The invention relates to the technical field of image information display, in particular to an information display system based on an image information device and a transparent reflecting screen, which is characterized in that image information displayed on the image information device is overlapped with a real scene opposite to a viewer through the transparent reflecting screen, so that the viewer can see the image information; a special film is adhered to an image light incident surface of the transparent reflecting screen, the special film is formed by laminating a phase difference plate and a transparent plate, optical filters with different transmittance to S light and P light are adhered to one or two surfaces of the transparent plate, and the refractive indexes of adhesives for adhering the phase difference plate and the transparent plate to the transparent reflecting screen are almost equal. Compared with the prior art, the technology of high brightness, low power consumption and no ghosting can be provided, and proper images can be displayed to viewers.
本发明涉及图像信息显示技术领域,具体涉及一种基于图像信息装置和透明反射屏的信息显示系统,具体是将显示在图像信息装置上的图像信息通过透明反射屏,和观看者对面的实景重叠,使观看者能够看到;透明反射屏的图像光入射面上粘合有特殊膜,该特殊膜由相位差板和透明板贴合组成,在前述透明板的一面或两面上贴有对S光和P光的透过率不同的光学滤光片,用于将位相差板和透明板粘合到透明反射屏上的粘合剂的折射率几乎相等。与现有技术相比,本发明能够提供高亮度、低功耗且无重影,实现向观看者显示适宜图像的技术。
