First panel 110 is bonding, and bonding strength is higher, and antistripping ability is stronger.
In an embodiment, as shown in figure 5, link block 150 further includes lower surface 151, the lower surface 151 of link block 150
Backlight module 130 is bonded by double-sided adhesive 104.Specifically, the lower surface 151 of link block 150 and second panel 120 are distinguished
It is adhered on double-sided adhesive 104.Wherein, double-sided adhesive 104 is, for example, the shading double faced adhesive tape with shade function.
In an embodiment, as shown in Figure 3 and Figure 5, link block 150 is located at the second panel side of second panel 120
Between 120a and the backlight module side 130a of backlight module 130, wherein between link block 150 and second panel side 120a
With distance P1, there is distance P2, and distance P1 is greater than distance P2 between link block 150 and backlight module side 130a.
Distance P1 is arranged between second panel 120 in link block 150 can be avoided link block 150 and second panel
120 frictions or the problems such as to 120 strike-through of second panel.
In an embodiment, link block 150 can be at least a side edging of backlight module 130, so that link block 150
Lower surface 151 and 152 area of attachment of upper surface maximize.As shown in fig. 6, link block 150 can be with the backlight of backlight module 130
Module side 130a edging.
Link block 150 of the invention can be solid block made of non-cohesive material, for example, by using PET
The materials such as (Polyethylene terephthalate), rubber are made.Link block 150 is using the figurate material system of tool
At, can cohesive force as needed determine the bond area of 150 upper and lower surface of link block, and then determine the size of link block 150,
The size of link block 150 can be also determined according to the airbreak area area of 140 one or both sides of flexible circuit board, not only shape it is carefully and neatly done and
And area of attachment is controllable, the situations such as avoids the occurrence of excessive glue, is uneven.In addition, the present invention is using the figurate material system of tool
Make link block 150, the effect trimmed with the side of backlight module 130 is more preferable.
As shown in fig. 6, link block 150 includes upper surface 152, in one embodiment, upper surface 152 can be pasted by setting
Layer 105 and be adhered in first panel 110.That is, adhered layer 105 can be according to the size of the upper surface 152 of link block 150
It carries out standby glue to be arranged, with material saving.
In other embodiments, as shown in Figure 7 and Figure 8, by being set between first panel 110 and second panel 120
Optical cement 102 keep the upper surface 152 of link block 150 and first panel 110 bonding.Specifically, optical cement 102 includes extremely
A few extension protrusion 102a extends protrusion 102a and extends to the top of link block 150, in this present embodiment, extends protrusion
102a covers the upper surface 152 of link block 150, to keep the upper surface 152 of link block 150 convex by the extension of optical cement 102
Portion 102a is adhered to first panel 110.
It please also refer to Fig. 3, Fig. 7 and Fig. 8, the two sides of optical cement 102, which are respectively provided with, extends protrusion 102a, sub- link block
150a, 150b pass through two extension protrusion 102a respectively and first panel 110 is bonding.The present embodiment for link block without shifting to an earlier date
Individually standby glue, simplifies processing step.Opposite, there is optical cement 102 a concave part 102b, concave part 102b to be located at soft
The top of circuit board 104 avoids flexible circuit board 104 and optical cement 102 bonding, influences its subsequent bending and installation.
In addition, link block of the invention can be the solid block that is formed after binder photocuring or heat cure.It please also refer to
Colloid point is placed in the region that backlight module 130 is not covered by flexible circuit board 140 by dispensing mode by Fig. 3 and Fig. 9,
Being exactly can be in the one or both sides dispensing of flexible circuit board 140.Later, first panel 110 is attached, first panel 110 and glue are made
Body is directly contacted and is bonded.The link block 150 ' for the solid block form that colloid is formed after photocuring or heat cure, at this point,
Link block 150 ' and first panel 110 and the bonding of backlight module 130 form a unified entirety.The present embodiment and Fig. 5 institute
Show that the difference of embodiment is that the form of link block is different.
It please also refer to Fig. 8 and Figure 10, in the present embodiment, optical cement 102 includes that at least one extends protrusion 102a, is prolonged
Protrusion 102a is stretched to extend to the top of link block 150 '.Since link block 150 ' itself has stickiness, can therefore increase and optics
The adhesion of the extension protrusion 102a of glue.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
It knows those skilled in the art and makes various corresponding changes and modifications, but these corresponding changes and change in accordance with the present invention
