实验结果表明,不同形成电压的样品的起始亮度和工作寿命按高低的排列顺序随工作电压的增加表现出有规律的变化。还发现形成电压不问的DCEL器件在AC条件下的发光特性随工作电压的提高逐渐趋向一致,形成电压的影响逐渐消失。这一现象被解释为是由于在AC条件下也存在类似于在直流(DC)条件下的形成过程,即Cu~+迁移过程。老化过程也是形成过程的继续。 The experimental results show that the initial brightness and working life of different voltage-forming samples show a regular change with the increase of working voltage according to the order of the high and low. It was also found that the formation of voltage does not ask the DCEL device under the AC conditions, the luminescence characteristics of the working voltage increases with the trend toward the same, the formation of the voltage gradually disappear. This phenomenon is explained by the fact that there is also a formation process similar to that under direct current (DC) under the AC conditions, that is, the Cu ~ + migration process. The aging process is also the continuation of the formation process.
