It is able to be diffused as uniform area source in the point in backlight module or line source.In addition, in order to avoid using diffusion sheet and significantly
The briliancy of area source is reduced, brightness enhancement film generally can be also reconfigured between diffusion sheet, to improve the integral brightness of area source.
The structure of foregoing diffusion sheet is mostly with acryl, makrolon (PC) or the copolymer of acryl and styrene (MS)
The sheet-like structure formed etc. material, and there is certain light transmittance.In order to reach light source diffusion and uniform effect,
Typically can when it is made, add pigment and make into milkiness to be advantageous to the diffusion of light source and uniformly, or even can add again
It is small diffusion particle to enter many, and it is mainly by the setting of diffusion particle, to reach the purpose of light diffusion.
In transportation, because diffusion sheet is mostly plastics, diffusion sheet and light guide sheet or prismatic lens in backlight module
Between can all produce friction, phase mutual friction produces the sensitive components in damage by static electricity liquid crystal display, or even can be because electrostatic
Foreign matter is drawn onto in display face, causes scratch white point or the dirty phenomenon of foreign matter.For drawbacks described above, those skilled in the art
Need badly and a kind of antistatic diffusion sheet is provided, electrostatic caused by the material layer of diffusion sheet and adjacent contact can be enable slowly to release
Put, prevent electrostatic from being damaged to the component in liquid crystal display module.
Utility model content
The purpose of this utility model is to provide a kind of antistatic diffusion sheet, can make the material layer of diffusion sheet and adjacent contact
Caused electrostatic is slowly discharged, and prevents electrostatic from being damaged to the component in liquid crystal display module.
To achieve the above object, there is provided following technical scheme：The utility model provides a kind of antistatic diffusion sheet, including base
Material layer, diffusion layer and material layer, the diffusion layer are located at the upper surface of the substrate layer, the diffusion layer and material layer it
Between be sequentially provided with conductive adhesive layer and insulating barrier from the bottom up, the insulating barrier is provided with an opening, and the conductive adhesive layer is provided with
Stretched out with conductive strips from the opening and be provided with discharge band and outside gold with the material layer contacts, the end of the conductive adhesive layer
Belong to piece connection, the lower surface of the substrate layer is provided with anti-static coating.
Preferably, the conductive strips and discharge band are made up of flexible conducting material.
Preferably, the conductive strips and discharge band are worked out by some radial direction conductive filaments and broadwise conductive filament.
Preferably, the thickness of the anti-static coating is 0.1-1um.
Operation principle of the present utility model is：The utility model passes sequentially through conduction by conductive strips and material layer contacts
Glue-line and discharge band conduct frictional static to exterior metal sheets, avoid static focus；Backlight module in transportation,
Electrostatic caused by friction is slowly dissipated, and prevents component in backlight module from by damage by static electricity, improving product yield.
The utility model provides a kind of having the beneficial effect that for antistatic diffusion sheet：The utility model can prevent damage by static electricity from carrying on the back
Electronic component in optical mode group, prevent electronic component is wounded from causing to fail, while can also solve diffusion layer and material
Rubs mutually causes the phenomenon of Electrostatic Absorption foreign matter between layer.
