Expanding the degree of freedom of observation on depth-direction by the triple-separated slanted parallax barrier in autostereoscopic 3D display

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