Abstract
Electroluminescent (EL) displays, media, and members, and methods associated therewith. One such display includes an EL material, conductor layers, and a reflective image formed by a pattern of imaging substance applied adjacent at least one of the conductor layers. The EL material is between at least two of the conductor layers, and at least one of the conductor layers is applied adjacent the EL material in a pattern to form a conductive image. Upon application of an operational potential to the at least two of the conductor layers having the EL material therebetween, the display can be illuminated in an area corresponding to the conductive image.
