P‐99: Glasses‐Free 3D Display for Cinema Applications Employing a MiniLED Display and Radial Parallax Barrier

We describe a prototype glasses‐free 3D display suitable for large audiences such as cinema or out‐of‐home advertising. This is based on designs originally developed in 1940’s that used a radial parallax barrier to provide an optimum viewing plane (OVP) that passes through the eyes of seated viewers in the auditorium; this is an improvement over a conventional parallel barrier display where the OVP is parallel to the screen. The original principle is updated by replacing a projector behind the viewers with a miniLED display panel located behind the barrier.
