The anodes are injected into Alq3 hole through TDP when using low DC voltage, and captured by Alq3 together with the electrons injected into the Alq3 through cathodes to form up excitonic pairs, and the excitonic compounding produces radioluminescence.

在加较低直流偏压时，阳极通过 TDP 注入到 Alq3 的空穴，与阴极注入到 Alq3 的电子被Alq3 捕获形成激子对、激子复合产生辐射发光。

This is a steady-state DC parameter that applies after the power supplies have ramped up.

这是一个稳定的状态参数，直流电源后，都已在加大适用。
