The invention concerns a vehicle glazing and display system (1) comprising a vehicle compound glazing unit (10; 10'; 10'') comprising a layer or surface (12a; 12b; 14) switchable between active first state and a second state, which, in the first state, diffusely reflects incident light directed to the glazing unit from a first side of the vehicle compound glazing unit (10; 10'; 10'') to a second side of the vehicle compound glazing unit (10; 10'; 10'') and having a maximum gain in the range of 0.03 to 0.8, preferably between 0.3 and 0.6 and an intrinsic viewing angle alpha for a real image element generated within the glazing plane of more than 60 degrees, in a first direction and of more than 30 degrees, in a second direction, perpendicular to the first direction in a reflection geometry, and which in the second state is transparent, a projector (4) for projecting an image to the vehicle glazing unit to generate a real image in the plane of the glazing unit and wherein the vehicle compound glazing unit (10; 10'; 10'') is a side window or partition window (3) and a projector control unit for controlling the projector and the switching of the layer or surface.
本发明涉及一种车辆玻璃窗和显示系统(1),其包括:车辆复合玻璃窗单元(10;10’;10’’),其包括能够在有源的第一状态和第二状态之间切换的层或表面(12a;12b;14),该层或表面在第一状态下将被引导到玻璃窗单元的入射光从车辆复合玻璃窗单元(10;10’;10’’)的第一侧漫反射到车辆复合玻璃窗单元(10;10’;10’’)的第二侧,并具有在0.03至0.8的范围内、优选地在0.3和0.6之间的最大增益以及用于在玻璃窗平面内生成的实像元素的固有视角α,该固有视角α在反射几何形状中沿第一方向大于60°并且沿垂直于第一方向的第二方向大于30°,并且该层或表面在第二状态下是透明的;投影仪(4),其用于将图像投影到车辆玻璃窗单元以在玻璃窗单元的平面中生成实像,并且其中,车辆复合玻璃窗单元(10;10’;10’’)是侧车窗或分隔车窗(3);以及投影仪控制单元,其用于切换投影仪以及对该层或表面的切换。
