DYNAMIC LENS FOR HEAD MOUNTED DISPLAY

摘要

A Head Mounted Display (“HMD”) includes a display module, an optical combiner, control circuitry, and a lens. The display module generates image light and the optical combiner is for combining the image light with external scene light. The lens is positioned to receive the image light. The lens is capable of dynamically changing at least one lens property of the lens. The control circuitry controls the lens to dynamically change at least one lens property of the lens.
