Abstract: A method of planarizing an overcoat layer on a surface-relief grating includes dispensing a layer of a resin material that is curable by heat or electromagnetic radiation on a surface-relief grating that includes a plurality of grating grooves, pressing the layer of the resin material using a planar imprint stamp, curing the resin material in the layer of the resin material, and detaching the planar imprint stamp from the layer of the resin material. In one example, a thickness of the overcoat layer on top of grating ridges of the surface-relief grating is equal to or less than 20 nm, and a surface peak-to-valley height of a top surface of the overcoat layer is equal to or less than 5 nm.

Abstract: Aspects of the disclosure are directed to an artificial reality (XR) browser configured to trigger an immersive experience. Implementations display an element at a browser chrome of the XR browser when an immersive experience is loaded. For example, the XR browser can include an application programming interface (API) that supports configuration of a browser chrome element by components of a webpage. The API call can cause the display of the browser chrome element, change a display property for the browser chrome element, or configure the browser chrome element in any other suitable manner. Upon receiving input at the browser chrome element (configured by the API call), the XR browser can transition from displaying a two-dimensional panel view of a webpage supported by loaded web resources (e.g., hypertext transfer protocol (HTTP) pages, graphic images, etc.) to a three-dimensional environment supported by preloaded immersive resources (e.g., three-dimensional models, graphic images, etc.).

A headset using a controller that includes a lanyard as above, and the controller, are also provided.

Abstract: Augmented and/or virtual reality (AR/VR) near-eye display devices implementing large field of view (FOV) waveguide (WG) eye tracking combined with switchable/tunable optical elements to enable both eye and face tracking are disclosed. In particular, an eye tracking system for an augmented reality/virtual reality (AR/VR) display device may comprise a waveguide, a first deflector element to reflect captured light to propagate in the waveguide, a second deflector element to reflect the propagated light out of the waveguide, an optical element to guide out-coupled light into an eye tracking camera, and a controller to manage the optical element such that a small FOV image of an eye is captured in a first time frame and a large FOV image of a region around the eye is captured in a second time frame.

Abstract: A reflective polarization volume hologram (rPVH) layer in combination with a quarter wave plate (QWP) is used to provide optical power and to correct chromatic aberration in an optical assembly of an augmented and/or virtual reality (AR/VR) near-eye display device. The rPVH layer introduces more degrees of freedom to further improve contrast of the optical system and reduces a thickness/weight of the optical assembly. The rPVH layer is flexible, thus, allowing curved lamination on an optical lens. Moreover, the rPVH layer is sensitive to circular polarization. Thus, it can filter right-handed circular polarization (RHCP) or left-handed circular polarization (LHCP), without a need for the QWP.

Abstract: According to examples, a display system may include a wearable eyewear arrangement that may include a lens assembly having a projector to propagate display light associated with an image. The lens assembly may also include a waveguide configuration for propagating the display light to an eyebox. The waveguide configuration may include a volume Bragg grating (VBG) component for propagating the display light from a projector to an eyebox. The VBG component may include at least one tilt adjusted grating facilitated by adjustment in an original grating vector (k) direction of a grating by a pre-determined value. The tilt adjusted grating may facilitate to mitigate a rainbow effect observable in a gazing direction of the eyebox. The rainbow effect may be mitigated by modification of a rainbow ghost path away from the gazing direction without affecting propagation of the image pertaining to the display light.

Abstract: Haptic actuators may include a first active material coupled to a first side of an inactive substrate and a second active material coupled to a second side of the inactive substrate.

Various other methods, systems, and devices are also disclosed.

Abstract: A power management system for a display light emitting diode (LED) driver for an augmented reality/virtual reality (AR/VR) device mitigates (e.g., attenuates) an input peak power delivered to the LED driver from a DC source and decreases a voltage ramp rate of the LED driver while maintaining the default current ramp rate or vice versa. A liquid crystal on silicon (LCOS) digital process is used to provide a current reference with a slow ramp rate and/or to provide an offset. The offset (e.g., a delay) may be implemented between the voltage ramp and the current ramp to achieve a non-overlapping output voltage and output current.

The first optical element receives the second image light from the second optical element and sends the second image light back toward the second optical element, and the second optical element receives and transmits the second image light from the first optical element.

Abstract: Sharpening of images in organic light emitting diode (OLED) displays through high pass filtering of edge data and use of additional line memory in display stream compression (DSC) part of a display driving integrated circuit (DDIC) is described herein. A system according to examples may locate edge points of line data by computing a difference between prediction data and filtered data, and adjust (e.g., add or subtract weights) the prediction data by comparing the computed difference with a predefined threshold. In some examples, a Sobel filter may be used with an additional line memory in the display stream compression (DSC) to obtain improved edge information. In other examples, the display stream compression (DSC)'s flatness check function may be used to identify and/or confirm edge data before adding or subtracting weights.

The index-gradient antireflective coating can be fabricated using a non-uniform spin-coating process, by successive thermal evaporation, or by a chemical vapor deposition (CVD) process. In another embodiment, the spin-coating process can include multiple steps that include different concentrations of monomers to solvent, different spin-speeds, or different annealing times/temperatures. Similarly, the thermal evaporation can include multiple steps that include different concentrations of monomers, initiators, solvents, and associated processing parameters.
