Ruggedized Full-Color Flexible OLED Display
Abstract
The objective of this program was to demonstrate a flexible, rugged, bright and efficient phosphorescent OLED technology with a low cost manufacturing path. The team comprised Universal Display Corporation, Princeton University, the University of Southern California, Penn State University, L3 Displays and Vitex Systems, and was led by Universal Display Corporation (PI: Michael Hack). The program focused on developing the technology to enable reliable low power consumption flexible (FOLED(Trademark)) displays to be fabricated on plastic substrates. This involved the integration of phosphorescent OLEDs (PHOLED(Trademark)) with multi-layer permeation barriers deposited over the substrate and also as a thin film encapsulant over the OLED to prevent degradation by oxygen or moisture. Additional tasks were development of large area, low cost organic vapor phase deposition (OVPD(Trademark)) fabrication technology, along with novel approaches to demonstrating bistable OLED pixels for advanced displays with reduced information bandwidth requirements. Accomplishments included the demonstration of thin film encapsulated OLED pixels on plastic substrates with lifetimes exceeding 2,000 hours, the delivery to the government of monochrome, phosphorescent OLED passive-matrix displays on plastic substrates, high performance OLEDs and TFTs grown using OVPD, and bistable OLED pixels fabricated from both a novel integrated organic OLED (TOLED(Trademark)) integrated with an organic photodetector, as well as a second approach utilizing OLEDs and amorphous silicon TFTs.
