This paper presents different factors that affect the life time of OLEDs. Phosphorent OLEDs were found to exhibit longer lifetime by utilizing triplet states along with the singlets. Interface conditioning and mixed host with double emission layers have been found to improve the life time by preventing the degradation of the interfaces due to electrochemical reactions. Hence charge balance and exciton confinement were found important. Multiline addressing scheme (MAS) for passive matrix OLED displays was also studied and it was found that, minimizing the amplitude of the electrical current flowing through the diodes has a direct impact on the lifetime.
