The invention relates to a transflective film, a head-up display system and a vehicle, the reflectivity of the transflective film to first polarized light is greater than the reflectivity of the transflective film to second polarized light, the first polarized light is one of P polarized light and S polarized light, and the second polarized light is the other of the P polarized light and the S polarized light; the transflective film comprises a dielectric layer and a metal layer, wherein the dielectric layer and the metal layer are laminated; the dielectric layers are located on the two sides of the metal layer in the lamination direction; the at least one dielectric layer comprises a first sub-dielectric layer and a second sub-dielectric layer which are alternately laminated along the lamination direction, and the refractive index of the first sub-dielectric layer is greater than that of the second sub-dielectric layer. The transflective film has higher reflectivity for the first polarized light and lower reflectivity for the second polarized light, and is applied to the head-up display system, and the reflectivity of the image light is improved by adopting the corresponding transflective film according to the polarized light type (P polarized light or S polarized light) of the image light, so that the display brightness and the display effect of the image are improved.
本公开涉及透反膜、抬头显示系统及交通工具,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,第一偏振光为P偏振光和S偏振光中的一种,第二偏振光为P偏振光和S偏振光中另一种;该透反膜包括:介质层和金属层,介质层与金属层叠层设置;沿叠层方向,介质层位于金属层的两侧;至少一介质层包括沿叠层方向交替层叠的第一子介质层和第二子介质层,第一子介质层的折射率大于第二子介质层的折射率。利用透反膜对第一偏振光具有较高的反射率,对第二偏振光具有较低的反射率,将其应用于抬头显示系统,根据图像光线的偏振光类型(P偏振光或S偏振光),采用对应的透反膜提高图像光线的反射率,从而提高图像的显示亮度和显示效果。
