Abstract
The present invention relates to a transparent projection screen having a Fresnel structure. The projection screen is provided with Fresnel structure units having a specific structure, such that incident light irradiated to each Fresnel structure unit can be corrected by a Fresnel microstructure at this position and is reflected in the direction of an observer within a certain visible range, thereby improving the display uniformity of the transparent projection screen, and also reducing the interference of external ambient light on the transparent projection screen, such that a projection system using the transparent projection screen has a good viewing effect.
