Analysis of the Dependence of the Viewing Zones on the Display Radius in Autostereoscopic 2 View Displays of Horizontally Concave Surface

In autostereoscopic display, ray trajectories through the optic element such as the parallax barrier or the lenticular lens are affected by the radius of horizontally concave display. Using the intersection of the calculated trajectories of the rays coming from the various positions of the autostereoscopic 2 view display of the curved surface, the viewing zones and area of the incomplete separation of the images for the left and right eyes were investigated. The area of incomplete separation of the images for the left and right eyes related to the triangular areas defined by three chief rays coming from the left edge, center, and the right edge. These triangular areas for the curved surface was smaller than those for the flat surface and showed the tendency of the decrease as the ratio of the radius of the curved and the designed viewing distance approached 1/2.
