22 September 2015 R2R processed flexible OLEDs for lighting
Author Affiliations +
The authors have successfully fabricated flexible OLEDs by fully R2R process, which started from film washing, gasbarrier layer deposition, planarization, vacuum depositions of core-layers and finally encapsulated with film lamination. Influence of fabrication conditions on OLEDs performance has been studied and R2R fabricated OLEDs showed good performance almost comparable with sheet to sheet (S2S) processed OLEDs by controlling fabrication conditions. This indicates that reduction of device performance caused by the fabrication process has been minimized. Other important issues such as encapsulation, protection layers for moisture permeation and R2R related mechanical stress damage have been studied.
