Abstract: The disclosure discloses a near-to-eye display device, including: a first display screen, a first imaging lens, a second display screen, a second imaging lens and a waveguide. The first display screen provides a first image and the first image enters the waveguide through the first imaging lens. The second display screen provides a second image, the second image enters the waveguide through the second imaging lens. Imaging light rays from the first imaging lens and the second imaging lens can emit towards a light-emitting surface of the waveguide via a light taking part, and enter the human eyes.

Abstract: Disclosed is a near eye display apparatus, comprising a display screen and an imaging system. The imaging system comprises a biconvex lens, a transflective plane mirror and a transflective curved mirror. The biconvex lens is configured to magnify a display image of the display screen; the transflective plane mirror is configured to receive imaging light from the biconvex lens and reflect same to the transflective curved mirror; and the transflective curved mirror is configured to converge the imaging light and reflect same to the position(s) where human eyes are located.

Abstract: A near-to-eye display device, includes: a display screen configured to display different images in a first time division mode, a polarization converter at a light-emitting side of the display screen and configured to convert emitted light of the different images displayed by the display screen into first circularly polarized light rays and second circularly polarized light rays in a second time division mode. Here the first circularly polarized light rays and the second circularly polarized light rays are opposite in rotation direction. The device further includes a polarization lens at a side facing away from the display screen of the polarization converter, and a focusing lens at a side facing away from the display screen of the polarization converter. The polarization lens and the focusing lens are configured to focus the first circularly polarized light rays and the second circularly polarized light rays at positions of different focal lengths.
