Driving apparatus of electroluminescent display device and driving method thereof
First Claim
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 a scan pulse of which a polarity has been reversed by a certain unit to the scan lines; and
a data driving unit for receiving a voltage from a single data voltage source and supplying a data pulse to the data lines.

Abstract
A driving apparatus of an electroluminescent display device includes: a scan driving unit for receiving a voltage from a single voltage source and sequentially supplying a scan pulse of which polarity is reversed by the frame unit to scan lines; and a data driving unit for receiving the voltage and sequentially supplying a data pulse with an opposite polarity to the polarity of the scan pulse to data lines. An optimum voltage to a pixel cell can be supplied by completely removing electric charges charged in the pixel cell by reversing a positive pulse or a negative pulse generated by a single power source by the frame unit and supplying it to each data line and scan line.
