为了短时间内获得白光有机发光显示器(OLED)的可靠性寿命信息
通过对其开展三组恒定电流应力加速寿命试验采集样品失效试验数据
应用对数正态分布函数描述白光OLED的寿命分布。在图分析法(MAM)的基础上
基于自行开发的寿命预测软件
绘制了对数正态概率双坐标纸
计算出白光OLED的平均寿命和中位寿命。数值结果表明
白光OLED寿命服从对数正态分布
加速寿命方程符合逆幂定律
精确计算的加速参数使得对其寿命的快速估算成为可能。结果可为生产厂商和用户提供参考和指导。
In order to obtain the reliability life information of the white Organic Light-Emitting Diode (OLED) in a short time
failure data of OLED samples were collected by carrying out three groups of constant current stress accelerated life tests
and the lognormal distribution function was applied to describing the life distribution. The evolution of OLED's average life and the median life were achieved by applying the lognormal distribution to describing the life
and the self-developed life prediction software to plotting double coordinates' paper of lognormal probability
which based on map analysis method (MAM). Numerical results indicate that white OLED's life follows the lognormal distribution
that the acceleration model is consistent with inverse power law
and that the acceleration parameters which are accurately calculated make fast estimation of white OLED lifetime possible
which provides some significant guideline to its manufacturers and customers.
