Abstract
The present invention provides a driving circuit, a backlight module and a display apparatus using the same. The driving circuit comprises a first inductor, a second inductor, a first power switch, a second power switch, a driving circuit unit and a push-pull circuit. The first inductor and the second inductor are connected between the light-emitting diodes and a power supply. The first power switch is connected between the first inductor and the light-emitting diodes. The second power switch is connected between the second inductor and the light-emitting diodes. The push-pull circuit is connected to the first power switch and the second power switch. The driving circuit unit is connected to the push-pull circuit. An electrolytic capacitor or a capacitor having high capacitance can be omitted in this invention.
