Abstract :
The moirés appearing in the contact-type 3 dimensional displays are chirped by the thickness of the viewing zone forming optics (VZFO) in the displays. Due to the thickness, the patterns of the display panels for the displays are refracted on to the pattern plane of VZFO to superpose with the pattern on the plane. The moirés formed this way can have chirped fringe patterns, and change numbers and phases of their fringes according to the changes in viewer´s viewing positions and viewing angles at a given viewing distance.
