The invention provides an information display system which enables video information displayed on a video display device to be superimposed on an external landscape via a windshield and a superimposition mirror so that the video information can be observed by a monitor, and comprises a light source device which supplies light in a specific polarization direction to the video display device at a narrow divergence angle. A monitoring angle at which a monitor observes an image is fixed and the position or angle of the image display device is changed with respect to the windshield, whereby it is possible to change the reflection position of the image information, the display distance of a virtual image observed by the monitor, and the size of the image according to the installation state in the vehicle.
本发明提供一种信息显示系统,使显示在影像显示装置上的影像信息经由挡风玻璃和叠像镜与外界的景观叠加从而能够由监视者观察,其包括以窄角的发散角对影像显示装置供给特定偏振方向的光的光源装置,使监视者观察影像的监视角度固定且相对于所述挡风玻璃改变影像显示装置的位置或角度进行配置,由此通过车内的设置状态能够实现改变影像信息的反射位置、变更监视者观察的虚像的显示距离和影像的大小。
