Abstract

In this work, we have optimized the passivation process to improve the lifetime and reliability of organic light-emitting diode (OLED) devices. A hydrophobic polymer (HPP) was used as the passivation layer and characteristics of the optimized OLED devices with the film were investigated. The HPP films exhibited excellent permeating barrier properties toward water because they were hydrophobic and had low surface energy. In addition, in OLEDs, the HPP films prevented darkspot growth on the emitting area.

使用疏水膜作为钝化层提高有机发光二极管的寿命

摘要

在这项工作中，我们优化了钝化工艺以提高有机发光二极管 (OLED) 器件的寿命和可靠性。疏水聚合物 (HPP) 被用作钝化层，并研究了具有该薄膜的优化 OLED 器件的特性。HPP 薄膜对水表现出优异的渗透阻隔性能，因为它们是疏水性的并且具有低表面能。此外，在 OLED 中，HPP 薄膜可防止发光区域上的暗点生长。
