This paper proposes two moiré reduction methods for coarse integral volumetric displays composed of multilayer display panels. The quality of the image presented by the conventional multilayer integral imaging stays relatively low because of the moiré pattern, which appears due to the layering structure of display panels with limited pixel aperture. The authors propose two methods to solve this problem. The first method is to add another layer of convex lens array with short focal length on the front side of the layered display panels. The second method is to enlarge the pixel pitch of the back-layer panel while fixing that of the front-layer panel.
