ABSTRACT:
An electroluminescent ("EL") lamp has EL material sandwiched between front and back conductive layers, which are disposed on a transparent substrate. The indiciae are formed from ink or other material deposited on the second surface of the front conductive layer, thereby completely burying the indicia within the EL lamp. The material may be transparent or colored, conductive or insulating, or made with an EL phosphor. The buried indicia provide sufficient contrast, when viewed with the EL lamp in an illuminated or non-illuminated state, to be seen. The present invention also describes a method for fabrication of such EL lamps.
