  • Organic electroluminescence display and method of operating the same
    Patent number: 7868865
    Abstract: An organic electroluminescence display and a method of operating the organic electroluminescence display are disclosed. A pixel array unit, including a plurality of pixels, is divided into at least two pixel groups adjacent to each other. The first pixel group is selected by a first scan driving unit and the second pixel group is selected by a second scan driving unit. Scanning lines for selecting the first pixel group extend into the first pixel group and scanning lines for selecting the second pixel group extend into the second pixel group. Accordingly, each scanning line is reduced in length and thus impedance of the scanning line is decreased. The reduction of impedance prevents delay or distortion of scan signals.
