Embodiment
See also Fig. 2, shown in Figure 2 is the structure iron of adhesive tape of the present invention.As shown in the figure; This adhesive tape 100 is made up of two straton adhesive tapes; Wherein this first sub-adhesive tape 110 has first glue-line 103, second glue-line 104 and first substrate layer 101 and constitutes, and this first glue-line 103 and this second glue-line 104 are arranged at the both sides of first substrate layer 101 respectively; This adhesive tape 120 has the 3rd glue-line 105, the 4th glue-line 106 and second substrate layer 102 and constitutes, and the 3rd glue-line 105 and the 4th glue-line 106 are arranged at the both sides of second substrate layer 102 respectively, and wherein the 3rd glue-line 105 is connected with this second glue-line 104.The outside at this first glue-line 103 and the 4th glue-line 106 is respectively equipped with first release layer 107 and second release layer 108, and this first release layer 107 can be peeled off before this adhesive tape 100 uses with this second release layer 108.
Between this first sub-adhesive tape 110 and the second sub-adhesive tape 120; Also be provided with one deck layer of fibers 200; Specifically, this layer of fibers 200 is arranged on the one side of second glue-line, 104 adjacent the 3rd glue-lines 105, perhaps is arranged on the one side of the 3rd glue-line 105 adjacent second glue-lines 104.
Please in the lump referring to Fig. 3 A and Fig. 3 B, Fig. 3 A is the layer of fibers synoptic diagram of adhesive tape of the present invention, and Fig. 3 B is the layer of fibers sectional view of adhesive tape of the present invention.As shown in the figure, layer of fibers 200 is arranged on the 3rd glue-line 105, and it has one deck hairy fiber material 201, and it has implantation portion 202 and facies posterior hepatis 203.This layer fibrous matter 201 utilizes friction matching method (using hairbrush or swing roller towards the pre-determined direction friction), makes facies posterior hepatis 203 along first direction (like the direction of arrow among the figure) ordered arrangement.Like this, this implantation portion 202 is imbedded at the 3rd glue-line 105 inside, and this facies posterior hepatis 203 then drapes over one's shoulders the surface that is attached to the 3rd glue-line 105 along first direction.So, when this one side with layer of fibers 200 affacts on other viscous substances, tear along this first direction, this facies posterior hepatis 203 is difficult for being pulled up.Because this layer of fibers 200 is own inviscid; It is arranged on the viscosity that has reduced the 3rd glue-line 105 surfaces on the 3rd glue-line 105; And against this first direction or when other direction is torn; 203 of this facies posterior hepatises can be pulled up, and produce an extra resistance of pullling, thereby make that the 3rd glue-line 105 pasting effect are more obvious.Should be understood that when this layer of fibers 200 is not limited to be arranged on the 3rd glue-line 105, it is arranged on 104 last times of second glue-line, has identical effect.
See also Fig. 4 A-4B, Fig. 4 A is the design sketch when this first direction is torn the first sub-adhesive tape and the second sub-adhesive tape, and Fig. 4 B is the design sketch when tearing the first sub-adhesive tape and the second sub-adhesive tape against this first direction.As shown in the figure; The first sub-adhesive tape 110 along this first direction (as the diagram arrow shown in) when removing; These layer of fibers 200 basic no changes, its facies posterior hepatis 203 still drapes over one's shoulders the surface that is attached to the second sub-adhesive tape 120, but when this first sub-adhesive tape 110 removes against this first direction; Because the viscous force of this first sub-adhesive tape 110 itself; Pullled this facies posterior hepatis 203, made to produce a resistance of pullling between this first sub-adhesive tape 110 and the second sub-adhesive tape 120, thereby be not easy to remove this first sub-adhesive tape 110.
Please combine Fig. 2 in the lump referring to Fig. 5 A and Fig. 5 B, Fig. 5 A is the synoptic diagram of display unit of the present invention, and Fig. 5 B is the synoptic diagram of display unit of the present invention when removing.As shown in the figure, this display unit 300 has display panel 310, housing 320 and the adhesive tape 100 that is connected this display panel 310, housing 320.Wherein this display panel 310 has display area 312 and is positioned at this display area 312 non-display area 311 on every side, in this display area 312, is provided with first light polarizing film 313 and second light polarizing film 314.This housing 320 has fixed part 321, in order to this display panel 310 of fixed placement.This adhesive tape 100 is arranged in the non-display area 311 of this display panel 310.In the present embodiment; The first sub-adhesive tape 110 of this adhesive tape 100 is sticking obedient on display panel 310 through first glue-line 103; Its first substrate layer 101 is a light shield layer, is provided with the black macromolecular material in the one side of these first substrate layer, 101 adjacent first glue-lines 103, thereby can plays the effect of shading.The second sub-adhesive tape 120 of this adhesive tape 100 is sticking obedient on housing 320 through the 4th glue-line 106; Its second substrate layer 102 is the tamper; One side at these second substrate layer, 102 adjacent the 4th glue-lines 106 is provided with highly reflective material; The reflectivity of this highly reflective material is preferably between the 90%-95%, thereby can well reflect from the light such as back lighting device.
When this display unit 300 needs dismounting; Only need tear up along the layer of fibers direction of this adhesive tape; Because the resistance that produce between the first sub-adhesive tape 110 and the second sub-adhesive tape 120 this moment, much smaller than the intensity that can bear of panel week rafter, when making the sub-adhesive tape 110 of winning with second sub-adhesive tape 120 disengagings; Both can from housing, display panel be taken apart easily, and can not form damage by counter plate again.And; The thickness of this first sub-adhesive tape 110 is between the 0.01mm to 0.1mm, much smaller than the thickness of this second sub-adhesive tape 120, even do not remove the first sub-adhesive tape 110 during heavy industry; Can not bring too much influence yet, increase the yield of heavy industry greatly the thickness of this display unit.
By the detailed description of above preferable embodiment, hope can be known description characteristic of the present invention and spirit more, and is not to come claim scope of the present invention is limited with the above-mentioned preferable embodiment that is disclosed.On the contrary, its objective is that hope can contain in the scope of claim of being arranged in of various changes and tool equality institute of the present invention desire application.
