65‐1: Invited Paper: Diverse Effects of Defects on the Performance of Organic Light‐Emitting Diodes
Jaesang Lee- General Medicine
Defects in organic light‐emitting diodes (OLEDs) generate the electronic states whose energy level are usually found in the energy gap of OLED materials. Hence, defects can disturb the movement of, and sometimes eliminate, the charges and excitons in OLEDs. Here, we discuss how the properties of the defects, i.e., their originating positions, energy levels and densities, affect the dynamics of the charges and excitons, thereby determining the electrical and optical performance of the comprising OLEDs.
