一种工业级聚萘二甲酸乙二醇酯（PEN）基板被探索作为一个简单的，具有成本效益的高效率有机发光二极管（OLED）的平台。其高折射率与工业级版本固有的内置散射特性相结合，无需任何额外的结构或特殊光学元件即可显著增强外耦合。柔性，颜色稳定的OLED的效率接近100 lm W-1的演示。
An industrial-grade polyethylene naphthalate (PEN) substrate is explored as a simple, cost-effective platform for high-efficiency organic light-emitting diodes (OLEDs). Its high refractive index, combined with the built-in scattering properties inherent to the industrial-grade version, allows for a significant enhancement in outcoupling without any extra structuring or special optical elements. Flexible, color-stable OLEDs with efficiency close to 100 lm W-1 are demonstrated.
