Current-Voltage Characteristics of Organic Light-Emitting Diodes Depending on the Application of Forward-Reverse Bias Voltage

We have investigated current-voltage(I-V) characteristics of organic light-emitting diodes based on TPD/Alq 3 organics depending on the application of forward-reverse bias voltage. Luminance-voltage characteristics and luminous efficiency were measured at the same time when the I-V characteristics w...

Description
Summary:We have investigated current-voltage(I-V) characteristics of organic light-emitting diodes based on TPD/Alq 3 organics depending on the application of forward-reverse bias voltage. Luminance-voltage characteristics and luminous efficiency were measured at the same time when the I-V characteristics were measured. We have observed that the I-V characteristics were measured. We have observed that the I-V characteristics shows a current maxima at low voltage, which is not related to the emission from Alq 3 .
