Retinal Resolution and Single-Chip Multiplexed Image Transfer for AR Near-to-Eye Displays
Tech ID: UA20-103
This invention is a single-chip, field of view (FOV) selective, and variable resolution image projection design for augmented reality near-to-eye displays (AR-NEDs). The design includes a multiplexed full color image transfer via single image guide, to achieve design requirements such as full color, 90 degrees FOV, and retinal image resolution.
For mobile augmented reality near-to-eye displays (AR-NEDs), reduction of size, weight, cost, and power of display optics is highly anticipated while increasing resolution, field of view (90 degrees in horizontal full FOV), optical efficiency, and the eye box size to accommodate FOV. Among display components/optics, holographic waveguide employed for AR-NED is one of the bottle necks that limits FOV up to several tens of degrees per single color. Moreover, pixel counts exceed the state-of-the-art of micro displays if the entire FOV of 90 degrees supports retinal resolution. Headsets are currently being used widely for entertainment, creative purposes, designing, medicine, therapy, business management and training. The result of this tech is that it demonstrates power efficient, full color, retinal resolution, and 90 degree FOV display within a single layer waveguide design.
