Embodiment
Below will lift display device is the application that example illustrates frame glue of the present invention, but it is not to limit the present invention.It will be recognized by those skilled in the art that frame glue of the present invention can be applicable between two substrates that any needs fit each other.
Fig. 1 is the diagrammatic cross-section of display device in one embodiment of the invention, and Fig. 2 then is the upper viewing view of the display device of Fig. 1.Please be simultaneously with reference to Fig. 1 and Fig. 2, display device 100 comprises first substrate 110, second substrate 120 and frame glue 130.Second substrate 120 is to be disposed at first substrate 110 tops.In the present embodiment, first substrate 110 can be display panel, contact panel or screening glass one of them, second substrate 120 then is wherein another of display panel, contact panel or screening glass, but the invention is not restricted to this.In addition; when it should be noted that second substrate 120 for example for contact panel or screening glass; the upper surface of second substrate 120 or lower surface can have the functional film layer (not shown), and functional film layer is such as can be blow-out disc, anti-dazzle film, anti-reflective film, electromagnetic interference cuticula or its combination etc.
Hold above-mentionedly, first substrate 110 is to fit in each other by frame glue 130 with second substrate 120.That is to say that frame glue 130 is to be disposed between first substrate 110 and the second substrate 120.Specifically, frame glue 130 for example is double faced adhesive tape.In addition, double faced adhesive tape for example can comprise that conductive layer is used for ground connection, with the protection electromagnetic interference (EMI) or avoid static discharge.Frame glue 130 is formed in one, and has first end 132 and the second end 134 that is connected to each other.In other words, frame glue 130 is ring-type, thus with first substrate 110 and second substrate 120 around space 140.In the present embodiment, for example there is air to exist wherein in the space 140.Because frame glue 130 is formed in one, therefore can stop effectively that the contaminant particles of external environment enters between first substrate 110 and the second substrate 120, affect display quality to keep the cleanliness factor between first substrate 110 and the second substrate 120, to be interfered when avoiding light by space 140.
Specifically, frame glue 130 has pre-tangent line C in the junction of first end 132 and the second end 134.Pre-tangent line C is formed on the frame glue 130 in the mode of crush-cutting in advance, and it for example is to have a plurality of aperture (not shown) that are arranged in a straight line, and is beneficial to first end 132 is torn off with the second end 134 easily.Thus, can under the prerequisite of not damaging first substrate 110 and second substrate 120, frame glue 130 be peeled off between first substrate 110 and second substrate 120.Below the stripping means of frame glue 130 will be described for embodiment.
Fig. 3 is the synoptic diagram of one embodiment of the invention center glue in stripping process.Please refer to Fig. 3, when first substrate 110 or second substrate 120 need carry out heavy industry, must first first substrate 110 be separated with second substrate 120.At this moment, the first end 132 of frame glue 130 can be torn off the second end 134 along pre-tangent line C, so that first end 134 partly exposes between first substrate 110 and second substrate 120.Then, can by the part first end 132 that exposes, frame glue 130 be detached between first substrate 110 and second substrate 120.
It is worth mentioning that the first end 132 of frame glue 130 can be designed with the heavy industry mark in contiguous pre-tangent line C part, is beneficial to the related personnel finds pre-tangent line C according to the heavy industry mark position.Specifically, the heavy industry mark can be chimb 131 as shown in Figure 4, and wherein chimb 131 is that bearing of trend evagination along pre-tangent line C is in first end 132.Perhaps, the heavy industry mark also can be breach 231 as shown in Figure 5, and wherein breach 231 is that bearing of trend indent along pre-tangent line C is in first end 132.Thus, the related personnel can be easily by colluding the mode of dialling chimb 131 or breach 231, the first end 132 of frame glue 130 is torn off the second end 134 along pre-tangent line C, and a part of first end 132 of order exposes between first substrate 110 and second substrate 120.Specifically, the related personnel can use the instrument with hook end, it is stretched to collude between first substrate 110 and the second substrate 120 dial chimb 131 or breach 231, but the invention is not restricted to this.
In sum, the present invention is with integrated ring frame glue fit first substrate and second substrate, therefore can keep the cleanliness factor between first substrate and the second substrate.And, because frame glue has pre-tangent line, therefore can easily frame glue be torn into two parts along pre-tangent line, again frame glue is detached between first substrate and second substrate, so that first substrate separates with second substrate, be convenient to carry out follow-up heavy industry technique or the in the future maintenance of end product.Hence one can see that, and the present invention can avoid first substrate or second substrate impaired in the process of peeling off frame glue effectively.Therefore, this frame glue is applied to effectively to improve in the display device heavy industry yield of display device or the in the future maintenance of end product.
Certainly; the present invention also can have other various embodiments; in the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of claim of the present invention.
