COLD CATHODE FLUORESCENT LAMP, COLD CATHODE FLUORESCENT LAMP DRIVING APPARATUS, COLD CATHODE FLUORESCENT LAMP APPARATUS, LIQUID CRYSTAL DISPLAY APPARATUS, CONTROL METHOD FOR COLD CATHODE FLUORESCENT LAMP, AND CONTROL METHOD FOR LIQUID CRYSTAL DISPLAY APPARATUS

摘要

A cold cathode fluorescent lamp apparatus is disclosed wherein a cold cathode fluorescent lamp can be lit readily and leak current is minimized. A pair of internal electrodes are disposed on an inner face of the cold cathode fluorescent lamp, and a pair of external electrodes are provided on an outer face side of the cold cathode fluorescent lamp. The internal electrodes are driven by a dc driving circuit, and the current to flow between the internal electrodes is controlled by a constant current circuit. The external electrodes are driven by an ac driving circuit.
