Abstract
A LED backlight module includes a substrate, a heat-dissipating plate, a LED string and a backlight driving circuit. The LED string includes plural LEDs. The LED string further includes a positive driving terminal, a negative driving terminal and a connecting terminal. A positive output terminal, a negative output terminal and a zero voltage terminal of the backlight driving circuit are respectively connected with the positive driving terminal, the negative driving terminal and the heat-dissipating plate, so that a positive driving voltage and a negative driving voltage are generated by the backlight driving circuit to drive illumination of the LED string. A first number of LEDs of the LED string are electrically connected between the connecting terminal and the positive driving terminal. A second number of LEDs of the LED string are electrically connected between the connecting terminal and the negative driving terminal.
