    摘要: An optical displaying system, a controlling method thereof, and a displaying device, which relates to the technical field of displaying. The optical displaying system includes a display screen (1); a first light splitting unit (2), wherein after a light ray emitted by the display screen (1) passes through the first light splitting unit (2), the light ray is converted into a first-type polarized light or a second-type polarized light; an imaging unit (3), wherein after a light ray exiting from the first light splitting unit (2) passes through the imaging unit (3), the light ray forms an enlarged image corresponding to a first focal length; a second light splitting unit (4); a first optical-path unit (5), wherein after the first-type polarized light transmitted out of the second light splitting unit (4) passes through the first optical-path unit (5), the first-type polarized light forms an enlarged image corresponding to a second focal length, is converted into the second-type polarized light; and a second optical-path unit (6), wherein after the second-type polarized light reflected out of the second light splitting unit (4) passes through the second optical-path unit (6), the second-type polarized light is converted into the first-type polarized light.

    摘要: The present disclosure provides an optical display system and method, and a display device. The optical display system includes: a display screen; a light split member configured to split light from the display screen into a first polarized light and a second polarized light with different polarization directions; a first optical waveguide configured to guide the first polarized light to a light exit side of the optical display system; and a second optical waveguide located at a light exit side of the first optical waveguide, spaced apart from the first optical waveguide, and configured to at least partially transmit the first polarized light and guide the second polarized light to the light exit side of the optical display system.

    摘要: An optical display system, a control method, and a display device, relates to the field of display technology. The optical display system comprises a display screen a first light splitting unit disposed at a display side of the display screen; a first imaging unit comprising a light splitting film disposed at a light-incident surface of the first imaging unit; a second light splitting unit disposed at a light emission side of the first imaging unit; a phase modulation unit disposed at least in a light path from the first imaging unit to the second light splitting unit; wherein, the first-type polarized light transmitted from the first light splitting unit is transmitted from a light emission side of the second light splitting unit, after being turned back multiple times between the first imaging unit and the second light splitting unit.
