Abstract: A display system is provided. The display system includes a windshield, a picture generation unit (PGU), and an optical element, where the windshield includes a first windshield surface and a second windshield surface. The PGU projects a light beam corresponding to a picture generated by the PGU to the optical element. The optical element directs the light beam to the first windshield surface. The first windshield surface refracts the light beam to the second windshield surface, and reflects the light beam to a human eye for receiving. The first windshield surface refracts a light beam reflected from the second windshield surface to the human eye for receiving. After reflection by the first windshield surface, the light beam forms a first virtual image with the picture. After reflection by the second windshield surface and refraction by the first windshield surface, the light beam forms a second virtual image with the picture.

Abstract: One example power equalizer includes an input/output assembly, a multiplexer/demultiplexer, a pre-attenuation component, and a light beam modulator. The multiplexer/demultiplexer demultiplexes a first light beam into a plurality of first sub-wavelength light beams including a particular sub-wavelength light beam, and propagates the plurality of first sub-wavelength light beams to the pre-attenuation component. The pre-attenuation component makes the particular sub-wavelength light beam incident onto the light beam modulator at a preset angle. The light beam modulator performs angular deflection on the plurality of first sub-wavelength light beams to obtain a plurality of second sub-wavelength light beams. The pre-attenuation component then propagates the plurality of second sub-wavelength light beams to the multiplexer/demultiplexer. The multiplexer/demultiplexer multiplexes the plurality of second sub-wavelength light beams into a second light beam.
