Fundamentals of OLEDs
2017
This chapter describes fundamentals of OLEDs, including the principles, the fundamental device structures and some features of OLEDs.OLED is a carrier injection type electroluminescent device, having a similar emission mechanism to the inorganic light emitting diode (LED). The fundamental device structure of OLEDs is very simple, consisting of an anode, some organic layers and a cathode. The OLED has several attractive features such as low driving voltage, high efficiency, wide color variation, and fast response speed.
