Abstract:
Disclosed are a device and method for measuring an organic light emitting diode, which measures an amount of energy for compensating for a burn-in of an organic light emitting diode, by sensing a charged voltage of a sensing line connected to the organic light emitting diode. The device for measuring an organic light emitting diode includes an external current source, and is configured to measure an amount of energy for compensating for a burn-in, by sensing a charged voltage of a parasitic capacitor of a sensing line.
