摘要： 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.
