- The time and spatial multiplexing which are frequently employed in holographic displays based on display chips of the same characteristics, to increase reconstructed image size and resolution can hardly improve the viewing condition such as viewing zone and viewing angles more than what a chip can offer. This is demonstrated optically and experimentally with the holographic displays built with an array of 2×10 DMDs which is formed both by time and spatial multiplexing. It is considered that the viewing condition of the spatial multiplexing is somewhat worse than that obtained by time multiplexing because the reconstructed image size of each chip cannot be smaller than the hologram size. Furthermore, the spatially multiplexed image can be noisier than that obtained from time multiplexing but it shows better light efficiency. Added on this, it does not introduce a distortion in the image as in the time multiplexing.
