Title:
OPTICAL DISPLAY SYSTEM AND ELECTRONICS DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/174405
Kind Code:
A1
Abstract:
An optical display system and an electronics device are disclosed. The optical display system comprises: a display, which generating image light of a first polarization; a partial reflector (3), which transmits the image light without changing its polarization and reflects the image light with its polarization being changed to a second polarization; a first optic unit (4), placed after the partial reflector (3), which includes at least one refractive lens for chromatic aberration correction; and a reflection-type Pancharatnam-Berry lens (5), which is placed after the first optic unit (4) and works in the Bragg regime, and which reflects the image light of the first polarization and transmits the image light of the second polarization.
