摘要

蓝色有机发光二极管（OLED）的低压工作对于降低功耗和提高器件寿命至关重要。本综述简要概述了低电压电致发光的历史和起源，以及近期报道中实现低电压电致发光的情况。特别是上转换 OLED，它利用电荷转移态作为中间态，通过三重三重湮灭促进蓝光发射，是一种很有前景的解决方案。因此，旨在降低驱动电压的持续努力，包括对新材料和器件结构的探索，有望为扩大蓝色有机发光二极管的应用范围做出重大贡献。

Low-voltage turn-on in blue organic light-emitting diodes

The low-voltage operation of blue organic light-emitting diodes (OLEDs) is critical for reducing power consumption and improving device lifetime. This review briefly summarizes the history and origin of low-voltage electroluminescence and its realization in recent reports. In particular, upconversion OLEDs, which use the charge transfer state as an intermediate state to facilitate blue emission via triplet–triplet annihilation, present a promising solution. Thus, continued efforts aimed at reducing the driving voltage, including the exploration of new materials and device structures, are expected to significantly contribute to expanding the applications of blue OLEDs.
