Description
Technical field
The utility model relates to field of liquid crystal display, specifically relates to a kind of backlight module.
Background technology
Liquid crystal display obtains extensive use with its excellent quality, and liquid crystal itself is not luminous, needs backlight module to provide light source.Backlight module is mainly divided into straight-down negative and side entering type two kinds according to distribution of light sources position difference.What light source was conventional is CCFL light source and LED light source.LED light source, compared with CCFL light source, has energy-saving and environmental protection, the advantage such as frivolous, becomes main stream light sources now.Fig. 1 is the exploded view of direct-light type LED backlight module, and direct-light type LED backlight module generally includes glue frame 10, optical diaphragm group 20, diffuser plate 30, diffuser plate thimble, backboard 60 and LED lamp bar 50.Wherein LED lamp bar 50 is made up of light emitting diode (LED) 501 and circuit board (PCB/PWB).During backlight module assembling, be now placed on backboard 60 by LED lamp bar 50, reflector plate 40 covers in LED lamp bar 50, then places diffuser plate 30, optical diaphragm group 20 and glue frame 10 successively.Fig. 2 is that prior art LED lamp bar fixes schematic diagram, and LED lamp bar 50 is fixed on backboard 60, and by wire 80 conducting, wire 80 is fixed by fixation adhesive tape 70.If any one or more LED lamp bead breaks down in LED lamp bar, just a whole piece lamp bar must be changed, not only time-consuming the and cost of idleness of work consuming, and reduce production efficiency.
Utility model content
For solving the problem, the utility model provides a kind of backlight module, by arranging helicitic texture bottom LED lamp bead, backboard arranges the helicitic texture matched with LED lamp bead, when any one LED lamp bead breaks down, need not backlight module be dismantled, not need to change whole LED lamp bar, only need change the LED lamp bead of damage, time saving and energy saving.
The utility model provides a kind of backlight module, comprises a backboard and is fixed on the LED lamp bar on backboard.Wherein LED lamp bar comprises LED lamp bead and circuit board.Described backboard and circuit board are equipped with the perforate corresponding with LED lamp bead; Helicitic texture is provided with bottom described LED lamp bead; Described backboard is provided with the helicitic texture matched with LED lamp bead, and described LED lamp bead is sequentially fixed on backboard through described backboard and circuit board; Be provided with metallic gasket between described circuit board and LED lamp bead, realize the electrical connection between LED lamp bead and circuit board.
The utility model, by being provided with helicitic texture bottom LED lamp bead, is all provided with the perforate of corresponding LED lamp bead simultaneously on circuit board and backboard, solves backlight module and changes the loaded down with trivial details problem in lamp source.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
Fig. 3 is the utility model part-structure exploded view, as shown in Figure 3, the perforate 101 corresponding with LED lamp bead 200 is provided with bottom backboard 100, circuit board 90 is provided with the perforate 91 corresponding with LED lamp bead, helicitic texture 201 is provided with bottom LED lamp bead 200, backboard 100 is provided with the helicitic texture matched with the helicitic texture 201 of LED lamp bead 200, LED lamp bead 200 sequentially through the perforate 101 bottom backboard 100 and the perforate 91 on circuit board 90, is fixed on backboard 100 from the outside of backboard by helicitic texture 201.When having any one or more than one LED lamp bead breaks down, not needing whole backlight module to dismantle, not needing whole LED lamp bar to change, only need the LED lamp bead of damage is dismantled bottom backboard and changes, time saving and energy saving, enhance productivity.
Fig. 4 A is the utility model LED lamp bead front view, as shown in Figure 4 A, is provided with helicitic texture 201 bottom LED lamp bead 200, convenient installation or removal.Fig. 4 B is the utility model LED lamp bead top view.Fig. 4 C is the stereogram of the utility model LED lamp bead.
Fig. 5 is the utility model LED lamp bar schematic diagram, as shown in Figure 5, LED lamp bar comprises LED lamp bead 200 and circuit board 90, has metallic gasket (Pad), can realize the electrical connection between LED lamp bead 200 and circuit board 90 between LED lamp bead 200 and circuit board 90.
The utility model, by arranging helicitic texture bottom LED lamp bead, backboard arranges the helicitic texture matched with LED lamp bead, when any one LED lamp bead breaks down, backlight module need not be dismantled, do not need to change whole LED lamp bar, only need change the LED lamp bead of damage, time saving and energy saving.
