Specific implementation mode

To make the purpose of the present invention, technical solution and advantage are clearer, below in conjunction with the accompanying drawings to embodiment of the present invention It is described in further detail.Obviously, described embodiment is a part of the embodiment of the present invention, rather than whole implementation Example.Based on described the embodiment of the present invention, those of ordinary skill in the art are obtained under the premise of without creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figs. 1-2, which show a kind of backlight module provided by the utility model, including bottom frame 1, it is set to the bottom Reflector plate 2 on frame 1, the light guide plate 3 on the reflector plate 2, corresponding to the light guide plate 3 incidence surface setting shine Component 4；The luminescence component 4 includes circuit board 41 and the multiple LED42 being electrically connected on the circuit board 41, the reflection Piece 2 extends to the bottom surface of the LED42；The reflector plate 2 corresponding to adjacent LED42 centre position on offer cutting line 21.Specifically, further include the center 5 enclosed set on 3 surrounding of the luminescence component 4 and light guide plate, the circuit board 41 fits in institute It states on center 5 and light guide plate 3.Wherein, the bottom frame 1 is preferably metal frame, and the center 5 is preferably glue frame.Specifically, at this In embodiment, optical diaphragm group 6 is also fitted on the light-emitting surface of the light guide plate 3, the optical diaphragm group 6 includes diffusion barrier 61 With brightness enhancement film 62.

In this way, by offering cutting line 21 in reflector plate 2, and cutting line 21 is allowed to correspond in adjacent LED42 Meta position installs, and on the one hand ensure on the corresponding position of the bottom surface of LED42, is extended with reflector plate 2, and reflector plate 2 exists It keeps complete on the corresponding position, so as to effectively provide light utilization, improves backlight illumination；On the other hand due to being equipped with Cutting line 21, i.e. reflector plate 2 separate on the centre position of adjacent LED42, cannot preserve in the horizontal continuously, thus The deformation of reflector plate 2 can be given to provide accommodation space, so that reflector plate 2 is not allowed on the position corresponding to LED42 Fold easily occurs, LED42 will not be influenced easily, effectively increase product quality.Preferably, the LED42 adjacent in every a pair Between all open up cutting line, so that prevent the effect of fold more preferable, product quality is more stable.

Specifically, in the present embodiment, as shown in figure 3, the cutting line 21 is close to 3 incidence surface side of the light guide plate Endpoint is located between 3 incidence surface of light-emitting surface and light guide plate of the LED42.It can effectively ensure that the reflecting effect of reflector plate 2, no Because of the setting of cutting line 21 reflecting effect of reflector plate 2 can be substantially reduced.Further, the cutting line 21 is close Lateral cutting line 22, the extending direction of the transverse direction cutting line 22 and institute are equipped at the endpoint of 3 incidence surface side of the light guide plate The extending direction for stating cutting line is vertical, and lateral cutting line 22, which is arranged, can further increase the deformation accommodation space of reflector plate, Improve product quality.Further, as shown in figure 4, reflector plate 2 is equipped with one on the position between LED42 and light guide plate 3 It towards the slope of light guide plate incidence surface, can be conducive to reflect into light in light guide plate 3 in this way, effectively improve light utilization Rate, and cut the line of rabbet joint 21 due to being equipped with, so that it is located at reflector plate 2 in larger, the Neng Goufang of flexibility close to LED location one end Slope is just set, production efficiency is improved.

The embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously Cannot it therefore be interpreted as the limitation to the utility model patent range, as long as using the form institute of equivalent substitution or equivalent transformation The technical solution of acquisition, shall fall within the scope of the present invention.
