2‐D/3‐D switchable displays

— In this paper, the design of a lenticular-based 2-D/3-D display for mobile applications is described. This display combines look-around capability with good 3-D resolution. In order to allow high-resolution datagraphic applications, a concept based on actively switched lenses has been developed. A very noticeable problem for such displays is the occurrence of dark bands. Despite slanting the lenticular and defocusing the lens, banding becomes unacceptable when the display is viewed from an angle. As a solution, fractional viewing systems to reduce the banding intensity by almost two orders of magnitude is introduced. The resulting 3-D display can be viewed from any horizontal direction without banding.
