  • Publication number: 20240345398
    Abstract: An optical assembly for head wearable display includes a light redirecting layer, provided in a first optical path between a first light emitter and a first eye of a viewer, the light redirecting layer including a plurality of three dimensional geometric patterns that are cyclically provided on one surface of the light redirecting layer. The light redirecting layer includes a plurality of subunit sections, each of the plurality of subunit sections respectively includes the plurality of three dimensional geometric patterns with different physical dimensions for respectively receiving and redirecting light emission of different wavelengths of a first light signal emitted by the first light emitter toward the first eye of the viewer with different incident angles, the first light signal corresponds to a first pixel of an image. The plurality of three dimensional geometric patterns include pillar like three dimensional nanostructure protruding from a surface of the light redirecting layer.

  • Patent number: 12111472
    Abstract: The present disclosure relates to an optic system for head wearable devices. The optic system comprises a first light emitter for emitting a plurality of first light signals, the first light emitter varies a direction of projection between a first spatial dimension limit and a second spatial dimension limit in a first dimension; a first light redirector; and a second light redirector. A geometry of the first light redirector is configured such that a light signal emitted by the first light emitter in proximity to the first spatial dimension limit has a total optical path length from the first light emitter to the eye of the viewer substantially equal to a total optical path length of another light signal emitted by the first light emitter in proximity to the second spatial dimension limit from the first light emitter to the eye of the viewer.
