Abstract:
Disclosed are a near-eye display apparatus. The near-eye display apparatus comprises: a display screen; a polarization converter; an imaging lens group; a semi-transparent and semi-reflective layer arranged between the polarization converter and the first lens; a reflective polarized layer arranged on the side, facing away from the polarization converter, of the semi-transparent and semi-reflective layer, the polarization direction of the first linearly polarized light is vertical to the polarization direction of the second linearly polarized light; and a liquid crystal lens arranged between the semi-transparent and semi-reflective layer and the reflective polarized layer. When the liquid crystal lens is switched between the first phase retardation amount and the second phase retardation amount, the light path of light in the near-eye display apparatus changes, so that the near-eye display apparatus can image at two focal lengths.
