以有机发光二极管(Organic light-emitting diode, OLED)等为代表的新型显示技术已成为新一代信息技术的先导性支柱产业。尽管OLED在材料与器件叠层设计工艺等核心技术上已取得巨大突破,但目前业界研发仍然主要依靠试错法(trial-and-error),对于器件内部物理机理的理解仍然处于定性、经验性的阶段。本文系统性地阐述了OLED器件物理理论,特别是对如何从物理上描述组成OLED器件的非晶无序分子体系、如何描述电荷传输和激子过程、如何计算器件光电性能、以及如何将物理理论应用于实验OLED研发,进行了详细的介绍。
New display technologies such as organic light-emitting diodes (OLEDs) have become a key industry of information technology. Although great breakthrough has occured in OLED technologies such as materials and stack design processes, currently the research and development still mainly rely on trial-and-error approaches, and the understanding of the physical mechanism of the device remains mostly qualitative and empirical. In this article, the physical theories of OLEDs are systematically introduced and reviewed, especially focusing on how to physically describe the amorphous disordered nature of molecular systems, how to describe charge transport and excitonic processes, how to calculate the optoelectronic properties of devices, and how to apply these theories to experimental OLED research and development.
