ABSTRACT:
The present invention (1) includes a multi-focal plane display with two or more at least partially overlapping screens (2, 3) with a first order optical retarder (5) interposed therebetween. The invention removes the undersirable presence of colored interference fringes while also providing a means of addressing the polarization incompatibility between adjacent LCD display screens (2, 3).
