Abstract
A flexible sheet which includes a substrate having at least one visually discernable surface and at least one electroluminescent lamp assembly positioned proximate to the surface and controlled by a suitable power source as well as means for isolating at least one electroluminescent lamp assembly from deleterious interaction with environment external to the flexible sheet. The flexible sheet can be employed in various applications including bound books, functional cards, locational orientation devices as well as in mechanisms for selectively indicating ingress or egress from architectural structures and other safety indicators. At least one component of the flexible sheet with the electroluminescent lamp assembly can be produced by drop ejection.
