  • Apparatus for improving uniformity of luminosity in flat panel display
    Patent number: 7580034
    Abstract: A flat panel display includes a plurality of pixel anode electrodes arranged in a display area. A plurality of anode electrode lines for supplying a driving current to the pixel anode electrodes are connected at one end to pixel anode electrodes, and at the other to one or more current supply lines of a current supply line assembly. The current supply lines, in turn, are connected to first and second terminals to which the driving current is applied. The current supply line assembly also includes an impedance adjusting means for adjusting impedance of at least one of the first and second supply lines. The impedance adjusting means may be configured as a third separate supply line connected to at least one of the first and second supply lines, and the impedance of the current supply line is adjusted by varying the length or width of the third current supply line.
