Brief description of the drawings
Fig. 1 is broken section Fig. 1 of backlight module in the utility model；
Fig. 2 is broken section Fig. 2 of backlight module in the utility model.
Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, which show a kind of backlight module provided by the utility model, including backboard 1, light source 2 and center
3, the backboard 1 is concave, is sequentially laminated with the first reflector plate 4 in the receiving space in the spill of backboard 1 from the bottom up, leads
Tabula rasa 5 and optical film 6.The center 3 includes frame portion 31 and the supporting part 32 with the bending forming of frame portion 31, the frame portion
31 abut with the lateral surface of backboard 1 so that center 3 coats backboard 1, the receiving space that the supporting part 32 and backboard 1 are formed to
First reflector plate 4, light guide plate 5 and optical film 6 are coated to fix its displacement in thickness direction.The supporting part 32 is remote
The side of backboard 1 is additionally provided with anti-dazzling screen 7.
The light source 2 includes LED and FPC, the medial surface of backboard 1 is arranged on by heat conduction glue, more specifically
Ground, the light guide plate 5 have a bottom surface, an exiting surface and four sides, and wherein at least one side is as incidence surface, the light source
2 are arranged at least on a medial surface of backboard 1, the incidence surface of corresponding light guide plate, and the light that light source 2 is sent enters light guide plate 5, led to
Cross light guide plate and carry out equalizing light rays formation area source.
The center 3 is glue frame or metal frame, as a further improvement, the supporting part 32 is close to the side of backboard 1, right
The top of light source 2 is answered to open up groove 321, the groove 321 is to accommodate the second reflector plate 8, and second reflector plate 8 is by two-sided
For paste adhesive in the groove, the light that light source 2 is sent can effectively improve the bright of backlight by the reflex of the second reflector plate 8
Degree, reduce absorption of the center 3 to light.Preferably, the depth of the groove 321 is more than second reflector plate 8 and tacky on two sides
The 0.03-0.05mm of gross thickness, to prevent the edge of supporting part 32 from light leak occurs.
As a further improvement, the distance d at the groove 321 and the edge of supporting part 32 is more than 1.0mm to prevent from holding
