Still be able to have after in gap with 40 comparable glue amount of outside glue bearing areas, and then be effectively improved glue curing Hou Ge roads gluing
The uniformity in region 40.
In above-mentioned preferred embodiment, can only it make close to first group of adjacent glue bearing areas 40 of first edge
Divide and overlap to form overlapping region 410, as shown in figure 5, at this point, the preceding twice in close gap between upper substrate 10 and lower substrate 20
Glue bearing areas 40 has more glue amounts compared to other glue bearing areas 40, so as to which glue be enable to be filled into seam as much as possible
In gap；When carrying out the number of coating process on region 210 to be coated more than n times (n is more than 3), can also make close to first
Adjacent glue bearing areas 40 partially overlaps to form overlapping region 410, at this time in first to the n-th road glue bearing areas 40 at edge
It is preferred that the number of above-mentioned coating process is more than or equal to, (n × 2) are secondary, so as to make close to the inside glue bearing areas 40 in gap compared to outer
Side glue bearing areas 40 can have more glue amounts, and then the glue in inside glue bearing areas 40 is filled to gap, inside
Glue bearing areas 40 still is able to have comparable glue amount with outside glue bearing areas 40, to improve glue curing Hou Ge roads glue bearing areas 40
Uniformity.
In above-mentioned preferred embodiment, it can also make between adjacent each group glue bearing areas 40 that there are overlapping regions
410, at this point, by making the overlapping region 410 between the inside glue bearing areas 40 in gap compared to outside glue bearing areas 40
Between overlapping region 410 there is the width of bigger, also can in Shi Ge roads glue bearing areas 40 close to the inside in gap compared to
Outside has more glue amounts, so as to which glue be enable to be filled into gap as much as possible.
In order to which glue as much as possible is enable to enter between upper substrate 10 and lower substrate 20 in gap, and further carry
Uniformity of the high glue in gap and outside gap, it is further preferable that the width of glue bearing areas 40 is 0.5~0.8mm, it is adjacent
The width of overlapping region 410 is more than 0 and less than or equal to 0.3mm in glue bearing areas 40.
It, can also be by repeatedly being applied on above-mentioned region 210 to be coated other than above-mentioned preferred embodiment
During cloth technique, increase in coating process close to the coating process at least once of first edge on region 210 to be coated
The glue amount of coating so as to the glue amount by adjusting the slot edge between two substrates, makes to penetrate into the glue amount in gap and increases
Add.
In the glue sealing method of the above-mentioned display screen frame of the present invention, gap is infiltrated into order to which Shi Ge roads glue bearing areas has
The interior time difference, it is preferable that it is above-mentioned carry out multiple coating process on region 210 to be coated during, make each time coating
1~5s is divided between the initial time of technique.One of glue bearing areas 40 is coated after above-mentioned interlude can make
Cheng Zhong, Qian Dao glue bearing areas 40 has gap penetration of the sufficient time between two substrates, so as to extend preceding road gluing
The time of penetration in region 40 increases the glue amount penetrated into gap, be also effectively improved after glue curing in gap and
The uniformity of solidification glue outside gap.In a preferred embodiment, it in above-mentioned glue sealing method, is carried out along first edge
First time coating process, so that projection of the first edge on region 210 to be coated is located in glue bearing areas 40.Above-mentioned preferred
Embodiment in, the glue bearing areas 40 formed by first time coating process can be close between upper substrate 10 and lower substrate 20
Gap, so that more glue can not only be made to enter in above-mentioned gap, additionally it is possible to improve the efficiency of sealing adhesive process.
In the glue sealing method of the above-mentioned display screen frame of the present invention, coating process can be that gluing process or slit spray
Technique, preferably electric spray type dispensing, but above-mentioned coating type is not limited to, those skilled in the art can be according to the prior art
Rational choice is carried out to the type of coating process.Those skilled in the art can also be according to the prior art to being coated on area to be coated
Glue type on domain 210 carries out Rational choice, in order to improve the sealing effect to display screen frame, it is preferable that above-mentioned glue
Selected from TUFFY glue, silicon rubber and UV glue any one or more ofs.
In the glue sealing method of the above-mentioned display screen frame of the present invention, after multiple glue bearing areas 40 are formed, above-mentioned envelope
Gluing method can also include will be in above-mentioned each glue bearing areas 40 the step of glue curing.Due in the multiple glue bearing areas of above-mentioned formation
In 40 the step of, the glue in Qian Dao glue bearing areas 40 can be gradually to two bases in the coating process of Hou Dao glue bearing areas 40
The direction movement in gap between plate, so as to penetrate into the paste portion in the glue bearing areas 40 of 10 first edge of upper substrate
In above-mentioned gap, the relative increase time of penetration of glue so as to save the stand-by period of glue, without waiting can be right
Glue carries out curing schedule, while can make in the more gaps between substrate of the solid gum to be formed 50, such as Fig. 6 institutes
Show.
The present invention above-mentioned display screen frame glue sealing method in, display screen can also include be set to upper substrate 10 with
Sealing element 30 between lower substrate 20, which can be rectangle or ring-type, between upper substrate 10 and lower substrate 20
Liquid crystal material be located in above-mentioned sealing element 30, sealing element 30 is used between liquid crystal material is sealed in two substrates, at this time upper base
Plate 10 has is formed with accommodation space between one end, sealing element 30 and the lower substrate 20 of first edge, which is located at seam
In gap, at this time in above-mentioned glue sealing method, by forming multiple glue bearing areas 40, so that glue more penetrates into accommodation space
In, the solid gum 50 being filled in accommodation space is formed after curing, as shown in Figure 6.
The glue sealing method of the display screen frame of offer is be provided below in conjunction with embodiment.
Embodiment 1
