Future Possibilities of OLED

FIGURE 2.11. Molecular structures of organic solid-state laser materials. 

In this chapter, we showed that OLED performance is clearly defined based on the simplified working mechanism of carrier injection and successive SCLC. The balance of holes and electrons injected within an emitter layer is a major factor contributing to overall EL quantum efficiency. The unipolar-charged-transport layers, HTL and ETL, contribute to the increase of quantum efficiency. 

We reviewed HTM, ETM, EM, and DM developed in the past 10 years and discussed the materials design of them from the aspect of high luminance, low driving voltage, and high duration. 

Recent developments in OLEDs have established a new category of organic semiconductors. Thus, we are now faced with the chance of establishing new organic semiconductor physics and to create new organic semiconductors.
