Detailed description of the invention
The flow chart of the touch-screen applying method that Fig. 1 provides for one embodiment of the invention; As shown in Figure 1, the invention provides a kind of touch-screen applying method, comprising:
Step 101, mask plate to be covered on the surface of first substrate, and on mask plate even spread aqueous binders, to form the aqueous binders layer be covered on mask plate and first substrate.
As shown in Figure 2, can by first substrate 21 horizontal positioned bench top to be fit, again mask plate 3 is placed into first substrate 21 surface upward, wherein mask plate 3 has pierced pattern 30, make first substrate 21 surface to should the part of pierced pattern expose; Aqueous adhesive layer is uniformly coated on the position of mask plate 3 and the corresponding pierced pattern of first substrate 21 by the instruments such as later use brush, thus forms the aqueous adhesive layer being covered in the upper that mask plate 3 and first substrate 21 are exposed by the pierced pattern on mask plate 3.
Step 102, remove aforementioned mask plate, make the surface of first substrate stays the aqueous binders pattern 23(that mates with the pierced pattern on mask plate as shown in Figure 3); Namely, please refer to Fig. 2 and Fig. 3, block effect due to mask plate 3, make the position of the pierced pattern 30 of first substrate on the surface only on corresponding mask plate 3 also leave aqueous binders, and the pattern that the aqueous binders stayed surrounds just mates with the pierced pattern on mask plate 3.
Step 103, aqueous binders pattern to be exposed, make aqueous binders solidify to form colloidality adhesive pattern.
Particularly, expose the light type adopted, and the parameter such as time for exposure can be determined according to concrete aqueous binders, namely by the light of particular type (such as, ultraviolet, infrared ray etc.) irradiate this aqueous binders certain hour after, it can be made to be the gluey state of semi-solid preparation by good fluidity, watery State Transferring.Further, the shape of the colloidality adhesive pattern formed after exposure does not change compared with the aqueous binders pattern before exposure, and only its mobility obviously declines, and is convenient to follow-up laminating operation.
Step 104, in the very first time after aqueous binders pattern exposure, second substrate to be stacked and placed on above-mentioned first substrate, and to carry out pressing, 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 first substrate 21 and there is the side of colloidality adhesive pattern on the surface, then, pressure roller can be utilized from the surface roll-in of first substrate 21 opposite side, thus make together with first substrate 21 and second substrate 22 be reliably adhesively fixed by this colloidality adhesive pattern.
It should be noted that, the first substrate in the present embodiment and second substrate can be as the glass plate of particular functional layer, nesa coating etc. in touch-screen; Further, namely the pierced pattern on mask plate determines the shape of the final colloidality adhesive pattern formed; Such as, when first substrate and second substrate are rectangle, mask plate can arrange rectangular box-like pierced pattern; Certainly, also according to concrete scene needs, pierced pattern can be arranged to other shape, such as, other hollow out figure can also be increased in rectangular centre, to improve the adhesive strength between first substrate and second substrate further.
The touch-screen applying method that the present embodiment provides, mask plate is coordinated to form the aqueous binders pattern mated with the pierced pattern on mask plate on the first substrate by utilizing aqueous adhesive, by exposure, aqueous adhesive is solidified again, the reliable laminating finally realized between first substrate and second substrate is fixed; The good fluidity of aqueous binders can be utilized, make it be formed evenly thinner adhesive linkage, avoid because adhesive linkage local thickness is uneven and form bubble, improve laminating quality and light transmittance; And thickness is thinner, be conducive to the thickness reducing whole touch-screen.
Preferably, the aqueous binders in the present embodiment can be UV glue, and the thickness of the aqueous binders pattern utilizing this UV glue to be formed can reach less than 1 micron;
Accordingly, in above-mentioned steps 104, this aqueous binders pattern is exposed, is specially:
Utilize ultraviolet light irradiation aqueous binders pattern second time, wherein this second time can be 10-15 second.
Further, at step 104, the very first time can be 3-5 minute; Namely need in 3-5 minute, second substrate to be placed on first substrate after completion of the exposure, to complete laminating, to ensure adhesive property.
Another embodiment of the present invention provides a kind of and please refer to Fig. 5 for the mask plate in the touch-screen applying method of previous embodiment, and this mask plate 3 can comprise:
Flat matrix, matrix offers the groove 301 that rectangle extends, groove 301 surrounds pierced pattern 30.Certainly, mask plate 3 also can be made up of two parts of split, and the housing of namely peripheral rectangle and inner rectangular slab, form gap between housing and rectangular slab, to surround above-mentioned pierced pattern 30.
The mask plate utilizing the present embodiment to provide can be implemented in the water-based binder pattern that on first substrate, formation is mated with the pierced pattern on mask plate, in specific operation process and previous embodiment step 101 and step 102 similar, repeat no more herein.
Utilize the mask plate that the present embodiment provides, can be implemented in substrate formed thinner evenly aqueous binders pattern, gluey adhesive pattern can be converted to after exposure, avoid the bubble of the uneven initiation in local during the binding agent adopting the mobility such as OCA poor, ensure that laminating quality; In addition, utilize mask plate to form all right handled easily of adhesive pattern of preset shape, improve laminating efficiency.
Further, pierced pattern 30 also comprises the auxiliary through slot be opened on this matrix, and this auxiliary through slot is positioned at above-mentioned rectangular through slot.Preferably, as shown in Figure 6, this auxiliary through slot can comprise linearly extended bar shaped portion 31, and is formed at the kink 32 at two ends, bar shaped portion 31, and kink 32 has two bar-shaped troughs 321 being mutually the first angle and stretching out.Wherein, the development length of auxiliary through slot can be the long limit of the first substrate of rectangle and the difference of minor face, and the first angle can be 90 °.
By increasing auxiliary through slot at middle part, the adhesive strength between first substrate and second substrate can be improved further, be particularly useful for the attaching process of larger-size touch-screen (such as more than 7 inches).
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
