An organic light emitting device and an operation method thereof are disclosed. The disclosed organic light emitting device may include a magnetoresistive element and an organic light emitting element electrically connected to the magnetoresistive element. The organic light emitting diode includes at least a magnetic field applying unit for applying a magnetic field to the magnetoresistive element, a power source for supplying a current between the magnetoresistive element and the organic light emitting element, And may further include a current source. The organic light emitting element may include an exciplex material. According to another embodiment, the organic light emitting element may comprise a magnetoresistive element and two organic light emitting elements electrically connected thereto. In this case, the emission color may vary depending on the intensity of the magnetic field applied to the organic light emitting device. |
