Description

ABSTRACT:
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.
