Abstract: A head-up display includes a picture generation unit and a first lens. The picture generation unit is configured to output a first light ray and a second light ray. The first light ray is used to output and display a first picture, and the second light ray is used to output and display a second picture. When the first lens is at the first position, the first light ray and the second light ray do not pass through the first lens. When the first lens is at the second position, the first light ray passes through the first lens. The head-up display can implement switching between a single image plane and a plurality of image planes.

Abstract: An information display device includes a spatial light modulator, configured to emit a holographic three-dimensional light field to a first grating, where the holographic three-dimensional light field corresponds to at least two focal planes, the first grating, configured to deflect the holographic three-dimensional light field emitted by the spatial light modulator, so that the holographic three-dimensional light field is propagated along a first direction and transmitted into an optical waveguide, the optical waveguide, configured to receive the holographic three-dimensional light field transmitted from the first grating, and propagate the holographic three-dimensional light field in the optical waveguide, and a second grating, configured to deflect the holographic three-dimensional light field that is propagated in the optical waveguide.
