Holographic projection film has unique transparency, which allows the audience to see the scenery behind it through the projection film while maintaining clear imaging. The picture quality 100% is clear and bright, and it is extremely thin, with no space limitation. This magical effect benefits from the practical application of comprehensive diffraction pattern technology published for the first time in the international market. For the first time in the world, an epoch-making patented projection film that can directly watch images from both sides and multiple angles at the same time, regardless of whether the light source is sufficient or not, has been realized. Excellent imaging effect: crystal clear picture, unique high-definition transparent imaging, forming crystal clear vision, grasping the curiosity and attention of the audience at the first time, spreading visual information with high quality, and not hindering the display of on-site exhibits. Simple and slim materials convey that the design is meaningful, simple and slim, and contains infinite connotation.
