1. A display apparatus comprising:
an image generator comprising:
a light source;
a spatial light modulator configured to perform phase modulation on to-be-modulated image light to generate modulated first image light and modulated second image light;
an image panel is located between a light emitting surface of the light source and an incident surface of the spatial light modulator, wherein the image panel comprises a first display area and a second display area, and wherein the light source is configured to emit a light beam that passes through the first display area and the second display area to generate the to-be-modulated image light; and
an image displayer disposed on a light-emitting side of the image generator, wherein the image displayer comprising:
a first diffusing screen at a first spatial position and configured to receive a first projection of the modulated first image light; and
a second diffusing screen at a second spatial position and configured to receive a second projection of the modulated second image light.
