A transparent projection screen, a projection system, glass and a vehicle relate to the technical field of projection. The transparent projection screen comprises a first film layer, a reflecting film layer and a second film layer, the first film layer, the reflecting film layer and the second film layer are arranged in a stacked mode, the first film layer comprises a micro-lens array structure, the reflecting film layer is used for reflecting light emitted by the projection equipment, and the absolute value of the difference value of the refractive indexes of the first film layer and the second film layer is smaller than or equal to 0.02. At least part of light emitted by the projection equipment can be reflected under the action of the reflecting film layer, the reflected light is scattered under the action of the micro-lens array structure and is incident to human eyes, so that the projection effect is achieved, light on the opposite side of the projection equipment can penetrate through the transparent projection screen to be incident to the human eyes, and therefore the projection effect is improved. And the overall permeability of the transparent projection screen is not influenced.

    一种透明投影屏、投影系统、玻璃及车辆,涉及投影技术领域。透明投影屏包括第一膜层和、反射膜层和第二膜层,第一膜层、反射膜层和第二膜层层叠设置,第一膜层包括微透镜阵列结构,反射膜层用于反射投影设备发出的光,第一膜层和第二膜层的折射率差值绝对值小于或等于0.02。投影设备发出的光可以在反射膜层的作用下,至少部分发生反射,反射光在微透镜阵列结构的作用下发生散射,并入射至人眼,从而达到投影的效果,在投影设备对侧的光可以透过透明投影屏入射至人眼,因此,不会影响透明投影屏的整体通透性。
