METHOD AND APPARATUS FOR A NEAR-TO-EYE DISPLAY |
摘要 |
An eyepiece for a head mounted display includes an illumination module, an end reflector, a viewing region, and a polarization rotator. The illumination module provides CGI light along a forward propagation path within the eyepiece. The end reflector is disposed at an opposite end of the eyepiece from the illumination module to reflect the CGI light back along a reverse propagation path within the eyepiece. The viewing is disposed between the illumination module and the end reflector and includes an out-coupling polarizing beam splitter (“PBS”). The out-coupling PBS passes the CGI light traveling along the forward propagation path and redirects the CGI light traveling along the reverse propagation path out of an eye-ward side of the eyepiece. The polarization rotator is disposed in the forward and reverse propagation paths between the out-coupling PBS and the end reflector. |
