Polymer Light-Emitting Diode (PLED) Process Development
Abstract
This report documents the effort and results of process development leading to a direct driven polymer light-emitting diode (PLED) display on a flexible substrate manufactured on roll-to-roll line. The challenge was twofold: i) to design and fabricate PLED specific NanoBlock integrated circuit (IC) for current driven display devices, and ii) to integrate very sensitive PLED processes (in terms of morphology and topography) with a back plane having embedded NanoBlock ICs under the PLED active area. Each NanoBlock IC provides eight independent constant current supplies for eight display pixels with capability of 4 bit gray scale. The development of integrated NanoBlock IC back plane is described in detail including the description of final optimized structure. The successful integration is documented on a segmented display driven by six NanoBlock ICs embedded in the display back plane. The results are compared with the goals of the Task 1.1.5. Also the effort to identity a web compatible coating technology for PLED materials is also provided. The report is closed with a summary of conclusions and recommendations for Phase II of the Flexible Display Program.
