- An autostereoscopic multi-view 3D display system has the narrower degrees of freedom in the observational
directions, such as the horizontal and perpendicular directions to the display plane, than the glasses-on type of 3D
display. In this paper, we propose an innovative method to expand the width of the viewing zone formed in the
depth direction while maintaining the number of views in the horizontal direction by using a triple segmented-slanted parallax barrier (TS-SPB) in the glasses-off type of 3D display. The validity of the proposal
was verified by an optical simulation based on an environment similar to an actual case. The maximum number
of views that can be displayed in the horizontal direction is 2n, and the width of the viewing zone with depth
increased up to a factor of 3.36 compared to the existing one-layered parallax barrier system.
