Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Consult Fig. 2, Fig. 3, the utility model tool hides the first embodiment of flaw blooming, hide flaw optical film and comprise a substrate 6 and multiple triangular prism post 7, and in the present embodiment, this substrate 6 and described triangular prism post 7 can be integral structure or non-Unitary structure.
This substrate 6 comprises contrary incidence surface 61 and the exiting surface 62 arranged, can by polyethylene terephthalate (polyethylene terephthalate, referred to as PET), PEN (polyethylene naphthalate, referred to as PEN), polycarbonate (polycarbonate, referred to as PC) etc. flexible transparent material make, but not to be limited with previous materials.
Described triangular prism post 7 is made by ultraviolet light photopolymerization transparent resin, be arranged at the exiting surface 62 of this substrate 6 each other abreast, each triangular prism post 7 comprises first inclined-plane 71, being tilted to extend by this exiting surface 62 and is tilted to extend by this exiting surface 62 and be connected on second inclined-plane 72 on this first inclined-plane 71, and one coordinates with this second inclined-plane 72 angle theta defined by this first inclined-plane 71.The angle theta of described triangular prism post 7 respectively divides into one first angle district θ
1and one second angle district θ
2, respectively this first angle district θ
1to be coordinated with the normal L of this exiting surface 62 by each this first inclined-plane 71 and define, and this first angle district θ in the present embodiment
1angle be not more than 50 degree and be not less than 10 degree.This second angle district θ
2to be coordinated with the normal L of this exiting surface 62 by each this second inclined-plane 72 and define, and its angle θ
2differ from respectively this first angle district θ
1, each this second angle district θ in the present embodiment
2angle be not more than 50 degree and be not less than 10 degree.Therefore, according to the enforcement aspect on above-mentioned the first inclined-plane 72, inclined-plane 71, second about triangular prism post 7, the cross section of the present embodiment intermediate cam prism columns 7 can form the non-isosceles triangle as Fig. 3, and each triangular prism post 7 can have identical cross sectional shape, or also can have different cross sectional shapes as required and each other, and not be limited with particular implementation.
In addition, respectively this first inclined-plane 71 of this triangular prism post 7 is rough surface with this second inclined-plane 72, and its surfaceness is between 0.1 μm to 5 μm.Accordingly, the anaclasis characteristic of the rough surface adjustable triangular prism post 7 on the first inclined-plane 72, inclined-plane 71, second, make tool hide flaw blooming and not easily produce the problems such as folded line, excreting dampness, and make the defect of substrate 6, triangular prism post 7, damage not easily discovered, and promotes its optical appearance.What illustrate is, depending on actual needs, tool hides flaw blooming except all being formed except the enforcement aspect of rough surface on the first inclined-plane 72, inclined-plane 71, second, also the wherein one only on the first inclined-plane 72, inclined-plane 71, second can form rough surface, so also can reach the purpose of this utility model.
Consult Fig. 4, for the utility model tool hides the second embodiment of flaw blooming, the tool screening flaw blooming of the present embodiment is roughly the same with the first embodiment, comprise a substrate 6 and multiple triangular prism post 7, and this substrate 6 and described triangular prism post 7 can be integral structure or non-Unitary structure.But, the essential difference of the present embodiment and the first embodiment is, in first embodiment, the incidence surface 61 of substrate 6 is smooth planar surface, in the present embodiment, the incidence surface 61 of substrate 6 forms rough surface, screening flaw blooming like this can promote its optical appearance by the rough surface of incidence surface 61 further, slows down the harmful effect that the problems such as folded line, excreting dampness, structural damage cause display effect.
Consult Fig. 5, for the utility model tool hides the 3rd embodiment of flaw blooming, it is roughly the same with the second embodiment that this tool hides flaw blooming, also comprises a substrate 6 and multiple triangular prism post 7.But, in aforementioned two embodiments, first inclined-plane 71 of each triangular prism post 7 is the depression forming tip-angled shape with the second inclined-plane 72 of adjacent triangular prism post 72, but in the present embodiment, the first inclined-plane 71 of each triangular prism post 7 and 72, second inclined-plane of adjacent triangular prism post 7 form the depression of arc angle shape, so also can reach the purpose of this utility model.
In sum, the utility model tool hides flaw blooming and provides spotlight effect by the triangular prism post 7 that cross sectional shape is non-isosceles triangle, and this first inclined-plane 71 of each triangular prism post 7, this second inclined-plane 72 forms rough surface, structural damage can be solved easily discovered or folded line, the problem that the optical phenomenas such as excreting dampness cause, so can replace by simple layer blooming the stack architecture that the diffusion sheet of existing side light type back light module and prismatic lens form, this backlight module is made to reach slimming, thus increase assembling yield and reduce costs expenditure, so really can the purpose of this utility model be reached.
