The back light module includes a plurality of light source matrixes, a current adjusting circuit and a light source driving circuit, wherein each of the light source matrixes includes N light emitting units and N is an integer greater than 1. First ends of the light emitting units are electrically connected to each other, and a second end of the ithlight emitting unit is electrically connected to an ithlevel switch line, wherein i is an integer and 1≦i≦N. The current adjusting circuit supplies and controls the current of each of the light source matrixes through level switch lines. The light source driving circuit drives the light source matrixes sequentially.
