Abstract
The data-line driver circuit receives data currents from an external signal source and drives the pixel group of electro-luminescence display device. The data-line driver circuit has a first circuit group, a second circuit group and a shift register. The shift register controls the first circuit group to receive the data currents and controls the second circuit group to duplicate the data currents and then send them to the pixel group.
