OLED소자의 고온에서의 가속 수명에 관한 연구

A Study on OLED's lifetime at high temperature

To application Arrhenius model for OLED's lifetime, it's needed in high temperature test. Because OLED's character is changed in high temperature, it's important to find limit temperature. We found out $40^{\circ}C$ is proper temperature by result of tests. But that is not enough acceleration to apply in practical affairs. We find new stress to get a bigger accelerated constant.
