Claim:
1. A backlight module comprising: a back plate; a side-type light source, comprising a light strip, wherein the light strip comprises a printed circuit board and a plurality of light sources assembled on the printed circuit board; a light guide plate, disposed on the back plate, wherein the light guide plate has an incident plane and an emitting plane, and the incident plane faces toward the side-type light source; a quantum bar, disposed between the light guide plate and the side-type light source via a fixing bracket; wherein the fixing bracket is a hollow cylinder, and comprises an accommodating space defined in the fixing bracket for installing the quantum bar, a first window faced toward the light guide plate and a second window faced toward the side-type light source, and a length of the second window is equal to the length of the light strip; wherein the side-type light source further comprises at least one support beam disposed on the printed circuit board, each the support beam is disposed between neighboring two of the plurality of light sources and thereby the at least one support beam and the plurality of light source are alternately arranged, and a length of each the support beam is less than or same as a width of the second window, and a height of each the support beam is not less than a height of each the light source, and the light strip is assembled in the second window and whereby the at least one support beam separates the plurality of light sources from the quantum bar installed in the accommodating space; wherein the first window is an opening from a first end to a second end of the fixing bracket, the second window is a long-strip continuous opening and has side frames respectively on the first end and the second end of the fixing bracket, the first window and the second window both are communicated with the accommodating space, the area of the first window is larger than the area of the second window.
