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.
