Abstract:
1. A driving apparatus for an electro-luminescence display device comprising: a display panel having a scan line connected to a cathode, a data line connected to an anode and intersecting the scan line and supplied with a data, and a light-emitting device positioned at the intersection between the scan line and the data line; a data driver configured to supply a data to the data line; and a scan driver configured to apply a high voltage scan pulse to the scan line, the high voltage scan pulse including a first current value during a rise period of the high voltage scan pulse and a second current value during a period of the high voltage scan pulse subsequent to the rise period, the first current value being higher than the second current value, wherein the scan driver includes a first switch configured to supply a scan high voltage; and a second switch for selectively supplying a ground voltage to the scan line, and wherein the second switch has a first channel width during said rise period while having a second channel width smaller than said first channel width during said period of the high voltage scan pulse subsequent to the rise period.
