An organic electroluminescent module is disclosed. The organic electroluminescent
module comprises a plurality of scan lines, a plurality of data lines perpendicular
to the plurality of scan lines, a plurality of light emitting diodes formed at
cross regions of the plurality of scan lines and the plurality of data lines, a
scan driver having inverse voltage applying transistors and ground voltage applying
transistors respectively connected to the plurality of scan lines, a data driver
having static current sources and ground voltage applying transistors respectively
connected to the plurality of data lines, and a driver controller for controlling
the scan driver and the data driver. Impurities in the organic EL module can easily
be eliminated by an inverse voltage. As a result, a lifetime of the organic EL
module can be prolonged and quality of display can be improved.
