  • Publication number: 20030141829
    Abstract: A current equalizer assembly for LCD backlight panel comprises at least a differential current choke and at least a capacitor. The capacitor is arranged striding on a terminal (B) at a primary coil and on a terminal (D) at a secondary coil of the differential current choke so as to equalize the current flowing through every cold cathode fluorescent lamp (CCFL) connected to the differential current choke and the lightness thereof accordingly. Moreover, the capacitance of the stridden capacitor is replaceable by the intrinsic stray capacitance when the inductance of the differential current choke is properly selected.
