DCM1000 DC-JVL Measurement System
Current density-Voltage-Luminance (JVL) measurements are widely used to evaluate organic light-emitting diodes (OLEDs). These measurement results are mainly discussed about current density and luminance in high-voltage regions. However, it has been required to evaluate JVL characteristics in a low driving voltage region to investigate behaviors such as charge injections and emissions in OLEDs.
