ELECTRONIC DEVICE AND METHOD FOR DISPLAYING AUGMENTED REALITY

WIPO Patent Application WO/2021/002641

A1

An electronic device for displaying AR includes: an optical engine; a first polarizer; a polarization converter configured to maintain or convert a polarization direction of light of a real scene; a waveguide from which light of a virtual image is output and through which the light of the real scene is transmitted; a focus tunable lens; a second polarizer; and one or more processors. The one or more processors are configured to, during a first period, control the polarization converter to convert a polarization direction of a first light of the real scene such that at least part of the first light of the real scene is blocked by the second polarizer, and during a second period, control the polarization converter to maintain a polarization direction of a second light of the real scene such that the second light of the real scene is transmitted through the second polarizer.
