Multi-view autostereoscopic display — A display with more than two viewing zones. The viewing zone forming optics of such a display includes parallax barrier or lenticular lens array, etc. (as shown in figure 5). The viewer should stay at designated eye positions to watch this kind of display. The viewing distance is limited in a certain range. The more the viewing zones are, the bigger the range is. Although the lateral position is not limited as strictly as a 2-view 3D display, it is still restricted. As the number of viewing zones increases, the transverse freedom increases in size.
