Embodiment 2
The preparation method of the display panels that the present embodiment discloses is generally identical with embodiment 1, and its difference is that the coating squence of the first adhesive tape 21 and the second adhesive tape 22 is contrary.Please refer to Fig. 6, Fig. 6 is the second edge B gluing along Kuang Jiao district 11, to form second adhesive tape 22 with a stripes, it is Article 4 shape portion 221, then as shown in Figure 7, the first edge A along Kuang Jiao district 11 is coated with the first adhesive tape 21, to form first adhesive tape 21 with three stripes and two the first corner portion, comprising the first stripes 211, second stripes 213, Article 3 shape portion 215, Article 4 shape portion 221, and the first corner portion 212a between the first stripes 211 and the second stripes 213, the first corner portion 212b between the second stripes 213 and Article 3 shape portion 215, and the first stripes 211 of the first adhesive tape 21 and Article 3 shape portion 215 are to form two the second corner portion with Article 4 shape portion 221 intersection of the second adhesive tape 22, it comprises the second corner portion 222a between the first stripes 211 and Article 4 shape portion 221, and the second corner portion 222b between Article 3 shape portion 215 and Article 4 shape portion 221.Then preparation method as described in Example 1, to form gasket seal patterns as shown in Figure 4, and completes display panels as shown in Figure 5.
In addition, in the process of above-described embodiment 1 and the contained frame glue coating of embodiment 2, if the frame glue amount be coated with is too much, be easy to the situation that overflow occurs in the process of first substrate 10 and second substrate 20 pressing, and then affect the display usefulness of viewing area 12, and reduce product confidence level.And in display panels provided by the present invention, in time being coated with frame glue, glue frame due to the second corner portion 222a and the second corner portion 222b is formed by the first adhesive tape 21 and the second adhesive tape 22 intersection, therefore will more frame glue amount be had in two second corner portion 222a, 222b, the overflow of frame glue may be caused when pressing.
Therefore, in order to avoid the overflow of frame glue, the second substrate 20 of embodiment 1 and embodiment 2 can comprise one or more separation material 31, as shown in FIG. 8 and 9, wherein, Fig. 9 is the cut-open view of a '-a tangent line in Fig. 8, and separation material 31 is arranged between two the second corner portion 222a ', the frame glue of 222b ' and viewing area 12, and be arranged in Kuang Jiao district 11, to be barred from the overflow of pressing program time-frame glue to viewing area 12.But implement in aspect in other, separation material 31 can be other kenels, is not particularly limited, and prevent the overflow of frame glue, and separation material 31 can be formed on first substrate 10 as long as can reach.
In addition, the first substrate 10 of embodiment 1 and embodiment 2 can comprise a groove 32, its as shown in Figures 10 and 11, wherein, Figure 11 is the cut-open view of a '-a tangent line in Figure 10.Groove 32 is arranged on first substrate 10, and corresponds to this second corner portion 222a ' and the second corner portion 222b ', and thus, frame glue unnecessary when pressing can be filled in groove 32, to avoid in overflow to viewing area 12.And the groove 32 shown in Figure 10 is the groove of triangular form, but implement in aspect in other, the shape of groove 32 is not particularly limited, and prevents the overflow of frame glue as long as can reach, and implements in aspect in other, and groove 32 can be formed on second substrate 20.
Or in display panels provided by the present invention, can have one or more separation material 31 and groove 32, as shown in Figure 12 and Figure 13, wherein, Figure 13 is the cut-open view along a '-a tangent line in Figure 12 simultaneously.Wherein, separation material 31 is arranged on second substrate 20, between the frame glue and viewing area 12 of the second corner portion 222a ', 222b ', and is arranged in Kuang Jiao district 11; And groove 32 is arranged on first substrate 10, and correspond to this second corner portion 222a ', 222b '.
Above-described embodiment is citing for convenience of description only, and the interest field that the present invention advocates from should being as the criterion with described in claim, but not is only limitted to above-described embodiment.
