ABSTRACT:
An electro-luminescence display device includes a plurality of column lines, a plurality of first row lines and a plurality of second row lines. The plurality of first row lines cross the column lines and a first scan signal is supplied thereto. The plurality of second row lines intersects the column lines and a second scan signal is supplied thereto. Organic light emitting devices are formed at pixel areas which are defined by the column lines and the first and second row lines. At least two drive switches operate to drive the organic light emitting devices. The second scan signal applies later than the first scan signal to activate the drive switches. A kickback voltage is generated upon a voltage change of the first row line. A kickback compensation circuit operates to cancel the kickback voltage.
