摘要:
A near-eye display system (100) includes a display assembly (102) comprising at a display panel (110) and a display driver (122) to display a sequence (121) of frames in a low-persistence mode based on a frame clock signal (124) having a first frequency. The near-eye display system further includes a pair of liquid membrane lenses (112-1, 112-2) facing the display assembly, and a lens driver (114) coupled to the liquid membrane lenses, the lens driver to generate a periodic, continuously variable driving signal (116) 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, thus creating a perception to the user of multiple focal planes in the displayed imagery.
摘要:
A near-eye display system (100, 600) includes a display panel (102), a beam steering assembly (104) facing the display panel, a display controller (108), and a beam steering controller (110). 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.
摘要:
An optical apparatus for a head wearable display includes a lightguide, in-coupling holograms, and an out-coupling optical element. The lightguide includes an in-coupling region for receiving display light into the lightguide, an out-coupling region for emitting the display light out of the lightguide, and a relay region for guiding a path of the display light from the in-coupling region to the out-coupling region. A first of the in-coupling holograms is disposed at the in-coupling region to redirect the path of the display light by a first angle. A second of the in-coupling holograms is disposed across from the first in-coupling hologram at the in-coupling region to redirect the path of the display light by a second angle such that the path of the display light enters a total internal reflection condition in the relay region after redirection by the first and second in-coupling holograms.
