A see‐through 2D/3D compatible display based on integral imaging is proposed. It consists of a lens‐array holographic optical element (LAHOE) film, a polymer dispersed liquid crystal (PDLC) film and two projectors. The see‐through projection screen is composed of the LAHOE film and the PDLC film. The PDLC film is tightly behind the LAHOE film. With applied voltage, the projection screen works in the transparent display mode. 3D image for Bragg matched image can be presented, and 2D image can also be presented.
