Abstract: A display apparatus includes an image generator including a spatial light modulator that is configured to perform phase modulation on to-be-modulated image light to generate modulated first image light and modulated second image light, and an image display module that is disposed on a light emitting side of the image generator. The image display module includes a first diffusing screen and a second diffusing screen. The first image light is projected on the first diffusing screen and the second image light is projected on the second diffusing screen. A spatial position of the first diffusing screen is different from a spatial position of the second diffusing screen.

Abstract: An optical system. A light source component generates a light beam. A light adjustment component adjusts a ratio of the S-polarized light and a ratio of the P-polarized light in the light beam. A first polarization beamsplitter mirror component splits a light beam adjusted by the light adjustment component into a first light beam and a second light beam, where the first light beam is a light beam of the S-polarized light, and the second light beam is a light beam of the P-polarized light. The first lens component projects the first light beam or a modulated first light beam to a first region. The second lens component projects the second light beam or a modulated second light beam to a second region.
