The invention provides head-up display glass and a head-up display system. The head-up display glass comprises outer-layer glass, inner-layer glass, a middle layer and a reflecting film layer, the middle layer is arranged between the second surface of the outer-layer glass and the third surface of the inner-layer glass, the reflecting film layer is arranged on the fourth surface of the inner-layer glass, and the reflecting film layer can reflect P polarized light; the reflective film layer comprises at least one low-radiation layer and at least one laminated structure which are laminated, each laminated structure comprises a high-refractive-index layer and a low-refractive-index layer which are laminated in sequence, the high-refractive-index layer in each laminated structure is closer to the fourth surface than the low-refractive-index layer, the refractive index of the high-refractive-index layer is greater than or equal to 1.8, and the refractive index of the low-refractive-index layer is greater than or equal to 1.8. The refractive index of the low refractive index layer is less than 1.8. According to the invention, multiple performances of head-up display (HUD), heat insulation and low radiation can be considered, so that a driver or a passenger can more clearly observe a clear head-up display image without double images.
本申请提供一种抬头显示玻璃和抬头显示系统。抬头显示玻璃包括外层玻璃、内层玻璃、中间层和反射膜层,中间层设于外层玻璃的第二表面和内层玻璃的第三表面之间,反射膜层设置在内层玻璃的第四表面上,反射膜层能够反射P偏振光;反射膜层包括层叠设置的至少一个低辐射层和至少一个叠层结构,每个叠层结构包括依次层叠的高折射率层和低折射率层,每个叠层结构中的高折射率层比低折射率层更靠近第四表面,高折射率层的折射率大于或等于1.8,低折射率层的折射率小于1.8。本申请能够兼顾抬头显示(HUD)、隔热和低辐射的多重性能,使驾驶员或乘客可以更清楚地观察到清晰无重影的抬头显示图像。
