Method and apparatus for fabricating polymer-based electroluminescent displays

A method for fabricating an electroluminescent display, said method comprising:

• providing a substrate comprising a flexible base layer having a conducting surface on one side thereof, said base layer being at least 1000 times less permeable to oxygen and water than a PET film of the same thickness as said base layer, said substrate further comprising a plurality of wells defined by a barrier layer, each of said wells having an electrode layer connected electrically with said conducting surface;
• moving a first dispenser relative to said substrate so as to quantitatively deposit a first electroluminescent material on said substrate, different amounts of said first electroluminescent material being deposited at different locations on said substrate in response to signals defining an illumination pattern to be generated by said display;
• and
• depositing a conducting material on said first electroluminescent material.
