<p>A dotted projection imaging film for a glass curtain wall of a building. The projection imaging film comprises a light transmission base film layer, wherein a plurality of reflective base elements are in an array on the light transmission base film layer; the light transmission base film layer is covered with these reflective base elements; a separated region is provided between every two adjacent reflective base elements; and the regions of the light transmission base film layer corresponding to these separated regions are light transmission base elements. By means of the projection imaging film using the above-mentioned structure, these light transmission base elements can transmit light rays, thereby maintaining the normal illumination intensity in a building, and these reflective base elements can reflect projected light rays, thereby improving the projection quality of a glass curtain wall of a building.</p> |
