    摘要: An optical device is provided, including a body formed to have a concavity within which an eye box region is defined; and a plurality of addressable vertical cavity surface emitting laser (VCSEL) arrays arranged in the body of the optical device. The one or more VCSEL arrays comprise a plurality of VCSEL subarrays including independently addressable first and second VCSEL subarrays, which are controlled so as to power the first VCSEL subarray and not the second VCSEL subarray to illuminate only a first subregion of the eye box region, or to power the second VCSEL subarray and not the first VCSEL subarray to only illuminate a second subregion of the eye box region.

    摘要: The present disclosure concerns a near-eye light-field display system comprising an emissive display (1), containing a plurality of display pixels (10, 12), each display pixel (10, 12) having color information and being individually addressable to be set inactive or active where it generate a light beam (111); and a lens array (14) comprising an array including a plurality of lenses (140) and configured to project the light beams (111) of the active display pixels (10, 12) to form a projection virtual pixel image (26). The projection pixel image (26) having color information and a position in space that are determined by the number of the active display pixels (10, 12) and their position on the emissive display (1). The present disclosure further concerns a method of projecting a projection virtual pixel using the near-eye light-field display system.

    摘要: A display unit of the present disclosure includes: a light source section that outputs light; a light uniformization section including at least one uniformization optical member and having a light entrance surface through which the light outputted from the light source section enters and a light output surface through which light is outputted; a condenser lens for the light outputted from the light uniformization section to enter; and a reflective light valve to be illuminated by light outputted from the condenser lens. A light condensing position for return light that is reflected by the light valve and returns to the light output surface of the light uniformization section via the condenser lens is configured to be located off a light condensing position of the light uniformization section on a light output surface side for the light outputted from the light source section.

    摘要: Described are various embodiments of a digital display device for use by a user having reduced visual acuity. In one embodiment, the device comprises: a digital display medium comprising an array of pixels and operable to render a pixelated image accordingly; a light field shaping layer defined by an array of light field shaping elements and disposed relative to said digital display so to align each of said light field shaping elements with a corresponding set of said pixels to shape a light field emanating therefrom and thereby at least partially govern a projection thereof from said display medium toward the user; and a hardware processor operable on pixel data for the image such that said processed image is rendered to at least partially compensate for the user’s reduced visual acuity.
