Abstract
The present invention discloses organic light emitting device, manufacturing method thereof, organic light emitting display device and driving method thereof. The organic light emitting device comprises a substrate and a first electrode layer, an organic layer and a second electrode layer positioned on the substrate, the organic layer is arranged between the first and second electrode layers, the first electrode layer, the organic layer and the second electrode layer form a laminated region for emitting light in a first specific color in a positive half cycle of alternating current and an inverted region for emitting light in a second specific color in a negative half cycle of alternating current, and at least portions of projections of the laminated region and the inverted region on the substrate are not overlapped. Technical solutions of the present invention render the organic light emitting device with adjustable light color and prolonged service life.
