ABSTRACT:
A display assembly in the form of a supporting shell that mounts the assembly in an upright display panel in a matrix configuration. A disk assembly is pivoted to each shell and includes a thin disk movable about a transverse horizontal axis. The disk is moved by magnetic forces between a reflective position exposing one disk surface to the front of the panel, a closed condition exposing its opposite surface to the front of the panel, and a backlighted condition which is intermediate the other two.
