The present invention provides a back frame, which includes at least two primary assembling pieces, and the at least two primary assembling pieces are joined to form a main frame structure of the back frame. The back frame further includes positioning walls, and the positioning walls are mounted to a side wall of at least one of the primary assembling pieces to define a receiving space for receiving an LED light bar. The present invention also provides a backlight system. With the above described manner, the back frame and the backlight system of the present invention form a back frame through joining so as to make structure of the back frame simple and save the material for the back frame so as to lower down the cost of flat panel display device. Further, the present invention uses a primary assembling piece that is provided with positioning walls to precisely and effectively position an LED light bar thereby simplifying assembling and increasing assembling efficiency.
