摘要： A display article is described herein that includes: a substrate comprising a thickness and a primary surface; a textured surface region; and an antireflective coating disposed on the textured surface region. The textured surface region comprises structural features and an average texture height (Rtext) from 50 nm to 300 nm. The substrate exhibits a sparkle of less than 5%, as measured by PPD140, and a transmittance haze of less than 40%, at a 0˚ incident angle. The antireflective coating comprises alternating high refractive index and low refractive index layers. Each of the low index layers comprises a refractive index of less than or equal to 1.8, and each of the high index layers comprises a refractive index of greater than 1.8. The article also exhibits a first-surface average photopic specular reflectance (%R) of less than 0.3% at any incident angle from about 5˚ to 20˚ from normal at visible wavelengths.

摘要： A method of displaying a target light field using an image-replicating combiner is described. The method comprises determining a target light field to be displayed at a viewing location;determining a transfer function describing the propagation of light through the image-replicating combiner between the viewing location and an input location near to an input surface of the image-replicating combiner; determining an input light field by applying the determined transfer function to the target light field; and displaying the input light field at the input location. A display system to display a target light field is also described.

摘要： In example embodiments, an apparatus includes a waveguide having an in-coupler, an out-coupler, and at least one exit pupil expander along an optical path from the in-coupler to the out-coupler. A holographic optical element is provided on a surface of the waveguide substantially opposite the exit pupil expander. The holographic optical element being configured to selectively reflect light having a first characteristic and to selectively transmit light that does not have the first characteristic. The first characteristic may include light having an incident angle greater than a threshold angle, light having a propagation direction along the optical path from the in-coupler to the out-coupler, and/or light having a selected wavelength.
