Description
Technical field
The utility model belongs to technical field of liquid crystal display equipment, specifically a kind of multifunctional optical polyester film.
Background technology
Backlight module（Backlight Module）For Thin Film Transistor-LCD（Thin Film Transistor
Liquid Crystal Display, abbreviation TFT-LCD）Light emitting source, with optical thin film, light guide plate, CCFL group,
Or the composition such as LED light bar, backboard and frame of plastic.Because liquid crystal does not light in itself, show in order to which user can be clearly seen on LCD
The content shown, a backlight module that can project light source must be added at the LCD back sides, after light is passed through LCD, information is passed
It is delivered in the eye of user, therefore backlight module is one of LCD (key part and component).Backlight module is more than liquid crystal display
Light source, also influence LCD briliancy, the uniformity, picture taste and visual angle.
The main member of backlight module system includes：Light source, light guide plate, all kinds of blooming pieces.Wherein light source mainly have EL,
CCFL and LED three types, two kinds of side-light type and straight-down negative can be divided into according to distribution of light sources position difference.With LCD modules
Constantly develop to brighter, lighter, thinner direction, side-light type CCFL backlight turns into the main flow of current backlight development.Optics
Diaphragm mainly includes reflectance coating, diffusion barrier and brightness enhancement film.The main function of reflectance coating is the reflectivity for improving optical surface, will be leaked
Go out the light high efficiency of light guide plate bottom and reflect without loss, so as to reduce light consume, reduce power consumption, improve liquid crystal display
The light saturation degree of device.
In addition, it is necessary to which spot light or line source are atomized into uniform area source in LCD backlight module.Cause
This, reflectance coating not only needs very high reflectivity, also as far as possible to reflect away incident ray in the form of irreflexive, with
Improve the briliancy of panel of LCD and control the uniform of brightness.This requires reflectance coating surface that there is certain light diffusion to make
With.
Need to carry out punch forming to film in road process after reality, due to having the presence of reflecting layer particle, meeting
Produce many chip dust, it is therefore desirable to there is certain antistatic property on the surface of film, prevent adsorbing powder dust in table
Face.
Utility model content
The technical problems to be solved in the utility model is：In order to solve existing backlight film during punch forming, by
In the presence for having reflecting layer particle, many chip dust can be produced, are adsorbed on polyester film the problem of, the utility model provides
A kind of multifunctional optical polyester film, reflecting layer are to carry out melting extrusion by biaxial tension extruder, are applied in its upper surface
The antistatic diffusion layer of cloth, chip adsorbing powder dust is not only solved in backlight film the problem of, and obtained optical polyester film
Light diffusing it is more preferable.
Technical scheme is used by the utility model solves its technical problem：A kind of multifunctional optical polyester film, bag
Include：The reflecting layer at middle part, the antistatic diffusion layer on the upside of reflecting layer and the brightness enhancement layer on the downside of reflecting layer, the blast
Layer is some triangular prisms composition being set up in parallel in the same direction, and the brightness enhancement layer downside is coated with antistatic coating.
In order that diffusion layer both can guarantee that good light diffusion, moreover it is possible to make following process process polyester film surface not
Attracting debris dust, the antistatic diffusion layer are PMMA/SiO2Composite Nano antistatic coating.Wherein, PMMA/SiO2It is compound
Nano-anti static coating can select commercially available prod, can also make by oneself, be prepared in the utility model using prior art.
Specifically, above-mentioned PMMA/SiO2The coating weight of composite Nano antistatic coating is 15-25 g/m2。
In order to ensure the light transmittance of polyester film, SiO is stated2Particle diameter be 60-120nm.
Specifically, above-mentioned triangular prism is regular triangular prism.The angle distribution of light can be improved, will be projected equably from diffusion sheet
The light dissipated to all angles is converged on axial angle, that is, in positive angle, is not increasing the feelings of outgoing total light flux
Axial brightness is improved under condition.
Specifically, above-mentioned brightness enhancement layer thickness is 10-13 μm.
Specifically, above-mentioned antistatic coating coating weight is 30-40 g/m2.Wherein antistatic coating can be PMMA/SiO2
The antistatic coating that composite Nano antistatic coating or the coating of universal antistatic coating form.
The beneficial effects of the utility model are：
A kind of multifunctional optical polyester film provided by the utility model, reflecting layer are carried out by biaxial tension extruder
Melting extrusion, antistatic diffusion layer is coated with its upper surface, not only solves chip adsorbing powder dust in backlight film the problem of, and
And the light diffusing of obtained optical polyester film is more preferable.
A kind of multifunctional optical polyester film provided by the utility model, antistatic diffusion layer select PMMA/SiO2It is compound
Nano-anti static coating both can guarantee that good light diffusion, moreover it is possible to following process process polyester film surface is not adsorbed broken
Consider dust to be worth doing.
A kind of multifunctional optical polyester film provided by the utility model, the antistatic painting of coating setting on the downside of brightness enhancement layer
Layer, on the one hand can ensure the antistatic property of polyester film, on the other hand can effectively protect brightness enhancement layer.
