The invention discloses a holographic multiplexing car window system and a holographic multiplexing method.The system comprises an image projection module, a holographic optical element waveguide combiner and a solar cell module, the holographic optical element waveguide combiner comprises an optical waveguide, a light collecting holographic optical element, a coupling-out optical element and an imaging holographic optical element, the light-collecting holographic optical element and the imaging holographic optical element are attached to the optical waveguide, the light-collecting holographic optical element covers the whole optical waveguide, the imaging holographic optical element covers partial area of the optical waveguide, and the light-collecting holographic optical element and the imaging holographic optical element adopt a single-layer multiplexing mode or a multi-layer stacking multiplexing mode. According to the system and the method, external light energy can be utilized, while the influence of external strong light on driving is reduced, the light energy of the external light coupled out by the out-coupling optical element is converted into electric energy to supply power to the image projection module and the electric equipment in the vehicle, the influence of stray light formed by external light diffraction on the display system can be weakened, and the display effect is better.
