Abstract

A display system for presenting one or more planes of display information. The display system may include two or more display modules positioned in a spaced relationship in a stacked formation substantially along a Z-axis perpendicular to a display face of a display module. Each display module may be selectively activated to display a visual image or deactivated to a quiescent state. Further, when a display module is activated to display the viewed image, the viewed image can be viewed through a prior display module which is deactivated to a quiescent state.

13. The method of claim 11, further comprising the step of activating a single display module to display the image at a point in time, wherein when the second display is activated to display the image the first display module is visually transparent in the quiescent state.

14. The method of claim 11, further comprising the step of activating more than one display module to display the image.

15. The method of claim 11, further providing a static opaque layer positioned behind the second display module distal from the first display module in the Z-axis, wherein the second display module is visually transparent.

16. The method of claim 11, further providing a dynamic opaque layer positioned behind the second display module distal from the first display module in the Z-axis, wherein the dynamic opaque layer can be activated to an opaque visual state and deactivated to a transparent visual state.
