A multi-functional display is realized by utilizing optical processing based on spatial coding. The proposed display performs 2-D, 3-D, and peeping-prevention display. The display consists of two spatial light modulators of polarization-processing type. By use of optical encryption, the viewing zone is limited in three-dimensional space. By use of information sharing, stereoscopic images are provided. By use of modulation based on depth, depth-fused 3-D display is also realized. Without spatial modulation, conventional 2-D images are provided. Thus, the proposed display performs multi-functions without changing hardware configuration.
