Specific implementation mode

To make the purpose of this utility model, technical solution and advantage are clearer, below in conjunction with the accompanying drawings to the utility model Embodiment is described in further detail.Obviously, described embodiment is a part of the embodiment of the utility model, rather than Whole embodiments.Based on described the embodiments of the present invention, those of ordinary skill in the art are without creative labor The every other embodiment obtained under the premise of dynamic, shall fall within the protection scope of the present invention.

Unless otherwise defined, the technical term or scientific terminology that the utility model uses are should be belonging to the utility model The ordinary meaning that the personage with general technical ability is understood in field." first " that is used in the utility model, " second " and Similar word is not offered as any sequence, quantity or importance, and is used only to distinguish different component parts.

As shown in Figs. 1-2, which show a kind of liquid crystal display die set provided by the utility model, the liquid crystal display die set packets Include back light unit 1, display panel 2 corresponding with the back light unit 1, the FPC3 being pressed on the display panel 2, support institute The metal end frame 4 of back light unit 1 and the main circuit board 5 set on 4 back side of the metal end frame are stated, the FPC3 is bent to the gold Belong between bottom frame 1 and the reflector plate 11 of the back light unit 1, the FPC3 is equipped with the first areas Lu Tong 31, the metal end frame 4 Equipped with lug boss corresponding with the areas 31 first Lu Tong 41.Specifically, in the present embodiment, the back light unit 1 further includes Light guide plate 12, optical diaphragm group 13 on the reflector plate 11, corresponding to the luminescence component of 11 incidence surface of light guide plate setting 14 support the center 15 of fixed function with rising.In this way, reflector plate 11 and metal end frame by the way that FPC3 to be extended to back light unit 1 Between 4, the effect of protection FPC3 can be effectively played, and by the way that lug boss 41, lug boss 41 are arranged directly on metal end frame 4 It corresponds to and contacts with the first areas Lu Tong 31 of FPC3, to realize the conducting of FPC3 and metal end frame 4, be conducive to Electro-static Driven Comb, no With the objects such as conducting resinl are added, production cost is saved, and since FPC3 is set between reflector plate 11 and metal end frame 4, i.e., The lug boss 41 of metal end frame 4 is towards 1 side of back light unit, in this way, not interfering with the main electricity set on 4 back side of the metal end frame The setting of road plate 5, simultaneously because the liquid crystal display die set being arranged so only need to be corresponding with the areas Lu Tong 31 by lug boss 41 when assembling , assembly process is saved, production efficiency is effectively increased.

Further, as shown in figure 3, in the present embodiment, the FPC3 is additionally provided with pair backwards to 4 side of the metal end frame It should be in the buffering foam 32 of 31 position of the first areas Lu Tong.Preferably, the buffering foam 32 is annular and reveals around described first The projected position in copper area 31 is arranged.In this way, since the presence of buffering foam 32 can effectively prevent metal end frame 4 or FPC3 to squeeze Damage the reflector plate 11 of back light unit 1, improve product quality, by make the buffering foam 32 around first area Lu Tong 31 Projected position is arranged, lug boss 41 when contacting the areas 31 the first Lu Tong when can make assembly, the first areas Lu Tong 31 relative to There are certain spaces for reflector plate 11, influence backlight effect without directly squeezing reflector plate 11.

Further, as shown in figure 4, the lug boss 41 be equipped with positioning region 411, the FPC3 be equipped with it is described fixed 411 corresponding location hole 33 of position portion, in this way, only can need to clearly determine location hole 33 and 411 correspondence of positioning region when assembly The relative position of FPC3 and metal end frame 4, it is convenient for assembly, improve efficiency of assembling.

Further, in the present embodiment, as shown in figure 5, the main circuit board 5 passes through viscose glue 6 and the metal end frame 4 It is fixedly connected, the main circuit board 5 is equipped with towards the second areas Lu Tong 51 of the metal end frame, and the metal end frame 4 is equipped with Shrapnel corresponding with the areas 51 second Lu Tong 42.In this way, metal end frame 4 by shrapnel 42 directly with main circuit board 5 second The areas Lu Tong 51 realize contact and conducting, facilitate Electro-static Driven Comb, do not have to the in addition elements such as setting conductive tape, effectively reduce production Cost and improve efficiency of assembling.Preferably, as shown in fig. 6, the quantity of the second dew copper 51 and shrapnel 42 is two.It is preferred that , insulating radiation layer is covered on the metal end frame 4, the position that the insulating radiation layer corresponds to the lug boss 41 is equipped with First windowing area, i.e. insulating radiation layer do not cover lug boss 41, do not influence the turn-on effect of lug boss 41, the insulating radiation layer It is equipped with the second windowing area corresponding to the position of the shrapnel 42, i.e. insulating radiation layer does not cover the shrapnel 42, do not influence shrapnel 42 turn-on effect.Covering insulating radiation layer can effectively improve the heat radiation function of metal end frame 4, specifically, the insulating radiation Layer can be the black ink layer for being dispersed with insulating radiation particle.

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.
