The invention provides laminated glass, a projection system and a vehicle. The interlayer of the laminated glass includes an in-coupling region and an out-coupling region. The projection light can enter the coupling-in area from the fourth surface, and the projection light can be reflected between the middle layer and the fourth surface in a reciprocating manner after being reflected by the coupling-in area, so that the projection light is propagated in the second glass plate; moreover, projection light propagating in the second glass plate can be emitted to the coupling-out area, and the projection light can penetrate through the fourth face after being reflected by the coupling-out area so as to be emitted out of the second glass plate. The refractive index of the polymer layer is smaller than that of the second glass plate, and the refractive index of air is smaller than that of the second glass plate, so that the second glass plate forms an optical waveguide structure, projection light can be transmitted in the second glass plate, and the coupling-in area and the coupling-out area are arranged in a matched mode. The projection light is totally reflected in the second glass plate, so that the ghosting phenomenon is reduced or even eliminated, and the display effect of the laminated glass is improved.

    本申请提供了夹层玻璃、投影系统及车辆。夹层玻璃的中间层包括耦入区域和耦出区域。投影光线能够自第四面射入至耦入区域,投影光线经耦入区域反射后能够在中间层与第四面之间往复反射,以使投影光线在第二玻璃板内传播;并且,在第二玻璃板内传播的投影光线射能够至耦出区域,投影光线经耦出区域反射后能够穿过第四面,以射出第二玻璃板。通过使聚合物层的折射率小于第二玻璃板的折射率,且空气的折射率小于第二玻璃板的折射率,使得第二玻璃板形成光波导结构,使得投影光线能够在第二玻璃板内传播,且配合设置耦入区域和耦出区域,使投影光线在第二玻璃板内发生全反射,从而减轻、甚至消除鬼影现象,提高了夹层玻璃的显示效果。
