Abstract
An optical displaying system includes a display screen; a first light splitting unit, wherein a light ray emitted by the display screen is converted into a first-type polarized light or a second-type polarized light after passing through the first light splitting unit; an imaging unit, wherein a light ray exiting from the first light splitting unit forms an enlarged image corresponding to a first focal length after passing through the imaging unit; a second light splitting unit; a first optical-path unit, wherein the first-type polarized light transmitted from the second light splitting unit forms an enlarged image corresponding to a second focal length, and is converted into the second-type polarized light, after passing through the first optical-path unit; and a second optical-path unit, wherein the second-type polarized light reflected from the second light splitting unit is converted into the first-type polarized light after passing through the second optical-path unit.
