200 include FPC (Flexible Printed Circuit, flexible PCB) and the lamp bead being arranged on FPC, wherein, FPC's
Covered with ink, Lu Tong areas are that part ink is removed so that a region of copper exposure in FPC surface on copper surface.So, from
Electrostatic derived from each blooming piece exports to the Lu Tong areas being connected with light-shielding conductive glue frame, and again by internal cabling most at last
Electrostatic exports from solder terminal.
It should be noted that backlight module also includes the structures such as glue frame support, what this was well known to those skilled in the art
Prior art, it will not be repeated here.
For example, as shown in figure 4, several blooming pieces 110 include a diffusion barrier 111 and a bright enhancement film 112, add lustre to
Film 112 is superimposed setting with diffusion barrier 111, the part of diffusion barrier 111 and 112 mutual stagger setting of bright enhancement film, diffusion barrier 111 and adds lustre to
The surface of film 112 is equipped with conductive layer.For example, as shown in Figure 5 and Figure 6, it is respectively the optical diaphragm group of another embodiment
The structural representation and partial enlarged drawing of part.Several blooming pieces 110 include a diffusion barrier 111 and two bright enhancement film 112A
And 112B, two bright enhancement film 112A and 112B superpositions are set together, and one of bright enhancement film 112B superpositions are arranged on diffusion
On film 111, the surface of each diffusion barrier 111 and bright enhancement film 112 is equipped with conductive layer.In another example several blooming pieces 110 wrap
Two diffusion barriers and a bright enhancement film are included, for bright enhancement film between two diffusion barriers, the surface of each diffusion barrier and bright enhancement film is equal
Provided with conductive layer.I.e. one of diffusion barrier, which staggers, to be stacked on the conductive layer of bright enhancement film, bright enhancement film stagger again be stacked in it is another
On the conductive layer of individual diffusion barrier.It should be noted that the type and quantity of blooming piece and mutual position relationship exist

Conductive layer at least partly expose；Light-shielding conductive glue frame is also connected with the conductive layer of light guide plate.For example, the surface of light guide plate applies
Conducting medium is covered to form conductive layer on the surface of light guide plate.In backlight module, light guide plate is mainly used in sending LED light source
Light showed in the form of area source.So, by setting conductive layer on the surface of light guide plate, avoid blooming piece and lead
Because electrostatic be present so as to produce Electrostatic Absorption between tabula rasa, and then produce shade and to cause liquid crystal display device to show bad.
For example, backlight module also includes reflector plate, the surface of reflector plate is provided with conductive layer, and light guide plate superposition is arranged on reflection
On piece, reflector plate at least part and light guide plate and the mutual stagger setting of each blooming piece, so that the conductive layer of reflector plate is at least
Part exposure；Light-shielding conductive glue frame is also connected with the conductive layer of reflector plate.Reflector plate is used in the light that reflex LED light source is sent
Not towards the part in display panel direction, to improve the utilization ratio of LED light source.It is situated between for example, the surface coating of reflector plate is conductive
Matter is with the surface of reflector plate formation conductive layer.So, by setting conductive layer on the surface of reflector plate, light guide plate and anti-is avoided
Penetrate because electrostatic be present so as to produce Electrostatic Absorption between piece, and then produce shade and to cause liquid crystal display device to show bad.
A kind of liquid crystal display device is also disclosed in another embodiment of the utility model.For example, a kind of liquid crystal display device, bag
Include：Backlight module described in liquid crystal panel and as above any embodiment, liquid crystal panel include down polaroid, under liquid crystal panel
Polaroid abuts with light-shielding conductive glue frame.It should be noted that liquid crystal panel generally include to be sequentially overlapped the upper polaroid of setting,
Top glass substrate, lower glass substrate and down polaroid, this be those skilled in the art can known to prior art, herein no longer
Repeat.
Above-mentioned liquid crystal display device, because the electrostatic between the blooming piece in the backlight module of liquid crystal display device is final
Be exported, avoid and Electrostatic Absorption is produced because electrostatic be present between each blooming piece, so avoid therefore produce shade and
Liquid crystal display device is caused to show that bad situation occurs.
In order to further avoid producing shade in liquid crystal panel between all parts because of Electrostatic Absorption, for example, liquid crystal surface
The surface of the down polaroid of plate is provided with conductive layer, and the conductive layer of down polaroid abuts with light-shielding conductive glue frame.For example, liquid crystal panel
Down polaroid bottom surface coating conducting medium with the bottom surface of the down polaroid of liquid crystal panel formed conductive layer.So, by liquid
The electrostatic of the down polaroid of crystal panel also exports, after avoiding liquid crystal panel and backlight module assembling, liquid crystal panel and backlight mould
Electrostatic Absorption is produced between group because electrostatic be present, and then avoids therefore produces shade and to cause liquid crystal display device to show bad
Situation occur.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
