US 12,007,651 B2 · Virtual reality display

Abstract

A virtual reality display includes a display module and an optical module. The display module includes a display, a liquid crystal cell, a first phase retarder, and a polarizing directional lens. The optical module includes a transflective lens, a second phase retarder, a reflective polarizer, and a lens element. The liquid crystal cell is located between the display and the first phase retarder, and the polarizing directional lens is located between the first phase retarder and the transflective lens. The transflective lens is located between the polarizing directional lens and the second phase retarder, and the reflective polarizer is located between the second phase retarder and the lens element.
