    • A projection system is provided. The projection system comprises a projector for producing a polarized light for projecting an image and a projection screen on which the image projected by the projector is visualized. The polarization plane of the polarized light and the polarization plane of the polarizing means are parallel. The polarizing means comprises a film formed by rodlike supramolecules including at least one polycyclic organic compound with conjugated π-systems, whereby the 40% viewing angle transmittance iso-line of the polarizing means of the screen has an aspect ratio of not less than 2.
    • 提供投影系统。 投影系统包括用于产生用于投影图像的偏振光的投影仪和由投影仪投射的图像可视化的投影屏幕。 偏振光的偏振面和偏振光的偏振面平行。 偏振装置包括由包括至少一种具有共轭π系的多环有机化合物的棒状超分子形成的膜,由此屏幕的偏振装置的40%视角透射率等值线具有不小于2的纵横比。
