The present invention provides a backlight system, which includes an LED light source, a back frame, and a PCB. The LED light source comprises an LED lamp and an LED substrate. The LED substrate includes, sequentially stacked, a first conductor wiring layer, a first insulation layer, an aluminum substrate, a second insulation layer, and a second conductor wiring layer and the LED lamp is mounted on the first conductor wiring layer. The back frame carries the LED light source and includes at least two primary assembling pieces. The at least two primary assembling pieces are joined to form a main frame structure of the back frame. The PCB is disposed on the second conductor wiring layer of the LED substrate. The backlight system of the present invention can reduce the cost of back frame mold and save the material and space of the back frame, so as to lower down the cost of the backlight system. |
