The invention discloses a vehicle-mounted head-up display film and a vehicle-mounted head-up display system.The vehicle-mounted head-up display film is attached to the inner surface of an automobile front windshield and used for reflecting S polarized light, and the vehicle-mounted head-up display film comprises a light deflection layer and an S polarized light reflecting layer which are arranged in a stacked mode; the surface, deviating from the S polarized light reflecting layer, of the light deflection layer is connected with the inner surface of the automobile front windshield, and the light deflection layer is used for converting S polarized light into P polarized light; in the wave band of 380 nm to 780 nm, the average reflectivity of the S polarized light reflecting layer to S polarized light with the incident angle of 30 degrees to 60 degrees is 24.09% to 37.9%. The vehicle-mounted head-up display film can effectively eliminate ghosts on the inner and outer surfaces of an automobile front windshield, improve the definition of images and enhance the display contrast.

    本发明公开了一种车载抬头显示膜以及车载抬头显示系统,所述车载抬头显示膜贴合在汽车前挡风玻璃内表面用于反射S偏振光,所述车载抬头显示膜包括层叠设置的光偏转层以及S偏振光反射层;所述光偏转层上背离S偏振光反射层的面与汽车前挡风玻璃内表面相连接,所述光偏转层用于将S偏振光转换为P偏振光;在380nm‑780nm波段内,所述S偏振光反射层对入射角度为30°‑60°的S偏振光的平均反射率为24.09‑37.9%。本发明的车载抬头显示膜能够有效消除汽车前挡风玻璃内外表面的重影,提高图像的清晰度,增强显示的对比度。
