Abstract:
1. A driving apparatus of an electroluminescent display device comprising: a plurality of pixel cells formed between a plurality of scan lines and data lines; a scan driving unit for receiving a voltage from a single scan voltage source and sequentially supplying to the plurality of scan lines a first scan pulse having a first polarity in a first frame or field and for sequentially supplying to the scan lines a second scan pulse having a second polarity opposite to the first polarity in a second frame or field such that a last scan pulse of the first scan pulse in the first frame or field substantially coincides with a beginning pulse of the second scan pulse in the second frame or field; and a data driving unit for receiving a voltage from a single data voltage source and supplying a data pulse to the data lines, wherein the data driving unit supplying the data pulse having the second polarity at a same time the scan driving unit supplying the first scan pulse having the first polarity, and the data driving unit supplying another data pulse having the first polarity at a same time the scan driving unit supplying the second scan pulse having the second polarity.
