Abstract
A LED backlight driving circuit includes a plurality of driving integrated circuits coupled to a data transmission line and a plurality of selecting circuits respectively connected to the plurality of driving integrated circuits. In an addressing mode, the plurality of selecting circuits are used to select one driving integrated circuit from the plurality of driving integrated circuits to set an address. The plurality of driving integrated circuits can set addresses via input/output pins connected to LEDs. So a number of pins of the driving integrated circuit can be equal to or less than 4, which will rise a yield of the LED backlight driving circuit setting in a PCB or in a glass board.
