[0019] See Figure 4 versus Figure 5 , Is a schematic diagram of the structure of the backlight module of the present invention and a schematic diagram of the brightness distribution of the light guide plate. The backlight module includes a set of linear light sources 10, a set of reflectors 11 arranged around the linear light sources 10, a light guide plate 20, and a light-enhancing sheet 25. The light guide plate 20 includes a light incident surface 201, a light exit surface 203, and a bottom surface. 202. The line light sources 10 are respectively located on the sides of the light incident surface 201 of the light guide plate 20. The light emitted by the linear light source 10 is transmitted in the light guide plate 20, reflected multiple times between the light incident surface 201 and the bottom surface 202, and finally exits the light exit surface 203 and enters the light enhancement sheet 25. The line light source 10 may be a CCFL (Cold Cathode Fluorescent Lamp, cold catho...
