Abstract
A thin film electroluminescent display module sealed against moisture with driver chip and optional lens is disclosed. The module is formed on a transparent substrate upon which a sequence of patterned thin layers is deposited and a patterned sealing layer and driver circuit(s) are applied. In one aspect the tile element achieves over 100 fL brightness in a 5.times.7 format with circular pixels. Expansion to a 16.times.16 format is also disclosed and a novel addressing geometry suitable for tiled displays is presented. The application of a unique insulator layer allows flexible interconnections with conductor crossovers to address pixel arrays in formats offer than X-Y matrix addressing. The absence of edge connections and a bulky edge seal permits production of a tiled display in which module-to-module spacing is not limited by connectors or seals. Multiple electroluminescent display modules may be tiled together edge-to-edge to form a large display panel.
