1Reliability
If conventional organic thin film materials are used in OLEDs, then device structure and manufacturing process remain simple, but efficiency and lifetime are insufficient
Solution Approach 1:
The patent employs composite organic thin film materials consisting of multiple layers with distinct functions (hole injection layer, hole transport layer, light emitting layer, electron transport layer, electron injection layer). Each layer is composed of specific organic compounds with tailored molecular structures and properties, creating a composite material system that optimizes both efficiency and lifetime while managing complexity through functional segmentation
Solution Approach 2:
The patent applies local quality by designing different organic thin film layers with specific localized properties - each layer contains compounds with particular HOMO/LUMO energy levels, charge transport characteristics, and stability properties matched to its specific function within the OLED structure, thereby improving overall device performance without uniformly increasing complexity
