Using this modified simulator, we can demonstrate the characteristics of OLEDs including current-voltage curve, quantum efficiency performance, time-resolved electroluminescence spectrum, and electric profile...etc. Also, this solver can be used to explain the mechanism of hyper-TTF OLEDs, and analysis the loss from different exciton mechanism. Furthermore, we can do further optimization for TTF-OLEDs to achieve an internal quantum efficiency increasing of 23% (from 29% to 36%). |
