Abstract
A three-dimensional (3D) display apparatus and method are provided. The 3D display apparatus may include a display screen configured to display each of a plurality of sub-images included in a single frame of a 3D image using a time-division multiplexing (TDM), a polarizer configured to polarize each of the displayed sub-images by changing a polarization direction using the TDM, in synchronization with the display screen, and microlens arrays arranged in a plurality of layers and configured to sequentially refract the polarized sub-images, respectively.
