Experimental study demonstrates accurate static and dynamic electrical modeling in OLED lighting panels, indicating a practical tool for driver circuit design.
In this paper, a hardware emulator (HE) for organic light-emitting diodes (OLEDs) is proposed. Two OLED panels used in lighting applications are characterized based on a theoretical equivalent model (TEM). The objective is to better understand OLED operation and to infer about their electric static and dynamic behavior. From this, a HE able to represent the real behavior of an OLED panel using equivalent devices is proposed. The goal is to provide a useful tool for an adequate OLED driver design. In order to validate the HE, OLED samples were experimentally tested under static and dynamic operating conditions. The comparison between HE and OLED experimental results demonstrates a satisfactory accuracy.
