    Abstract: A display device includes: a first coupling-in module configured to couple first image light into a light guide assembly at a preset first incident angle, thereby enabling the first image light to propagate in the light guide assembly by total reflection and to be incident in a coupling-out light-splitting module; a second coupling-in module configured to couple second image light into the light guide assembly at a preset second incident angle, thereby enabling the second image light to propagate in the light guide assembly and to be incident in the coupling-out light-splitting module; a coupling-out light-splitting module configured to, couple the first and second image light out from the light guide assembly to enter a first position area and a second position area of the human eye, respectively. The first and second image light are different light field information of an identical image; and are both collimated light.

    Abstract: A display apparatus including: a display screen including multiple light-emitting points and a first side, wherein light generated by the light-emitting points emits from the first side; and a microlens array provided on the first side of the display screen, the microlens array includes multiple microlenses arranged in an array, an orthographic projection of the microlens array on the display screen covers the display screen, and the display screen is provided on a focal surface of the microlens array. The focal lengths of the multiple microlenses increase sequentially from the center of the microlens array to the edge of the microlens array, so that a beam width of the light that is emitted from each light-emitting point of the display, transmits through the microlens array and is incident into a pupil of a human eye is less than a preset threshold.
