The waveguide may include an in-coupling element that may selectively couple one or more optical streams from the multiplexed optical stream into the waveguide while emitting one or more other optical streams from the multiplexed optical stream.

In one embodiment, the device described in the patent includes at least one processor. The processor is configured to determine the target coupling output surface, identify the optical path to the target coupling output surface, identify the active wave plate corresponding to the optical path, and determine the optical path corresponding to the optical path. a target state of the active wave plate, setting the active wave plate to the identified target state, and causing the projection device to project a light beam including the image field component along the identified optical path.
In one embodiment, the patent describes a method for generating images in a near-eye display. The method may include operating a light source to emit an image as incident light. The light source may be configured such that incident light received by the light reflective element compensates for the color reflectivity of the light reflective element. The method may include coupling incident light into a light-transmissive substrate such that the light is trapped by total internal reflection between a first major surface and a second major surface of the light-transmissive substrate and by a light reflective element having a colored reflectivity Couple the light out of the substrate.
In one embodiment, the patent describes an optical waveguide comprising: a substrate arranged to guide an optical image inside the substrate from an inlet to an outlet of the optical waveguide via a plurality of reflections; at the inlet or outlet of the optical waveguide a surface relief grating that guides the image in the optical waveguide via diffraction and includes a plurality of grooves; a coating disposed on the surface relief grating and at least partially filling at least one groove . The at least one groove is provided at an edge of the surface relief grating at which the image coincides with the at least one groove after a first reflection of the image inside the substrate, the paint having a The optical properties of the substrate converge to the optical properties.
In one embodiment, the method described in the patent includes: determining candidate gratings; determining a combination of gratings based on the candidate gratings, wherein each of the grating combinations includes at least one of the candidate gratings, and in each grating The at least one of the candidate gratings in the combination is different from each other; determining a first diffraction response map of a first multiplexed grating corresponding to a first grating combination of the grating combination; by modifying the first multiplexed grating based on at least one parameter of the light engine. a diffraction response map to determine a first luminous intensity map of the first multiplexed grating corresponding to the first grating combination; and determining a first reconstructed image corresponding to the light engine by processing the template image based on the first luminous intensity map.
In one embodiment, the display device control method described in the patent includes: obtaining, by the processor, information related to the display device, wherein the information includes processor usage of the processor, display status, the wearing status of the display, the noise data of the heat dissipation unit, the rotation speed data of the heat dissipation unit, or any combination thereof; and through the processor, control the system sound and the heat dissipation unit according to the information related to the display device At least one of, wherein the system sound is configured to be generated by a sound output unit.
