  • Patent number: 7450094
    Abstract: The present invention relates to a light emitting device where currents passing through scan lines have the same values. The light emitting device includes data lines, scan lines, pixels, one or more dummy data line and a cross-talk preventing circuit. The data lines are disposed in a first direction, and the scan lines are disposed in a second direction. The pixels are formed in cross areas of the data lines and the scan lines. The dummy data line is disposed in the first direction. The cross-talk preventing circuit provides a compensating current to scan line related to luminescence of the scan lines through the dummy data line so that total sum of current passing through the scan line has a desired value. In the light emitting device, currents passing through scan lines have the same values, and so a cross-talk phenomenon is not occurred to a panel.
