Electrical characterization and fabrication of OLED

Abstract

One of the most motivating areas of scientific research in printed electronics is Organic Light-Emitting Diode (OLED). They are engaging for use in next generation display and lighting technologies. In display applications, OLEDs have a broad range of emission colour and high power efficiencies in pliable substrates. In lighting applications, OLEDs appealing features such as broadband emission and inexpensive manufacturing process. The aim of this paper is to characterize and fabricate a double layer OLED. The emitting layer of the device is Poly [2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (MEH: PPV). The electrical characterization of the double layer OLED is performed using ATLAS tool. The thicknesses of the two layers are swept to show their effect on the OLED electrical characterization. In addition, two different devices with different thicknesses are fabricated using wet process. The electrical characteristics of the fabricated devices are measured and compared with the
simulated one.
