It has long been desired to enable global structural optimization of organic light-emitting diodes (OLEDs) for maximal light extraction. The most critical obstacles to achieving this goal are time-consuming optical simulations and discrepancies between simulation and experiment. In this work. by leveraging transfer learning. https://www.itsmajorlook.com/great-deal-Chicago-Cubs-Earrings-Round-Design-p21310-limited-grab/
