Next the structural form of diaphragm adhesive tape 300 is illustrated.
Figure 12 is the structural schematic diagram of diaphragm adhesive tape 300, and Figure 13 is the cuing open along diaphragm tape thickness direction of diaphragm adhesive tape 300
Face figure, Figure 14 are that liquid crystal display device removes the partial structure diagram after liquid crystal display panel 200, and Figure 15 is circled in Figure 14
Enlarged drawing.
As shown in Figure 12,14-15, whole diaphragm adhesive tape 300 is substantially in banded structure, including diaphragm adhesive tape ontology 310, is connected
It is connected to diaphragm adhesive tape ontology 310, pointed nose 320 and 330 positioned at both ends, and lacking on diaphragm adhesive tape ontology 310
Oral area 340, notch section 340 are used to avoid the protrusion 16313 on center, i.e. diaphragm adhesive tape 300 does not cover protrusion.Compared to center
163 other parts, the thinned degree of thickness caused by protrusion 16313 holds the top of diaphragm adhesive tape 300 is larger, therefore, when diaphragm glue
When band 300 does not cover protrusion 16313, diaphragm adhesive tape 300 is eliminated because thickness caused by protrusion is thinned.
Why pointed nose 302 and 303 is set as tip, is primarily to facilitate operator and shells from diaphragm adhesive tape supporting body
It is fixed at diaphragm hangers from diaphragm adhesive tape, and then by diaphragm adhesive tape.
As shown in figure 13, along the thickness direction of diaphragm, diaphragm adhesive tape 300 successively includes first base material 301, the first gum
302, the second substrate 303 and the second gum 304.
Compared to the second substrate 303, the compressibility with higher of first base material 301, compression ratio 40-60%, in the present invention
First base material 301 selects foam in embodiment, and the compression ratio of foam used is 50%.The compression ratio of second substrate 303 is 10%, phase
Than in first base material, the intensity of material therefor is big, hardness plays high rigidity filling function in 50-90 degree.Implement in the present invention
In example, the second substrate selects 70 degree of hardness of silica gel piece.
The first gum 302 in diaphragm adhesive tape 300 is located between first base material 301 and the second substrate 303, is used for first
Together with substrate 301 is adhesively fixed with the second substrate 303.Because only needing for the two to be adhesively fixed together, therefore the first gum 302
Adhesion strength is of less demanding, and adhesive tape can be used in the first gum 302.
As shown in connection with fig. 7, diaphragm adhesive tape 300 between liquid crystal display panel 200 and diaphragm hangers 152, lean on by first base material 301
Nearly liquid crystal display panel 200, it is 50% foam material that first base material, which selects compression ratio, is matched with the compression ratio of panel glue band 190.
In this way, the relatively high side of compression ratio is contacted with liquid crystal display panel 200 in diaphragm adhesive tape 300, prevent hardness excessive to liquid crystal display panel
200 damage, furthermore, the compression ratio of first base material 301 is suitable with the compression ratio of panel glue band, ensure that liquid crystal display panel 200
When thickness direction is squeezed, there is the deformation quantity being substantially the same, the edge of liquid crystal display device is relatively flat.
Compared to first base material 301, for the second substrate 303 at diaphragm hangers 152, the second gum 304 is bonded in second
Side of the substrate 303 far from the first gum 302, for being adhesively fixed entire diaphragm adhesive tape 300 in center 163.Compared to
First gum 302, the second gum has biggish adhesion strength, for diaphragm hangers to be securely adhesively fixed.In order to guarantee
Diaphragm hangers is adhesively fixed on center 163, the outer peripheral edge of diaphragm adhesive tape 300 is greater than the outer peripheral edge of diaphragm hangers 152, i.e.,
A part of diaphragm adhesive tape 300 is bonded on diaphragm supporting part 16312, bonds diaphragm hangers 152 and center admittedly to realize
It is scheduled on together, and then realizes being adhesively fixed for diaphragm.
Illustrate the diaphragm in the present invention to the fixed form of optical diaphragm below with reference to diaphragm adhesive tape in the prior art
The technical effect of adhesive tape.Figure 16-17 is the fixed form schematic diagram of optical diaphragm in the display device of the prior art, Figure 18 A-
18D is the procedure chart that diaphragm is jumped out in the display device of the prior art.
In the prior art, diaphragm adhesive tape 300' be with sticking foam, i.e., compared to diaphragm adhesive tape 300 of the invention,
Diaphragm adhesive tape 300' only includes first base material 301 interconnected and the second gum 304.
As can be seen that diaphragm adhesive tape 300' is whole substantially in banded structure from Figure 16-17 and Figure 18 A-18D, it is not present
Notch section 340, and the partial region of diaphragm adhesive tape 300' covers protrusion 16313.
As shown in Figure 18 A, when diaphragm hangers stress tilts, because diaphragm adhesive tape 300' is foam, there is relatively high pressure
Contracting, under stress effect, as shown in figure 18b, the thickness of diaphragm adhesive tape 300' can be thinned, when the thickness of diaphragm adhesive tape 300' subtracts
Gap between Bao Shi, diaphragm adhesive tape 300' and 16313 upper end of protrusion becomes larger, as a result, as shown in figure 18 c, diaphragm hangers 152
It one end then can be slowly by the gap between 16313 upper end diaphragm adhesive tape 300' and protrusion, over time, such as Figure 18 D
Shown, diaphragm hangers 152 falls off from protrusion 16313 with diaphragm adhesive tape 300', eventually leads to diaphragm and jumps out.
Compared with prior art, as shown in figure 19, the diaphragm adhesive tape 300 in the embodiment of the present invention because have two layers of substrate,
And the hardness of second layer substrate is larger, therefore, when the inclination of diaphragm hangers stress, compared to existing diaphragm adhesive tape, because of diaphragm
The hardness with higher of adhesive tape 300, under stress effect, the thickness of diaphragm adhesive tape 300 is thinned degree and hangs insufficient for diaphragm
One end of ear is by the gap between 16313 upper end of diaphragm adhesive tape 300 and protrusion, thus without causing diaphragm to be jumped out.
It should be noted that the diaphragm adhesive tape 300 in the embodiment of the present invention is applicable not only to straight-down negative display device, it is also suitable
It is use situation of the diaphragm adhesive tape 300'' in side entering type display device shown in Figure 20 in side entering type display device.
