  • Publication number: 20060238134
    Abstract: An electro-luminescence display device includes: an electro-luminescence display panel including red, green and blue subpixels in regions defined by a plurality of data lines and a plurality of scan lines; a scan driver integrated circuit for driving the scan lines; and a data driver integrated circuit for driving the data lines, wherein the data driver integrated circuit has no more output channels than half of the plurality of datelines.

  • Publication number: 20060071883
    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.

  • Publication number: 20050237280
    Abstract: An electro-luminescence display device includes an electro-luminescence display panel having pixel cells arranged at intersections of a plurality of data electrode lines and a plurality of scan electrode lines, the scan electrode lines being in a unit of at least two electrode lines, and each of the pixel cells along a same row being connected to at least one scan electrode line of a corresponding scan electrode line unit, and a multiplexer for selectively applying data signals to at least two of the data electrode lines during a time period.
