0.7mm, 0.8mm or 0.9mm.In the thickness range, the reliable adhesion between cover plate 30 and substrate 10, and energy had both been can ensure that
Prevent tree lace 60 to be diffused into outside substrate 10, or the exterior domain on the gluing road of substrate 10 is polluted because of the diffusion of tree lace 60.
In certain embodiments, glue end 62 can be end points, as shown in Figure 5 and Figure 6, such as starting point for dispensing glue or end
Point.In further embodiments, glue end 62 can also be one section of tree lace with certain length, as shown in fig. 7, Fig. 7 is this
Invent the side structure schematic diagram that another embodiment forms tree lace on substrate after step s 102, the length of glue end 62 can be with
It is 4-6mm, such as 4.5mm, 5mm or 5.5mm etc..
If the distance at glue end 62 to the edge of substrate 10 is too small, tree lace 60 is pressurized after diffusion, in the length side of tree lace 60
Readily diffuse into outside substrate 10 upwards, if the distance at glue end 62 to the edge of substrate 10 is excessive, substrate 10 and cover plate 30
Easily ftractureed in the edge of substrate 10, make the adhesion between substrate 10 and cover plate 30 insecure so that display module is integrally tied
Structure built on the sand, thus is difficult to form the protection to substrate 10.In order to prevent above mentioned problem from producing, the present embodiment arrives glue end 62
The distance at the edge of substrate 10 is set to 0.2-0.5mm, for example, 0.3mm, or 0.4mm.Within the range, glue can not only be prevented
Line 60 spreads and spills into outside substrate 10, moreover it is possible to ensure the reliable adhesion of substrate 10 and cover plate 30, so as to prevent substrate 10 from breaking
Split, preferably protective substrate 10.
Specifically, in step S102, dispensing is carried out to form tree lace 60 according to default Jiao Lu on second area 14, and
Make the thickness of glue end 62 has various not less than the mode of the thickness of extension 64.
For example, in one embodiment, translational speed ratio of the Glue dripping head when glue end 62 is formed is forming extension
Translational speed during portion 64 is slow, so that there is more colloids to be put on glue end 62 so that the thickness of glue end 62 is more than
Or equal to the thickness of extension 64.
Specifically, in the present embodiment, Glue dripping head is not more than Glue dripping head and is being formed in the translational speed for forming glue end 62
The 1/2 of the translational speed of extension 64.For example, when glue end 62 is formed, the translational speed of Glue dripping head is to form extension 64
Translational speed 1/3 or 1/4 etc..
In another embodiment, Glue dripping head can also pause special time when glue end 62 is formed, and make enough glue
Body point on the glue end 62 after move again and form extension 64, or, Glue dripping head is after at the uniform velocity movement forms extension 64,
Stop dispensing again after forming pause special time at the position of glue end and making enough colloid points on the glue end 62, so that
So that thickness of the thickness of glue end 62 more than or equal to extension 64.
In one embodiment, the time that Glue dripping head pauses when glue end 62 is formed is 1-1.5s, for example, 1.2s,
1.3s or 1.4s.

After on plate 10, the gel quantity in the Glue dripping head unit interval is turned down, Glue dripping head is moved and is formed extension 64.
Specifically, gel quantity of the Glue dripping head in the unit interval at glue end 62 can be that Glue dripping head is forming extension
1.5-2.5 times of the gel quantity in unit interval when 64.For example, 1.7 times, 2 times or 2.2 times.
Wherein, the adjustment of the size of the gel quantity in the unit interval can be in several ways.
For example, in one embodiment, can be by setting valve in Glue dripping head, by the size for adjusting valve
To control the gel quantity in the unit interval, for example, Glue dripping head is opened greatly valve, so that more colloids when glue end 62 is formed
Sprayed from Glue dripping head.And Glue dripping head turns down valve, so as to reduce the plastic emitting in the unit interval when extension 64 is formed
Amount.
In another embodiment, the plastic emitting in the unit interval can be adjusted by adjusting the plastic emitting speed of Glue dripping head
Amount, in Glue dripping head when glue end 62 is formed, colloid pressure in increase spot gluing equipment so that colloid quickly sprays from Glue dripping head
Go out, and when Glue dripping head is when extension 64 is formed, reduce colloid pressure in spot gluing equipment so that Glue dripping head sprays colloid
Speed slows down.
