摘要： A display system based on a four-dimensional light field, and a display method therefor. The display system includes: a light source module (11), a display panel (12), and a light conduction component (13), wherein the light source module (11) includes a plurality of light sources arranged in an array; and the display panel (12) is a reflective liquid crystal display panel, and the display panel (12) includes a plurality of pixel units arranged in an array. Light emitted by the light sources in the light source module (11) irradiates the pixel units in the display panel (12); and the pixel units in the display panel (12) transmit the received light to a target position by means of the light conduction component (13).

摘要： 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.

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.
