Tracepro在OLED微透镜设计中的应用

有机电致发光从最初进行的研究直到今天,在许多方面都有了很大的突破,但目前仍存在着一些困难,例如器件的寿命就是比较关键的问题。如果器件具有较高的发光效率,便可在出射光子数相同的情况下,减少电子数的注入,从而降低了器件的焦耳热,提高了器件的寿命,所以提高OLED的量子效率是解决器件寿命问题的关键所在。利用微透镜提高器件的外量子效率可以取得明显的效果。本文探讨了Tracepro在OLED微透镜设计中的应用。

Tracepro Applied in the Design of the Miccrolens

The paper focuses on the air/substrate interface to enhance the external quantum efficiency of organic light-emitting devices. It is reported that a method enhances the external quantum efficiency of organic light-emitting devices, employing microlens arrays based on the soft-lithography. The structure parameters of the microlens array are important for the refractive microlens arrays to enhance the external quantum efficiency of organic light-emitting devices.A theoretical model based on Tracepro is developed to simulate the effects and optimize the structure parameters of the microlens array.The external quantum efficiency of organic light-emitting devices with microlens arrays is measured in this paper and the efficiency enhancement is obtained.
