Backlight module

The utility model discloses a backlight module. The backlight module comprises a back plate, a backlight source arranged in the back plate, a light guide plate arranged in the back plate corresponding to the backlight source, a reflecting sheet arranged between the light guide plate and the back plate and an optical membrane arranged on the light guide plate. The backlight source comprises a flexible circuit board and an LED lamp welded to the flexible circuit board, and the LED lamp is a long-strip LED lamp. The backlight source of the backlight module is formed by the single long-strip LED lamp, so that the LED lamp in the backlight source is next to the light guide plate, the light leakage phenomenon caused by irregular LED lamp welding in the prior art is avoided, and the backlight module is good in light-emitting evenness and high in luminance; meanwhile, the flexible circuit board where the LED lamp is welded is only provided with a single line, the structure is simple, processing is convenient, and the production efficiency is improved while the production cost is easily reduced; the backlight module brings convenience to large-scale production.
