研究目的
Investigating the application and performance of high-efficiency internal extraction structure (IES) substrates in OLED lighting, focusing on mass production technologies and their impact on device efficacy and color quality.
研究成果
The OCEANCLEAR series IES substrates enable mass production of high-efficiency OLED lighting devices, achieving significant improvements in power efficacy and color quality. The study demonstrates the potential of IES substrates in both general and specialized lighting applications, with a notable example being the candlelight-style desk lamp.
研究不足
The study highlights the need to balance the weight ratio of nanocrystals and carrier resin to avoid issues like electrical leakage or short circuits. The thermal stability of carrier resins is also a critical factor for mass production.
