Embodiment
Please refer to Fig. 1, the blooming piece that Fig. 1 illustrate is the first embodiment of the present invention.This blooming piece 100 comprise the UV cured glue-line 120 of a substrate material 110,, with a plurality of optics diffusion particles 130, wherein the material of substrate material 110 is consisted of transparent material, this material is for example polyethylene terephthalate (polyethylene terephthalate, PET), polypropylene (polypropylene, PP), triacetate fiber (triacetate cellulose, TAC) or polycarbonate (polycarbonate, PC).In addition, UV cured glue-line 120 is to be formed on substrate material 110, and the surface of this UV cured glue-line 120 is formed with a plurality of microstructures 122, and these microstructures 122 are to be arranged on the surface of UV cured glue-line 120 in random mode.In addition, these optics diffusion particles 130 are to be distributed in UV cured glue-line 120 in random mode.
In the present embodiment, the refractive index of described optics diffusion particle 130 is between 1.4 and 1.7.And, the mixture with respect to optics diffusion particle 130 with UV cured glue-line 120, the weight percent concentration of optics diffusion particle 130 is between 3% to 30%.That is to say, (quality of described optics diffusion particle 130)/(quality of the quality of described optics diffusion particle+this UV cured glue-line) is between 3% to 30%.
In addition, the material of optics diffusion particle 130 is to be mainly that material is formed by acryl, polymethylmethacrylate or polycarbonate, is consisted of.Purpleization line sclerosis glue is mainly comprised of oligomer (Oligomer), wherein still can be added with diluting monomer (monomer) and light initiator (Photo initiator) etc. to increase its character and reaction rate.The principal ingredient of purpleization line sclerosis glue used in the present invention is for example polyester acrylic oligomer (Polyester acrylic oligomer), epoxy acrylic oligomer (Epoxy acrylic oligomer) or polyurethane acrylic acid oligomer (Polyurethane acrylic oligomer).
Below, will the manufacturing process of blooming piece 100 be carried out to a brief introduction.Please also refer to Fig. 2 and Fig. 3, Fig. 2 is plotted as the process flow diagram of the blooming piece manufacture method of the first embodiment, the manufacturing equipment of the blooming piece that Fig. 3 illustrate is the present embodiment.First, execution step S110, provides a substrate material 110.As shown in Figure 3, substrate material 110 is to be discharged by a unlocking wheel 12, and moves forward by taking in the pulling force of wheel 20, auxiliary wheel 14, auxiliary wheel 18.Come, execution step S120, is coated on UV cured glue 120 ' on substrate material 110 again.As shown in Figure 3, UV cured glue 120 ' is to be stored in a container 11 originally, and it is the liquid with certain viscosity, and in UV cured glue 120 ', is distributed with a plurality of optics diffusion particles 130 as shown in Figure 1.Container 11 has a valve 81a.After valve 81a is opened, UV cured glue 120 ' just can be applied on substrate material 110 via valve 81a.
In addition, it should be noted that auxiliary wheel 14 with auxiliary wheel 18 except having the function that drives substrate material 110, also have the function supporting, to prevent that UV cured glue 120 ' on substrate material 110 is out of shape because weight itself produces.
Afterwards, execution step S130, by roller 15 roll extrusion on UV cured glue 120 '.On the surperficial 15a of this roller 15, there is an imprinted pattern (not illustrating), therefore, when roller 15 roll extrusion are crossed after UV cured glue 120 ', it is upper that the imprinted pattern on roller 15 just can be transferred to UV cured glue 120 ', and form a plurality of microstructures 122 on UV cured glue 120 '.Should be noted, the imprinted pattern on this roller 15 is the distribution that is random, therefore be also to distribute in random mode in the upper formed microstructure 122 of UV cured glue 120 '.
In step S140, it is upper that the light that light source 16a ~ 16d is sent is radiated at UV cured glue 120 ', so that the 120 ' sclerosis of UV cured glue.In the present embodiment, step S130 and step S140 are simultaneously.The light sending due to light source 16a ~ 16d is ultraviolet, thus can allow UV cured glue 120 ' produce sclerosis, to form a UV cured glue-line 120.
After UV cured glue 120 ' hardens completely, just carry out step S150, the UV cured glue after sclerosis 120 ' and substrate material 110 are taken in the lump.At this, the UV cured glue after sclerosis 120 ' and the zoarium of substrate material 110 are called to blooming master slice 100 '.Certainly, this area has knows that the knowledgeable also can take in product wheel 20 and change the product accommodation device that is designed to other kenels conventionally, as long as blooming master slice 100 ' can be taken in.Come again, carry out step S160, by being wound on product, taking in wheel 20 blooming master slice 100 ' and take off, and be divided into a plurality of blooming pieces 100 as shown in Figure 1.
Then, please refer to Fig. 4, the screen protector that Fig. 4 illustrate is the first embodiment of the present invention.This screen protector 200, except comprising the blooming piece 100 shown in Fig. 1, also comprises that an adhesion layer 210 and is from shape mould 220.Wherein, with respect to UV cured glue-line 120, adhesion layer 210 with from shape mould 220, are the other sides that are arranged at substrate material 110, and this adhesion layer 210 is at substrate material 110 and between shape mould 220.In the present embodiment; adhesion layer 210 is transparent material; when user's wish by screen protector 200 be attached to electronic installation (do not illustrate, as: in the time of on screen intelligent mobile phone), only need will tear and again screen protector 200 is attached on the screen of intelligent mobile phone from shape mould 220.
After test via inventor, find, after screen protector 200 is attached on the screen of electronic installation, the part that overall brightness reduces is to be less than known screen protector.And; may be due to the existence of microstructure 122 with optics diffusion particle 130; therefore can make the light that screen sends fully mix by the rear quilt of screen protector 200; therefore compared to known screen protector; screen protector 200 more can not allow user feel there is the existence of point-like particle after sticking, thereby improves user's impression in the use.
In addition, above-mentioned blooming piece 100 is except being applied in screen protector 200, and this area has knows that the knowledgeable also can be applied in them on other field conventionally.For example, also can be by blooming piece 100 diffuser plate for backlight module, to reach the effect that hides the flaw.
Above-described embodiment is only to give an example for convenience of description, though modified arbitrarily by person of ordinary skill in the field, all can not depart from as the scope of institute's wish protection in claims.
