Solution-Coating Technology for AMOLED Displays

摘要

DuPont Displays has developed a full set of high-performance materials and solution-processing technology to address the high cost of manufacturing AMOLEDs. We optimized our coating processes to be cost and performance competitive with existing commercial vapor-deposition technology. The brightness and color-uniformity specifications for flat-panel displays present challenging thickness and uniformity requirements for solution-coated AMOLED layers. Using a wide variety of custom modeling and analytical approaches, we have developed short- and long-range film-thickness control and uniformity that is commercially viable at large glass sizes. These coating technology improvements should extend to other solution-based applications as well.
