This chapter introduces the design principle of multi-view displays. A multiview display system comprises a flat-panel display, which shows the 2D information, and an optical device, which converts the 2D information into view images that produce a 3D effect. To begin, the basic concepts and terms of the multi-view display are introduced, which are essential to understanding system configuration. The detailed design parameters and the relationships of each part are then explained for practical implementation.
In a multi-view display, the image shown by the flat-panel display is called a base image array, which is the 2D information that contains directional images. The base image is composed of interwoven view images (also called directional images), i.e., the images shown only at specific directions. Each base image is assigned to a corresponding lenticule (a cylindrical lens in a lenticular display) or vertical slit (in a parallax-barrier display). Another important concept of multi-view displays is a viewing point (or viewpoint): a position from which the view images are optimally observed. Because the pixel of display has a finite size, the viewing point also has a certain area that provides the same view images. This region is usually known as the viewing zone, viewing region, or viewing window. These terms sometimes refer to the entire possible viewing points of the system rather than a single viewing point.However, this text uses those terms to indicate a viewing point for a specific view image.
