摘要

含有半透明金属顶部阴极和高反射阳极的顶部发射有机发光二极管（TEOLED）由于其高开口率、良好的色纯度和高效率等许多优点，已被积极研究用于显示应用。本研究综述了有机发光二极管（OLED）显示器中使用的TEOLED的技术设计，包括微腔效应的光学理论、光学损耗以及珀尔效应在光学计算中的重要性。还讨论了解决TEOLED高效率和低驱动电压的关键方法。

Technical status of top-emission organic light-emitting diodes

Top-emission organic light-emitting diodes (TEOLEDs) that contain semi-transparent metal top cathodes and highly reflective anodes have been actively researched for display applications due to their many advantages such as their high aperture ratio, good color purity, and high efficiency. In this research, the technical design of TEOLEDs used in organic light-emitting diode (OLED) displays is reviewed, covering the optical theory with the microcavity effect, optical losses, and the importance of the Purcell effect in the optical calculation. The key methodologies for addressing the high efficiency and low driving voltage of TEOLEDs are also discussed.
