Organic light emitting diodes (OLEDs) are used in displays and other applications because of their advantages such as light weight, low power consumption, and high contrast. In this study, we investigate the charge behavior of blue OLEDs, which use triplet-triplet annihilation (TTA) as the emission mechanism, during operation using electronic sum-frequency generation (ESFG) spectroscopy.
