3. Reliability
The most common definition of lifetime is the time T
1/2
after which the initial luminance L
0
(arbitrarily chosen equal to 100 cd/m
2
) is halved, at constant operating voltage. It has been shown empirically that this lifetime is related to L
0
and therefore to the initial current density :
Although the lifetime of organic electroluminescent devices is still a key issue for the industrialization of displays, considerable progress has been made (from a few minutes to several thousand...
