Abstract
An electroluminescent display includes a plurality of generally parallel outer electrodes and a plurality of generally parallel inner electrodes perpendicular to the outer electrodes. A plurality of generally parallel reflective surfaces are formed parallel to the outer electrodes or the inner electrodes to selectively provide a mirrored appearance when the electroluminescent display is not activated. A variable transmissive device, such as an electrochromic dimmer, is positioned in front of the ELD to selectively dim the light emitted from the ELD.
