the lens module. The circular reflective polarizer may include a cholesteric liquid crystal layer.Type: ApplicationFiled: December 15, 2023Publication date: April 4, 2024Inventors: Ran He, Francois R. Jacob, Zachary A. Granger, Brent J. Bollman

Publication number: 20230382085Abstract: An electronic device may have optical components that each have first and second transparent layers such as first and second glass layers. The glass layers may have outer surfaces that face away from each other and inner surfaces that face towards each other. A polymer layer is formed between the inner surfaces of the glass layers. Along the periphery of each optical component, a hermetic seal is formed to protect the polymer material of the polymer layer. The seal may have a moisture barrier layer that is attached to the first and second glass layers. The moisture barrier layer may be supported by an elastomeric buffer member. The moisture barrier layer may be formed from metal film or a polymer layer or other substrate that is coated with a moisture-impermeable coating. The moisture-impermeable coating may be formed from one or more thin-film metal layers and/or one more thin-film dielectric layers.Type: ApplicationFiled: August 9, 2023Publication date: November 30, 2023Inventors: Zachary M Beiley, Brent J Bollman, Derrick T Carpenter, Benjamin P Cherniawski, Boyi Fu, Nathan K Gupta, Wei Lin, Graham C Nelson, Isik I Nugay Ozel, Zhipeng Pan, Alexander D Schlaupitz, Kristina M Serratto, Ying-Da Wang, Da Yu, Tyler A Marshall

Publication number: 20230333359Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have a pixel array that produces light associated with images. The display system may also have a linear polarizer through which light from the pixel array passes and a quarter wave plate through which the light passes after passing through the quarter wave plate. The optical system may be a catadioptric optical system having one or more lens elements. The lens elements may include a plano-convex lens and a plano-concave lens. A partially reflective minor may be formed on a convex surface of the plano-convex lens. A reflective polarizer may be formed on the planar surface of the plano-convex lens or the concave surface of the plano-concave lens. An additional quarter wave plate may be located between the reflective polarizer and the partially reflective mirror.Type: ApplicationFiled: June 26, 2023Publication date: October 19, 2023Inventors: Sajjad A.

Publication number: 20230333390Abstract: A head-mounted display may include a display system and an optical system that are supported by a housing. The optical system may be a catadioptric optical system having one or more lens elements. In one example, the optical system includes a single lens element and a retarder that is coated on a curved surface of the lens element. The retarder may be coated on an aspheric concave surface of the lens element. In another example the retarder may be coated on an aspheric convex surface of the lens element. One or more components of the optical system may be formed using a direct printing technique. This may allow for one or more adhesive layers and one or more hard coatings to be omitted from the optical system. A lens element may be directly printed on the display system to improve alignment between the optical system and the display system.Type: ApplicationFiled: June 9, 2023Publication date: October 19, 2023Inventors: Ran He, Zuoqian Wang, Brent J. Bollman, Francois R. Jacob, Guanjun Tan, John N. Border, Serhan O. Isikman, Wei-Liang Hsu, Di Liu

Publication number: 20120104324Abstract: A precursor material for forming a film of a group IB-IIIA-chalcogenide compound and a method of making this film are disclosed. The film contains group IB-chalcogenide nanoparticles and/or group IIIA-chalcogenide nanoparticles and/or nanoglobules and/or nanodroplets and a source of extra chalcogen. Alternatively, the film may contain core-shell nanoparticles having core nanoparticles include group IB and/or IIIA elements, which are coated with a shell of elemental chalcogen material. The method of making a film of group IB-IIIA- chalcogenide compound includes mixing the nanoparticles and/or nanoglobules and/or nanodroplets to form an ink, depositing the ink on a substrate, heating to melt the extra chalcogen and to react the chalcogen with the group IB and group IIIA elements and/or chalcogenides to form a dense film.Type: ApplicationFiled: November 1, 2011Publication date: May 3, 2012Inventors: Jeroen K.

Patent number: 7829143Abstract: Organic films can be annealed by exposure to a solvent vapor. The solvent vapor annealing renders the organic film insoluble even in a solvent of a solution from which it was deposited. This enables deposition of two or more organic films in sequence without having one deposition alter an underlying organic film. Devices can be easily fabricated with organic films annealed in this manner when no other solution processing method is possible.Type: GrantFiled: November 21, 2003Date of Patent: November 9, 2010Assignee: Nanosolar, Inc.Inventors: Brent J. Bollman, Matthew R. Robinson

Patent number: 6987071Abstract: Spaces in a nanostructure can be filled with an organic material while in the solid state below Tm (without heating) by exposing the organic material to solvent vapor while on or mixed with the nanostructured material. The exposure to solvent vapor results in intimate contact between the organic material and the nanostructured material without having to expose them to possibly detrimental heat to melt in the organic material. Solution processing methods need only to be employed to create bulk films while organic material infiltration can take place in the solid state after depositing the film.Type: GrantFiled: November 21, 2003Date of Patent: January 17, 2006Assignee: Nanosolar, Inc.Inventors: Brent J. Bollman, Klaus Petritsch, Matthew R. Robinson
