The invention discloses a transparent reflecting screen for an information display system with an image information display device, which is characterized in that an image displayed by the image information display device is overlapped with a real scene opposite to a viewer in the form of an amplified virtual image, so that the viewer can see the image; a special diaphragm is attached to an image light incident surface of the optical imaging device, the special diaphragm is formed by jointing or attaching a phase difference plate and a transparent plate, optical filters with different transmissivity to S polarized light and P polarized light are designed on one surface or two surfaces of the transparent plate, and the refractive indexes of adhesives or binders and constituent materials of the phase difference plate, the transparent plate and the transparent reflecting screen are almost equal. According to the invention, ghosting caused by the ghosting can be obviously reduced, and high-resolution image information display is realized. According to the invention, the divergence angle of the image light is reduced to the sharp angle, so that the image light is consistent with the specific polarization, the image light is effectively and efficiently transmitted to a viewer, and the utilization efficiency of the light is greatly improved.
本发明公开了一种具有图像信息显示装置的信息显示系统所用的透明反射屏,是将图像信息显示装置显示的图像以放大的虚像与观看者对面的实景重叠,使观看者看到;其图像光入射面贴有特殊膜片,特殊膜片由相位差板、透明板接合或贴合而成,透明板的一面或两面设计有对S偏振光和P偏振光透过率不同的光学滤光片,相位差板、透明板和透明反射屏的接合剂或粘结剂和构成材料的折射率几乎相等。本发明可以显著减少由此产生的重影,实现高分辨率的图像信息显示。通过减小图像光的发散角为鋭角,使其与特定的偏振一致,有效地将图像光高效地传递给观看者,从而大幅提高光的利用效率。
