Abstract

The development of OLED displays is a non-ergodic process in which there is continuous novel change; and comprehending emitters that are evolving requires new theory, or at least modification of that which is already possessed.  For the first time, a new data-validated closed-form physics-based expression is derived for the I-V characteristics of OLEDs in this paper. Two parameters emerge from the new model: liminal current and liminal voltage.  Both parameters are expressed in terms of device and material parameters, allowing a device engineer to intuitively design experiments to target low voltage operation OLEDs.  Robust parameter extraction methods are proposed and validated with experimental data
