Specific embodiment

Feature of the present utility model and principle are described in detail below in conjunction with accompanying drawing, illustrated embodiment is only used for explaining The utility model, not limits protection domain of the present utility model with this.

As shown in Fig. 3-Figure 12, the present embodiment provides a kind of backlight module, including light guide plate, the back of the body on the outside of light guide plate Plate 2 and the glue frame 1 on the outside of the backboard 2,

The backboard 2 is included positioned at the Part I 21 of the light guide plate bottom and positioned at the second of the light guide plate side Part 22, the Part I 21 are provided with away from one end of the Part II 22 and are connected with the first of 1 phase clamping of the glue frame Portion；

The glue frame 1 includes outside and the Part III of light guide plate surrounding for enclosing the Part II 22 located at the backboard 2 12nd, and positioned at the Part IV 13 of the light guide plate bottom, the Part IV 13 is provided with and the first connecting portion phase The second connecting portion of clamping.

The setting of first connecting portion and second connecting portion, for undersized display in, increased the area of backboard 2, So as to heat radiation performance, and backboard 2 is cooperated with glue frame 1, enhances the intensity of 1 junction of backboard 2 and glue frame.

The specific constructive form of the second connecting portion can have various, as long as realizing the connection of backboard 2 and glue frame 1 i.e. Can, in the present embodiment, the second connecting portion with the first surface 10 away from the light guide plate and with the first surface 10 The second surface 11 being oppositely arranged,

The first surface 10 to form the be connected with the first connecting portion to being recessed near the direction of the light guide plate One joint face 103,

First joint face 103 is provided with multiple openings, along it is multiple be open to the second surface to extend to be formed through institute State multiple through holes 101 of second connecting portion；

The first connecting portion is provided with the projection 20 corresponding with 101 quantity of the through hole to coordinate with the through hole 101 Clamping, surface and the second surface 11 of described raised 20 close light guide plate are same plane.

In order to further enhance the intensity of backboard 2, the through hole 101 is located at the port of the second surface 11 and has one To the breach 102 that the direction away from the backboard 2 extends；

Described raised 20 are provided with the chimb 202 being connected with the breach 102 near one end of light guide plate.
