1. A transparent active-matrix display, comprising:
- a) a transparent substrate;
b) a multiplicity of active pixel elements arranged in an array on the substrate, each of the pixel elements being adapted to be set independently to two or more states, each of the pixel elements being transparent in at least one of its two or more states; and
c) transparent electrical connections to each pixel element whereby the transparent display is adapted to be controlled.

Abstract
A transparent active-matrix display based on a substrate has a multiplicity of transparent active pixel elements arranged in an array and transparent electrical connections to each pixel, whereby each of the pixel elements is adapted to be set independently to two or more states. In some embodiments, the substrate may also be transparent.
