The invention relates to the technical field of head-up displays, in particular to a reflecting part, a head-up display system and a vehicle. The reflecting part comprises a substrate, a transflective film and a first antireflection film, the reflectivity of the transflective film to first polarized light is larger than that of the transflective film to second polarized light, the first antireflection film is located on one side of the substrate, the transflective film is located in the substrate, or the transflective film is located on the other side of the substrate, and the first antireflection film is located in the substrate. Or the transflective film is located between the first antireflection film and the substrate. By arranging the transflective film, when the light is reflected, the reflectivity for the first polarized light is greater than the reflectivity for the second polarized light, so that when the image light of the image source is the first polarized light, the reflectivity for the first polarized light can be improved, and the display effect and the display brightness of the image are improved. And by arranging the first antireflection film, the light transmission amount of the reflecting piece is increased, and the imaging definition is further improved.

    本公开涉及抬头显示器技术领域,尤其涉及一种反射件、抬头显示系统和交通工具。反射件包括基板、透反膜和第一增透膜,所述透反膜对第一偏振光的反射率大于对第二偏振光的反射率,所述第一增透膜位于所述基板的一侧,所述透反膜位于所述基板的内部,或者所述透反膜位于所述基板的另一侧,或者所述透反膜位于所述第一增透膜与所述基板之间。通过设置透反膜,在对光线进行反射时,对第一偏振光的反射率大于对第二偏振光的反射率,这样在像源图像光线为第一偏振光时,可以提高对第一偏振光的反射率,从而提高图像的显示效果和显示亮度。通过设置第一增透膜,增加了反射件的透光量,进一步提高了成像的清晰度。
