Flexible Organic Light-Emitting Diode Display Coming Soon
June 1, 2009 12:01 PM | Technology | Comments (0)
The Flexible Display Center (FDC) at Arizona State University and Universal Display Corporation today introduced the first a-Si:H active matrix flexible organic light-emitting diode (OLED) display to be manufactured directly on DuPont Teijin’s polyethylene naphthalate (PEN) substrate. Implementing Universal Display Corporation’s phosphorescent organic light-emitting diode (PHOLED) technology and materials and the FDC’s proprietary bond-debond manufacturing technology, the 4.1-inch monochrome quarter video graphics array (QVGA) display represents a significant milestone toward achieving a manufacturable solution for flexible OLEDs. |  |
Additional advantages of the technology include lower operating temperature due to less heat being generated, easier to drive, longer battery life, and more stable transistors.
The flexible backplane display was manufactured at the Flexible Display Center utilizing a 180°C thin film transistor process. The FDC’s facility implements traditional flat panel and semiconductor tools and processes to achieve flexible displays, enabled by its proprietary bond-debond technology to secure the plastic substrate to a rigid carrier during manufacture.
The integration of Universal Display’s PHOLED frontplane delivers a key enabling technology for the flexible OLED. The PHOLED materials allow the OLED to convert up to 100 percent of the electrical energy into light, as opposed to traditional fluorescent OLEDs which convert only 25 percent, providing up to four times more energy efficiency. Universal Display integrated the FDC backplane designed for its PHOLED frontplane to produce the display.
The FDC and Universal Display will present a paper discussing the active matrix flexible OLED on Friday, June 5th, in session 65.4 at SID 2009. Additionally, the FDC will demonstrate this device and other flexible display technologies in booth #523 at the show. Universal Display, located at booth #676 at the show, and DuPont Teijin are members of the Flexible Display Center.
