Heads up display system and vehicle

Abstract

Provided are a heads up display system and a vehicle. An image generating device emits image light, which is reflected to a projection surface through a reflective assembly; a wavelength-selective reflective film is located on a reflective surface of the reflective assembly, realizing the selective reflection for different wavelength bands. The wavelength-selective reflective film is configured for reflecting at least part of the image light, ensuring that the image light is not affected by the arrangement of the wavelength-selective reflective film. When external interference light enters the heads up display system along a reverse optical path of the image light, the external interference light will first enter the wavelength-selective reflective film before entering the image generating device. The wavelength-selective reflective film only reflects interference light with the same wavelength band as the image light, thereby preventing the most of the interference light from entering the image generating device.
