Abstract
Multilayer displays are constructed by stacking multiple liquid crystal panels along with a pair of polarizers and a light source. Previous theoretical analyses have shown that such a display could exhibit the light field of a 3D scene if the panels in the display are properly controlled. In this study, we present an implementation of a monochromatic multilayer display using IPS-LCD panels, and report that a reasonable approximation of the light field is actually observed from the display. A major obstacle to constructing a multilayer display is the complexity of optical properties of LCD panels. Since an accurate analytic representation of panels' behavior is difficult to obtain, we have developed an approximate model specific to IPS-LCD cells, using which our implementation is built. We then evaluate the quality of the light field observed from the prototype implementation by examining the images photographed at several camera positions. The results show geometrically correct views are observable from the display within the viewing angle of 30 degrees.
