Abstract
A hard plastic card display device including a hard plastic card having a major surface and a driver circuit. A display, including a plurality of inverted organic light emitting diodes, is formed on the major surface and coupled to the driver circuit.
Claims6
An organic light emitting diode device comprising:
- a plastic substrate having a major surface including a well;
- and
- an inverted organic light emitting diode formed in the well on the major surface of the plastic substrate and inverted so as to emit light away from the plastic substrate, the inverted organic light emitting diode including a moisture and oxygen barrier layer formed in the well on the major surface, a plurality of interconnects formed on the barrier layer, a metal alloy formed on the plurality of interconnects, an organic electroluminence media layer formed on the metal alloy, and a transparent conductor formed on the organic electroluminence media layer.
A plastic card display device comprising:
- a plastic card selected from one of a smart card, a credit card, and an identification card, including a major surface defining a well and a driver circuit;
- a display formed on the major surface and coupled to the driver circuit, the display including a plurality of inverted organic light emitting diodes positioned in the well and encapsulated and sealed by a transparent dielectric media, the inverted organic light emitting diodes being inverted so as to emit light away from the plastic substrate, each inverted organic light emitting diode including a moisture and oxygen barrier layer formed on the major surface, a plurality of interconnects formed on the barrier layer and coupled to the driver circuit, a metal alloy formed on the plurality of interconnects, an organic electroluminence media layer formed on the metal alloy, and a transparent conductor formed on the organic electroluminence media layer.
