摘要
设计了结构为"基板/ITO/有机发光层/金属阴极"的可弯曲式(柔性)有机电致发光器件(FOLED),利用TracePro光学软件对FOLED在平整和弯曲时的出光情况作了仿真,得到了器件在两种情况下的照度图和发光强度分布图。研究发现:在弯曲时,器件出射光的光通量、照度、发光效率都要比平整时大;同时发现器件在平整和弯曲两种情况下,出射光的发光强度随角度分布情况也不一样。对这些变化从理论上作了解释。
Flexible organic light-emitting devices（FOLEDs） with a structure of flexible substrate/ ITO/ organic layer/ Ag was designed,the out-coupling of the FOLEDs with excurved or flat substrate was simulated with TracePro softare,and the plots of illuminance and luminous intensity distribution were presented.It was found that： the luminous flux,illuminance and out-coupling efficiency of the device are higher when its substrate is excurved.The luminous intensity distribution is also different under the two conditions.The explanations for the diference are made in theory.
