The utility model discloses change traditional diffuser plate particle layer and microstructured layer integrated into one piece's structure, adopted the compound mode of multilayer to improve the light dispersion performance of diffuser plate greatly to prevent between diffusing particle layer and the microstructured layer to take place the problem that breaks away from because of the equal reason of coefficient of expansion through setting up the buffer layer.
Description
Technical field
This utility model relates to processing of high molecular material and applied technical field, particularly relates to a kind of multiplelayer microstructure light and expands
Fall apart.
Background technology
Light diffusing sheet, also known as even tabula rasa, expands tabula rasa, has high light diffusing, high transmission rate and can block light source well
Etc. feature, it is LED illumination and the important parts of flat display field.Light diffusing sheet can play the effect of shading, it is possible to resistance
Be in the light passes through, and generally, the light diffusing of light diffusing sheet is the best, and light transmittance is the lowest.
Generally, diffuser plate includes diffusion particle layer and is arranged at the refraction structure above diffusion particle layer, the two superposition
Forming monolayer diffuser plate, current diffuser plate mostly is monolayer diffuser plate, the masterbatch mostly phase of diffusion particle layer and refraction structure layer
With, and refraction structure mostly is the single shapes such as V-type groove, U-shaped tongue, uses this kind of diffuser plate to only complete One Diffusion Process, not
Light being carried out multi-level diffusion, causes light after diffuser plate spreads, visual angle is too small, affects the effect of light projection simultaneously
Really.Meanwhile, the light transmittance of single refraction structure light effect relatively low, even is poor.
Utility model content
In order to solve above-mentioned technical problem, it is provided that the light diffusing sheet that a kind of refraction structure light effect diversified, even is good, this reality
By novel offer techniques below scheme:
A kind of multiplelayer microstructure light diffusing sheet, spreads basic unit including at least two-layer；Described diffusion basic unit by diffusion particle layer,
Cushion and microstructured layers are constituted；Described diffusion particle layer, cushion and microstructured layers are by hot-forming connection；Described
Diffusion particle layer is PS layer, and described microstructured layers is PC layer, and described cushion is POE layer；The micro structure of described diffusion basic unit is mutual
Differ.
PS material has the advantage that density is little, light transmittance is high, and PC material then has that fire resistance is good, fatigability is bought in impact resistance
The advantage that energy is good, combines both materials, it is possible to improve the mechanicalness of entirety while ensureing diffuser plate optical property
Energy and fire resistance；Owing to PS material is inconsistent with PC material thermal expansion coefficient, therefore cushion is set, it is possible to after preventing from being heated
Diffusion particle layer departs from microstructured layers junction.
Further, spread basic unit including two-layer, be respectively diffusion basic unit one and diffusion basic unit two；Described diffusion basic unit one
Including diffusion particle layer one, cushion one and microstructured layers one；Described diffusion basic unit two includes diffusion particle layer two, cushion two
With microstructured layers two；Wherein microstructured layers one is the semielliptical shape bump structure of closely arrangement；Microstructured layers two is big triangular prism
The structure staggered with little triangular prism, the top of described big triangular prism is corresponding with the position, junction of adjacent two row salient points.
The combination of both micro structures can improve single refractive Iy, improves diffusion effect and relative haze.
Further, it is provided with fluorescent labeling one, described diffusion base between the adjacent two row salient points of described diffusion basic unit one
The big triangular prism top of layer two is provided with fluorescent labeling two.In process of production will diffusion basic unit one and diffusion basic unit two compound tense
Only fluorescent labeling need to can be made to manifest with ultra violet lamp, can be used as the datum line of compound suppressing.
The beneficial effects of the utility model are: change conventional diffusion plate particle layer and the integrated knot of microstructured layers
Structure, uses the mode of MULTILAYER COMPOSITE to substantially increase the light dispersive property of diffuser plate, and prevents from spreading grain by arranging cushion
The problem occurring to depart from because of the not equal reason of the coefficient of expansion between sublayer and microstructured layers.
