In view of the demand of outdoor holographic projection, fully considering the requirements of outdoor use environment on light transmittance and projection effect, it is necessary to explore more suitable solutions to resist the impact of different outdoor environments on light transmittance and performance, and improve the durability and maintain the image clarity of outdoor holographic projection.
