Abstract

Apparatus and systems, as well as methods and articles, may operate to display image information from one side of a light-emitting material layer disposed between a pair of non-opaque electrodes. The image information may be displayed through a transparent substrate, perhaps adjacent a conductive silicon layer, adjacent one of the electrodes. The image information may also be displayed substantially simultaneously from the other side of the light emitting material layer.
