Fractional viewing systems to reduce banding in lenticular based 3D displays

In this paper we describe the design of a 4 inch 5 view lenticular based 2D/3D display for mobile applications A very noticeable such displays is the occurrence of dark bonds. We will show that, despite slanting the lenticular and defocusing the lens, banding becomes unacceptable when the display is viewed from an angle. As a solution, we introduce fractional viewing systems to reduce the banding intensity by almost two orders of magnitude. The resulting 3D display can be viewed from any direction without banding.
