Abstract
A driving method of external electrode fluorescent lamp inverter for backlight. In the driving method, a square wave voltage frequency for driving the external electrode fluorescent lamp is applied to the primary side of a transformer in the region whose frequency is substantially ½ of the resonant frequency which is determined by the capacitance of the external electrode fluorescent lamp and the leakage inductance of the transformer. Then, the external electrode fluorescent lamp is caused to emit light by the self-discharge to thereby obtain high efficiency and high luminance. The driving method of external electrode fluorescent lamp inverter for backlight includes applying a square wave voltage for driving an external electrode fluorescent lamp to the primary side of a transformer; and applying the square wave voltage to the primary side of transformer in a region where the frequency thereof is substantially ½ of a resonant frequency, which is determined by the capacitance of the external electrode fluorescent lamp and the leakage inductance of the transformer, and thus causing the external electrode fluorescent lamp to emit light by the self-discharge.
