Abstract: A near-eye display system includes a display assembly comprising at least one display panel and a display driver to drive the display assembly to display a sequence of frames in a low-persistence mode based on a frame clock signal having a first frequency. The near-eye display system further includes a pair of liquid membrane lenses facing the display assembly, and a lens driver having an output coupled to an input of each of liquid membrane lenses of the pair, the lens driver to generate at the output a periodic, continuously variable driving signal having a second frequency, wherein the first frequency is an integer multiple of the second frequency. As the liquid membrane lenses are synchronized with the low-persistence display of the sequence of frames, each displayed frame is perceived through the liquid membrane lenses at a different nearly constant focal depth, and thus creating a perception to the user of multiple focal planes in the displayed imagery.

Abstract: A method of operation in a near-eye display system includes determining, using an eye tracking component of the near-eye display system, a pose of a user's eye. A shift vector is determined for a magnifier lens of the near-eye display system based on the pose of the user's eye, and the shift vector is communicated to an actuator of the near-eye display system to instruct translation of the magnifier lens relative to the user's eye. After translation of the magnifier lens, an array of elemental images is rendered at a position within a near-eye lightfield frame and communicated for display at a display panel of the near-eye display system.

Abstract: A near-eye display system includes a display panel to display a near-eye lightfield frame comprising an array of elemental images and an eye tracking component to track a pose of a user's eye. The system further includes a rendering component to position the array of elemental images within the near-eye lightfield frame based on the pose of the user's eye. A method of operation of the near-eye display system includes determining, using the eye tracking component, a first pose of the user's eye and determining a shift vector for an array of elemental images forming a near-eye lightfield frame based on the first pose of the user's eye. The method further includes rendering the array of elemental images at a position within the near-eye lightfield frame that is based on the shift vector.

Abstract: A lens assembly has two opposing surfaces, each surface introducing field curvature in a direction opposite of the field curvature introduced by the opposing surface, and thus the field curvatures introduced by the two surfaces at least partially cancel each other out, resulting in a net field curvature that provides for a substantially flat image plane or for an image plane with a specified curvature. The lens assembly may be implemented as a lens with two opposing Fresnel surfaces so that the field curvature in one direction introduced by one of the Fresnel surfaces is at least partially canceled out by the field curvature in the opposite direction as introduced by an opposing Fresnel surface. Alternatively, the lens assembly may be implemented as a lens with a positive continuous aspheric surface facing the user's eye and an opposing Fresnel surface facing the display panel.

Abstract: A near-eye display system includes a display panel, a beam steering assembly facing the display panel, a display controller, and a beam steering controller. The beam steering assembly imparts one of a plurality of net deflection angles to incident light. The display controller drives the display panel to display a sequence of images, and the beam steering controller controls the beam steering assembly to impart a different net deflection angle for each displayed image of the sequence. The sequence of images, when displayed within the visual perception interval, may be perceived as a single image having a resolution greater than the resolution of the display panel or having larger apparent pixel sizes that conceal the black space between pixels of the display, or the sequence of images may represent a lightfield with the angular information represented in the net deflection angles imparted into the images as they are projected.
