Abstract: In an embodiment, an electronic device includes a display and processing circuitry. The display includes a plurality of pixels arranged in a plurality of rows, wherein a first grouping of the plurality of rows displays image content during a first portion of an image frame, and wherein a second grouping of the plurality of rows displays image content during a second portion of the image frame. The processing circuitry is operatively coupled to the display and determines a velocity associated with the image content displayed by the first grouping of the plurality of rows moving across the display and adjusts a position of the image content displayed by the second grouping of the plurality of rows during the second portion of the image frame.

Abstract: An electronic device may include a display panel configured to produce light and a lens assembly that receives the light from the display panel. The lens assembly may include a first lens and a second lens. The second lens may be a removable lens that is configured to be selectively attached to the lens assembly. The lens assembly may also include a partially reflective mirror that is interposed between the first lens and the display panel, a reflective polarizer that is interposed between the first lens and the second lens when the second lens is attached to the lens assembly, and a quarter wave plate that is interposed between the reflective polarizer and the second lens when the second lens element is attached to the lens assembly.

Abstract: A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. A twisted nematic cell may be optically interposed between the fLCOS panel and the waveguide. A birefringent crystal may be optically interposed between the cell and the waveguide. The cell may have a first state in which the cell transmits the image light with a first polarization and a second state in which the cell transmits the image light with a second polarization. The crystal may transmit the image light within spatially offset beams based on polarization. In another arrangement, a quarter waveplate may be optically interposed between the cell and the waveguide and a geometric phase grating may be optically interposed between the quarter waveplate and the waveguide. Control circuitry may toggle the cell between the first and second states to maximize the effective resolution of images at an eye box.

Abstract: Embodiments presented herein relate to reducing visual artifacts on an electronic display caused by an intra-frame pause. To do so, the intra-frame pause may be divided into smaller intra-frame pause segments. The intra-frame pause segments may be applied to the display during different image frames and/or at different locations on the electronic display. For example, each intra-frame pause segment may be applied to a different location on the electronic display. In some embodiments, multiple intra-frame pause segments may be applied during a single image frame. In some embodiments, the intra-frame pause segments may be applied to various image frames and at various location on the electronic display according to a pattern. To reduce band flickering that may be caused by the different locations of the intra-frame pause segments, an emission duty of one or more rows of pixels of the display may be adjusted.

Abstract: The present invention relates to a virtual image distance measurement method, apparatus and device. The method includes: disposing a light blocking element, a lens element and an imaging element along the optical axis of the lens element in sequence, wherein a light transmitting portion is formed on the light blocking element, and the virtual image position of a measured near-eye display does not coincide with the imaging position of the lens element; presenting, by a virtual image of the measured near-eye display, multiple images on the imaging element after passing through the light blocking element and the lens element; and determining a distance measurement parameter based on the multiple images, and substituting the distance measurement parameter into a preset distance calculation formula to obtain a virtual image distance.
