Moving slit light field display

Abstract

This paper describes the design of a parallax based Moving Slit Light Field Display (MSLFD). A MSLFD shows multi parallax images, by using vertical slits in an opaque cylinder surrounding multiple static flat panel displays. It allows viewers looking towards the cylinder to see an image from any position. Currently, various forms of 3D display have been developed and flat panel 3D display has been in practical use for some time. But commercial 3D displays only show a stereogram. On the other hand, Light Field Displays have been developed for displaying the dense ray information of the space, [Endo et al. 2005; Jones et al. 2007]. These displays use a "Parallax barrier" to control the ray direction to the observer. It shows parallax images without the use of an eye glass. We describe a system to reduce the size of the display by using two dimensional Organic Light-Emitting Diodes (OLED) and a rounding slit. OLEDs can act as the dense light source array and it can be controlled line by line. This system proposes a method to synchronize the movement of OLED's line and movement of slits. It can show many images in multi orientation (Figure 1(a)). In this paper we explain the principal method of design and how to expand the resolution and views of a MSLFD. © ACM 2010.
