Abstract: A method of forming an organic solid crystal (OSC) thin film includes forming a layer of a non-volatile medium material over a surface of a mold, forming a layer of a molecular feedstock over a surface of the non-volatile medium material, the molecular feedstock including an organic solid crystal precursor, forming crystal nuclei from the organic solid crystal precursor, and growing the crystal nuclei to form the organic solid crystal thin film. An organic solid crystal (OSC) thin film may include a biaxially-oriented organic solid crystal layer having mutually orthogonal refractive indices, n1≠n2≠n3.

Abstract: A method of forming a uniaxially oriented crystalline polymer article includes heating a segment of a crystallizable polymer article to a first temperature, applying a stress to the crystallizable polymer article in an amount effective to induce a positive strain within the segment of the crystallizable polymer article, and heating the segment of the crystallizable polymer article to a second temperature greater than the first temperature while continuing to apply the stress.

Abstract: An eye is illuminated with infrared illumination light. Illuminating the eye includes illuminating a near-eye ellipsoidal lensing structure. A tracking image of Purkinje reflections of the infrared illumination light is captured by a camera. An eye position of the eye is determined in response to the tracking image.

Abstract: A display system may include a light source that emits input light having a wavelength within a source wavelength range and an array of color conversion units overlapping a display area. A first set of color conversion units of the array of color conversion units may include a first color conversion medium that converts the input light to a first color of light having a wavelength within a first wavelength range that is different than the source wavelength range. The display system may also include a waveguide having an out-coupler that directs the input light from the light source toward the array of color conversion units. Various other devices, systems, and methods are also disclosed.

Abstract: A display device includes a display panel including a first array of light emitters having a first spacing in a first emission region of the display panel and a second array of light emitters having a second spacing in a second emission region of the display panel. The second spacing is distinct from the first spacing. The display device includes an optical filter including a first filter region and a second filter region. The first filter region changes distribution of first light from the first array of light emitters impinging on the first filter region so that the first light has a first distribution after passing through the first filter region. The second filter region changes distribution of second light from the second array of light emitters impinging on the second filter region so that the second light has a second distribution after passing through the second filter region.

Abstract: A liquid lens includes a transparent substrate, a multilayer polyurethane-based membrane overlying the transparent substrate, and a liquid layer disposed between and abutting the transparent substrate and the multilayer polyurethane-based membrane. The multilayer polyurethane-based membrane, which may include thermoplastic and/or thermoset polymer layers, may be formed by slot die coating or gravure coating one or more constituent layers and may exhibit a reversible elastic response to imposed strains of up to approximately 5% while limiting the transpiration of fluid therethrough to less than approximately 10−2 g/m2/day.

Abstract: A method may include bonding a deformable bounding element to a structural support element in which the deformable bounding element and a cavity-adjacent side of the structural support element define a cavity. The method may further include filling the cavity with a deformable medium by injecting the deformable medium past a cavity-opposite side of the structural support element and toward the cavity-adjacent side of the structural support element. The method may additionally include sealing an entry point of the injection of the deformable medium into the cavity. Various other apparatuses, systems, and methods are also disclosed.

Abstract: A pupil-replicating lightguide includes a slab of transparent material, a switchable out-coupling grating for out-coupling portions of image light to propagate towards an eyebox, and a switchable tracking grating for redirecting tracking light carrying an eye image towards an eye tracking camera. One of the two gratings may be turned ON while the other is turned OFF, in a time-sequential manner, allowing the combined use of the pupil-replicating lightguide for carrying image light and eye tracking light.

Abstract: A multilayer reflective polarizer includes a layer of a birefringent organic solid crystal, where the birefringent organic solid crystal has a refractive index of at least approximately 1.5 and a birefringence of at least approximately 0.1. The multilayer reflective polarizer may be configured to include alternating layers of a birefringent organic solid crystal material and a secondary material layer selected from an amorphous polymer, an inorganic amorphous compound, a liquid crystal, and an OSC material. The refractive index of the birefringent organic solid crystal layer(s) may be modified through the application of an applied voltage, current, or stress.
