Specific embodiment
Hereinafter multiple implementation methods of the invention, as clearly stated, the details in many practices will be disclosed with schema
Will be explained in the following description.It should be appreciated, however, that the details in these practices is not applied to limit the present invention.Also
It is to say, in some embodiments of the present invention, the details in these practices is non-essential.Additionally, for the sake of simplifying schema, one
A little existing usual structures will be illustrated in the way of simple signal in the drawings with element.
Refer to Fig. 1, Fig. 1 is that the compound adhesive tape of body embodiment of the present invention is coated on the schematic side view of display module.This
Example is a kind of compound adhesive tape 10 that may be used to coat display module 20.Display module 20 includes display panel 202 and framework
204, display panel 202 for example, liquid crystal display panel, organic electroluminescence display panel or electronic paper panel, but it is not subject to the limits.It is multiple
Rubber alloy band 10 is coated and fixed display panel 202 and framework 204, comprising the first adhesive tape 102 and the second adhesive tape 104.First adhesive tape 102
Comprising relative first surface 1021 and second surface 1022.The bending of first adhesive tape 102 is attached at display module 20, wherein second
Surface 1022 sticks in upper surface 203 and the side surface 205 of display module 20.The bending of second adhesive tape 104 is attached at display module
20, wherein the second adhesive tape 104 is local to be attached at the first adhesive tape 102 and the local lower surface 207 for being attached at display module 20.
The thickness of the first adhesive tape 102 is more than the second adhesive tape 104 in the present embodiment.Due to display module in narrow frame framework
Non-display area is narrower, and with larger thickness, preferable first adhesive tape 102 of stickiness can have preferably glutinous in less pasting on area
Though effect be not easy warpage or depart from display module 20 upper surface 203.Separately, the first adhesive tape 102 is only attached at aobvious after bending
Show the side surface 205 of module 20, no longer attach to the lower surface 207 of display module 20, but in addition by thickness less second
Adhesive tape 104 to be sticked in bend again after the first surface 1201 of the first adhesive tape and pasted to lower surface 207.This kind of implementation method can be simultaneously
Ensure that the first adhesive tape 102 will not depart from transport or subsequent installation in the case of side area of attachment deficiency in thinning machine
The side surface 205 of display module 20, and it is smaller due to being pasted to the thickness of the second adhesive tape 104 of the lower surface 207 of display module 20,
Integral thickness thus can be reduced simultaneously in good cemented effect.And because the second adhesive tape 104 has less thickness, to whole
The influence of body thickness is relatively low, thus with the first adhesive tape in the upper surface 203 of display module 20 stick length L2 compared with, the second adhesive tape
Can be more long in the length L3 that sticks of the lower surface 207 of display module 20.
In an embodiment, the ratio of the thickness of the first adhesive tape 102 and the second adhesive tape 104 can be more than 2, and this configuration mode can
There is less module thickness simultaneously with preferable cemented effect.In a specific embodiment, the thickness of the first adhesive tape 102 is
0.06mm, the thickness of the second adhesive tape 104 is 0.01mm.
In an embodiment, the first adhesive tape 102 can be comprising at least two metal layers, and this kind of adhesive tape is less susceptible to multiple after bending
Position, thus less easily warpage departs from display module 20.One layer of the two metal layers wherein at least of the first adhesive tape 102 can be aluminium
Layer, and for example can be double aluminium glue bands.
First adhesive tape 1021 has the first ora terminalis 1023 of the side surface 205 positioned at display module 20, and the second adhesive tape 104 has
There is the second ora terminalis 1043 of the first surface 1021 positioned at the first adhesive tape 102.Ideally the first ora terminalis 1023 and side surface
205 root edges are trimmed, that is, are trimmed with the intersection of lower surface 207 with side surface 205；Second ora terminalis 1043 and side surface 205
Apical margin is trimmed, that is, is trimmed with the intersection of upper surface 203 with side surface 205.Now the first adhesive tape 102 can and display module
20 area of attachment for having maximum, the second adhesive tape 104 can have the area of attachment of maximum with the first adhesive tape 102.Simultaneously because the first glue
With 102 and the non-bulging root edge and apical margin in side surface 205 of the second adhesive tape 104, without increasing module thickness.But consider to make
Precision problem when tolerance is with man-made assembly, the first ora terminalis 1023 can be backed out somewhat in the segment distance of 205 root edge of side surface one, second
Ora terminalis 1043 can be backed out somewhat in the segment distance of 205 apical margin of side surface one.In other words, the first adhesive tape 102 and the weight of the second adhesive tape 104
The length L1 of folded part can be less than or equal to the height H of the side surface 205 of display module 20.It is noted that side described herein
The height H of surface 205 is distance of the apical margin of side surface 205 to root edge, and the measurement direction of length L1 is big with the measurement direction of height H
It is identical in cause.
Fig. 2 is refer to, Fig. 2 is the schematic side view of a specific embodiment of the invention.Display panel 202 is in the present embodiment
Liquid crystal panel, comprising upper substrate 2021 and infrabasal plate 2022, and be attached at respectively the upper polaroid 2023 of upper substrate 2021 with
Down polaroid 2024.Framework 204 can include glue frame 2043 and metal frame 2045, but not subject to the limits, in other embodiments middle frame
204 are alternatively integrally formed single framework.Back light unit can be equiped between display panel 202 and framework 204, be only painted herein
Show light guide plate 2041 as signal.Upper polaroid 2023 is pasted to the edge of display panel 2021 in the present embodiment, therefore pastes
The first adhesive tape 102 in the upper surface of display module 20 is the outer surface for being attached at upper polaroid 2021.
Fig. 3 is refer to, Fig. 3 is the schematic side view of another specific embodiment of the present invention.The present embodiment framework is implemented with Fig. 2
Example is similar, and difference is not only pasted to the edge of upper substrate 2021 of display panel in the upper polaroid 2023 of the present embodiment.This feelings
Under condition, the first adhesive tape 102 is not preferably overlap with upper polaroid 2023, that is to say, that stick in the of display module upper surface 203
One adhesive tape is the outer surface of the upper substrate 2021 for being attached at display panel 202.Due to the first adhesive tape 102 with upper polaroid 2023 not
Overlap, integral module thickness can be made relatively low.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Knowing those skilled in the art can make various corresponding changes and deformation, but these corresponding changes and deformation according to the present invention
The protection domain of the claims in the present invention should all be belonged to.
