Abstract

The invention is applicable to the field of electroluminescence component and provides an organic electroluminescence device and a drive method thereof. The organic electroluminescence device comprises a first cathode / anode combined electrode, a first bipolar current carrier transport layer, a first luminescence layer, a current carrier barrier layer, a second luminescence layer, a second bipolarcurrent carrier transport layer and a second cathode / anode combined electrode. The organic electroluminescence device provided by the invention can accurately control the luminescence color of the device and prolong the service life of the device; simultaneously, the invention also can realize continuous adjustment of the light color and achieve two kinds of monochromatic lights and the mixed light of the two monochromatic lights; when the device produces color change due to the aging of each luminophore after operating for some time, the parameter of the AC voltage can be adjusted for calibration to improve the stability of the luminescence color; and the AC voltage drive device also can be used to release the excess current carrier and facilitating the improvement of the service life ofthe device.
