Abstract
The invention provides a method for bonding of a touch screen and a mask plate used by the method. The method comprises the following steps of covering the surface of a first substrate with a mask plate, uniformly coating the mask plate and the first substrate with an aqueous binder so that the aqueous binder layers covering the mask plate and the first substrate are formed, removing the mask plate so that aqueous binder patterns corresponding to hollow patterns of the mask plate are formed on the surface of the first substrate, exposing the aqueous binder patterns so that the aqueous binder is cured to form binder patterns, overlaying a second substrate onto the first substrate in first time after aqueous binder pattern exposure, and carrying out lamination so that the first substrate and the second substrate are bonded by the binder patterns. Through the good fluidity of the aqueous binder, a uniform and thin bonding layer is formed so that bubbles caused by uneven local thickness of the bonding layer are avoided and bonding quality and light transmittance are improved.

Specific embodiment
The flow chart of the touch screen applying method that Fig. 1 is provided for one embodiment of the invention；As shown in figure 1, the present invention is provided
A kind of touch screen applying method, including：
Step 101, mask plate is covered on the surface of first substrate, and the even spread aqueouss bonding on mask plate
Agent, to form the aqueous binders layer being covered on mask plate and first substrate.
As shown in Fig. 2 by 21 horizontal positioned bench top of first substrate to be fit, then mask plate 3 can be put
The surface upward of first substrate 21 is put, there is wherein on mask plate 3 pierced pattern 30 so that 21 surface of first substrate is to should
Expose the part of pierced pattern；Aqueous adhesive layer is uniformly coated on mask plate 3 and the first base by the instruments such as later use brush
The position of the correspondence pierced pattern of plate 21, is covered in mask plate 3 and first substrate 21 by the pierced pattern on mask plate 3 so as to be formed
The aqueous adhesive layer of the upper for exposing.
Step 102, aforementioned mask plate is removed, make to stay on the surface of first substrate and match with the pierced pattern on mask plate
Aqueous binders pattern 23（As shown in Figure 3）；That is, Fig. 2 and Fig. 3 is refer to, due to the effect of blocking of mask plate 3 so that the
Aqueous binders are also left in the position that the pierced pattern 30 on mask plate 3 is only corresponded on one substrate surface, and the aqueouss for staying are viscous
The pattern that knot agent is surrounded just is matched with the pierced pattern on mask plate 3.
Step 103, aqueous binders pattern is exposed, makes aqueous binders solidify to form colloidality adhesive pattern.
Specifically, the parameters such as the adopted light type of exposure, and time of exposure can be according to concrete aqueous binders
To determine, i.e., by certain types of light（For example, ultraviolet, infrared ray etc.）After irradiating the aqueous binders certain hour,
Which can be made by the gluey state that good fluidity, watery State Transferring is semi-solid preparation.Also, the glue formed after exposed
The shape of property adhesive pattern is not changed in compared with the aqueous binders pattern before exposure, and only its mobility is decreased obviously, just
In follow-up laminating operation.
Step 104, in the very first time after to aqueous binders pattern exposure, second substrate is stacked and placed on into above-mentioned first
On substrate, and pressed, first substrate and second substrate to be bonded together by colloidality adhesive pattern.
As shown in figure 4, second substrate 22 can be stacked and placed on side table of the first substrate 21 with colloidality adhesive pattern
On face, it is then possible to pressure roller is utilized from 21 opposite side surface roll-in of first substrate, so that first substrate 21 and second substrate 22
Reliably it is adhesively fixed together by the colloidality adhesive pattern.
It should be noted that first substrate and second substrate in the present embodiment can in touch screen as specific function
The glass plate of layer, nesa coating etc.；Also, the pierced pattern on mask plate determines the colloidality bonding agent figure for ultimately forming
The shape of case；For example, when first substrate and second substrate are rectangle, rectangular box-like hollow out figure can be set on mask plate
Case；It is of course also possible to according to concrete scene needs, pierced pattern is arranged to into other shapes, for example, it is also possible in rectangular centre
Increase other hollow out figure, further to improve the adhesive strength between first substrate and second substrate.
The touch screen applying method that the present embodiment is provided, coordinates mask plate on the first substrate by using aqueous adhesive
The aqueous binders pattern that formation is matched with the pierced pattern on mask plate, then solidify aqueous adhesive by exposure, finally
Realize that the reliable laminating between first substrate and second substrate is fixed；The good fluidity of aqueous binders can be utilized so as to
Form evenly thinner adhesive linkage, it is to avoid forms bubble because adhesive linkage local thickness is uneven, improve laminating quality with
Light transmittance；And thickness is thinner, be conducive to reducing the thickness of whole touch screen.
Preferably, the aqueous binders in the present embodiment can be UV glues, the aqueouss bonding formed using the UV glues
The thickness of agent pattern can reach less than 1 micron；
Accordingly, the aqueous binders pattern is exposed in above-mentioned steps 104, specially：
Using ultraviolet light irradiation aqueous binders the second time of pattern, wherein second time can be the 10-15 seconds.
Further, at step 104, the very first time can be 3-5 minutes；3-5 minutes after completion of the exposure are needed
It is interior that second substrate is placed on first substrate, laminating is completed, to ensure adhesive property.
Another embodiment of the present invention provides the mask plate in a kind of touch screen applying method for previous embodiment, please join
According to Fig. 5, the mask plate 3 can include：
Flat matrix, offers the groove 301 of rectangle extension on matrix, groove 301 surrounds pierced pattern 30.When
So, mask plate 3 can also be made up of two parts of split, i.e. the rectangular slab of the housing of the rectangle of periphery and inside, housing and square
Gap is formed between shape plate, to surround above-mentioned pierced pattern 30.
The mask plate provided using the present embodiment can be realized being formed on the first substrate and the pierced pattern on mask plate
The aqueouss adhesive pattern of matching, specific operation process are similar with step 101 in previous embodiment and step 102, herein no longer
Repeat.
The mask plate provided using the present embodiment, it is possible to achieve aqueous binders thinner, evenly are formed on substrate
Pattern, it is exposed after can change agglutination adhesive pattern, it is to avoid using local during the mobility such as OCA poor binding agent
The bubble of uneven initiation, it is ensured that laminating quality；In addition, the adhesive pattern for forming preset shape using mask plate can be with
It is convenient to operate, improve laminating efficiency.
Further, pierced pattern 30 also includes the auxiliary through slot being opened on the matrix, and the auxiliary through slot is located at above-mentioned
In rectangular through slot.Preferably, as shown in fig. 6, the auxiliary through slot may include linearly extended bar shaped portion 31, and it is formed at bar shaped
The kink 32 at 31 two ends of portion, and kink 32 is mutually the bar-shaped trough 321 that the first angle stretches out with two.Wherein, aid in logical
The development length of groove can be the difference of the long side with minor face of the first substrate of rectangle, and the first angle can be 90 °.
By increasing auxiliary through slot at middle part, the bonding that further can be improved between first substrate and second substrate is strong
Degree, is particularly suited for larger-size touch screen（Such as more than 7 inches）Attaching process.
Finally it should be noted that：Various embodiments above only to illustrate technical scheme, rather than a limitation；To the greatest extent
Pipe has been described in detail to the present invention with reference to foregoing embodiments, it will be understood by those within the art that：Its according to
So the technical scheme described in foregoing embodiments can be modified, or which part or all technical characteristic are entered
