The invention belongs to the technical field of head-up display, and particularly discloses head-up display glass and a head-up display system. The head-up display glass comprises a glass plate and a reflective film layer, the reflective film layer is arranged on a first surface of the glass plate to form a film-coated surface, and the other surface of the glass plate is a glass surface. The reflecting film layer comprises a first high-refractive-index layer, a second low-refractive-index layer, a third high-refractive-index layer and a fourth low-refractive-index layer which are sequentially stacked outwards. The sum of the thicknesses of the second low refractive index layer and the fourth low refractive index layer is greater than the sum of the thicknesses of the first high refractive index layer and the third high refractive index layer. The single-sided reflectivity of the coated surface to P polarized light incident at an incident angle of 57.5 degrees is greater than or equal to 14.7%, and the single-sided reflectivity of the coated surface to S polarized light incident at an incident angle of 57.5 degrees is greater than or equal to 19%. The head-up display system comprises a projection unit and the head-up display glass, and the ratio of P polarized light to S polarized light in projection light is 95: 5. The device can eliminate ghosting, is simple in structure, and is suitable for mass production.

    本发明属于抬头显示技术领域,具体公开了一种抬头显示玻璃和抬头显示系统。抬头显示玻璃包括玻璃板和反射膜层,反射膜层设在玻璃板的第一表面上形成镀膜面,玻璃板的另一表面为玻璃面。反射膜层包括向外依次层叠的第一高折射率层、第二低折射率层、第三高折射率层和第四低折射率层。第二低折射率层和第四低折射率层的厚度和大于第一高折射率层和第三高折射率层的厚度和。镀膜面对以57.5°入射角入射的P偏振光的单面反射率大于或等于14.7%,镀膜面对以57.5°入射角入射的S偏振光的单面反射率大于或等于19%。抬头显示系统包括投影单元和上述抬头显示玻璃,投影光线中的P偏振光:S偏振光=95:5。本发明能够消除重影并且结构简单,适于大量生产。
