有机发光二极管的热分析与热设计
Thermal Analysis and Thermal Design of Organic Light-emitting Diode
摘要
采用基于计算流体动力学的热学模拟仿真与瞬态热学测试技术分析了OLED的热学特性,研究并讨论了输入功率、面板取向、风速等实际应用变量对OLED面板结温的影响。研究结果表明,OLED的结温与衬底及封装盖表面存在明显的温度梯度,且此温度梯度随输入电流增加大幅增大。OLED的热学特性与面板取向、气流速度密切相关。
Abstract
Computational fluid dynamic (CFD) based thermal simulation and transient thermal measurement are utilized to evaluate the thermal performance of OLED in this paper. The effects of input power, panel orientation and air velocity on the thermal characteristics of OLED are investigated and discussed. It is found that obvious thermal gradient exists between junction and substrate or glass cover, and the thermal gradient increases obviously with the input power. The thermal characteristic has a close relationship with the orientation of OLED panel and air velocity.
