Abstract
The present invention provides a driving circuit of a backlight module and a display apparatus using the same. The driving circuit comprises at least one transistor connected to light-emitting diodes (LEDs), a constant-current circuit connected to the transistor, a power resist connected to the transistor in parallel; and a power switch connected between the transistor and the power resist, wherein a switch signal is transmitted to the power switch, and a signal level of the switch signal in a three-dimensional (3D) image mode is higher than another signal level of the switch signal in a two-dimensional (2D) image mode. The present invention can be applicable to the display apparatus for raising a brightness of the backlight module in the 3D image mode.
