Abstract :
This paper presents a new theoretical equivalent model (TEM) for organic light-emitting diodes (OLEDs). The parameters of TEM are identified using a simple characterization procedure based on auxiliary circuits and low-cost equipment. From this TEM, a method for intrinsic capacitance identification is proposed. This model is useful to simulate and analyze OLED devices considering dynamic and steady-state operation conditions. In addition, it provides guidelines for manufacturers and lighting designers to enhance the device performance and to design dedicated OLED drivers. In order to validate the proposal of this paper, four commercial OLEDs are tested, and the comparison between the theoretical and the experimental results is satisfactory.
