ABSTRACT:
A full color TFEL display includes stacked panels emitting blue and a combination of red and green light. The panel nearest the viewer employs transparent electrodes on both sides and an insulator bridge structure for the scanning electrodes that alleviates the effect of pinhole defects. The panel farthest from the viewer employs transparent-top electrodes. Each row electrode on the scanning side includes an insulator bridge extending across the panel and then ITO pads extending laterally of the bridge onto the EL stack to form sub pixel points. A bus bar connects all the pixel pads in a row and provides the scanning voltage. The insulator bridge prevents the bus bars from shorting out and permits the pixel pads to fuse open in the event of a short circuit.
