Embodiment
Below in conjunction with drawings and the specific embodiments, touch-screen is further described.
As shown in Figure 1, the touch-screen 10 of an embodiment, comprises body 100, flexible PCB 200 and fixture 300.
Body 100 comprises folded substrate 110, touch-control sensing layer 120 and the diaphragm 130 established successively.Wherein, touch-control sensing layer 120 is for determining the coordinate of touch point.
Flexible PCB 200 is in bending, and partially flexible circuit board 200 is between diaphragm 130 and substrate 110, and is electrically connected with touch-control sensing layer 120, and partially flexible circuit board 200 is positioned on the surface of diaphragm 130 away from touch-control sensing layer 120.Wherein, being positioned at diaphragm 130 away from the part on the surface of touch-control sensing layer 120 is folding part 210.
Fixture 300 comprises the second district 320 being positioned at the first middle district 310 and being positioned at two ends.First district 310 and the side contacts of folding part 210 away from diaphragm 130, the second district 320 and the surface contact of diaphragm 130 away from touch-control sensing floor 120.Wherein, the acting force between the first district 310 and folding part 210 is less than the acting force between the second district 320 and diaphragm 130.
Flexible PCB 200 is bent on diaphragm 130 by above-mentioned touch-screen 10, and adopts fixture 300 to be fixed on diaphragm 130 folding part 210, thus makes above-mentioned touch-screen 10 can meet shipment requirement.And first acting force between district 310 and folding part 210 be less than acting force between the second district 320 and diaphragm 130, thus when tearing off fixture 300, the situation causing because of larger tearing force occurring damaging flexible PCB 200 can be avoided.
As shown in Figure 2, in the present embodiment, fixture 300 comprises substrate 330, glue-line 340 and hides glued membrane 350.Glue-line 340 is located in substrate 330, comprises two the first glue districts 342 and a second glue district 344.Two the first glue districts 342 are for forming two the second districts 320.Second glue district 344 between two the first glue districts 342, and overlaps with two the first glue districts 342.Hiding glued membrane 350 is located in the second glue district 344, for forming the first district 310.
Because two the second districts 320 have viscosity, thus the flexible PCB 200 after bending can be fixed on diaphragm 130 by fixture 300.And the first district 310 does not have viscosity, thus when being torn off from diaphragm 130 with flexible PCB 200 by fixture 300, there will not be the problem damaging flexible PCB 200 because tearing force is comparatively large.
Further, in the present embodiment, two the first glue districts 342 and second glue district 344 bounding force identical, thus make above-mentioned fixing piece 300 be very easy to make.Concrete, first at blade coating one deck glue-line 340 on the surface of substrate 330, then on glue-line 340, paste one hide glued membrane 350.Be appreciated that in other embodiments, when the bounding force in the second glue district 344 is less than the bounding force in the first glue district 342, hides glued membrane 350 and also can omit.
Further, in the present embodiment, the thickness in the second district 320 is 0.08mm, and the thickness hiding glued membrane 350 is less than or equal to 0.05mm.Wherein, it should be noted that, the thickness in the second district 320 is the thickness of substrate 330, the thickness in the second glue district 344 and the thickness sum of screening glued membrane 350.Concrete, substrate 330 is PET film, and hiding glued membrane 350 is release liners.
As shown in Figure 3, in another embodiment, fixture 300 comprises substrate 330 and is provided with the glue-line 340 in substrate 330.Glue-line 340 comprises two the first glue districts 342 of 342, two, the first glue district for forming two the second districts 320, and the part of substrate 330 between two the first glue districts 342 is for forming the first district 310.The fixture 300 of fixture 300 in Fig. 3 relatively in Fig. 2 can omit one and hide glued membrane 350 and part glue-line 340, but due to two the first glue districts 342 be separate, the fixture 300 in relative Fig. 3, it makes relative complex.
As shown in Figure 4, in another embodiment, fixture 300 comprises substrate 330, glue-line 340 and adhesive tape 360.Glue-line 340 is provided with in substrate 330, and comprises two the first glue districts 342 of 342, two, the first glue district for forming two the second districts 320.Adhesive tape 360 has and relative has glue surface (not shown) and glue-free surperficial (not shown), adhesive tape 360 is between two the first glue districts 342, and having glue surface to be affixed in substrate 330, glue-free surface flushes away from the surface of substrate 330 with the first glue district 342.Fixture 300 in Fig. 2 and Fig. 3 is away from the air spots of substrate 330, and the fixture 300 in Fig. 4 can well solve the problem in Fig. 2 and Fig. 3.
Conveniently fixture 300 is torn off from diaphragm 130 and flexible PCB 200; as shown in Figure 2; in the present embodiment, fixture 300 also comprises one or two Si Shou district 370, and each Si Shou district 370 is connected away from the side in the first district 310 with one second district 320.Si Shou district 370 and the surface contact of diaphragm 130 away from touch-control sensing floor 120, the acting force between Qie Sishou district 370 and diaphragm 130 is less than the acting force between the second district 320 and diaphragm 130.
Concrete, the one end in substrate 330 two ends or the two ends of substrate 330 stretch out and form an extension 332 or two extensions 332.An extension 332 or two extensions 332 are respectively used to form one or two Si Shou district 370.Because Si Shou district 370 does not have viscosity, thus be convenient to workman personnel and lift fixture 300, so that fixture 300 is torn off from diaphragm 130 and flexible PCB 200.Be appreciated that in other embodiments, glue-line can be set between Si Shou district 370 and diaphragm 130, thus can effectively prevent Si Shou district 370 from tilting.
Further, as shown in Figure 5, in the present embodiment, glue-line 340 also comprises one or two the 3rd glue district 346, and the number in the 3rd glue district 336 is less than or equal to the number of extension 332, and each the 3rd glue district 346 is located on an extension 332.Wherein, the bounding force in the 3rd glue district 336 is less than the bounding force in the first glue district 332.Concrete, the first glue district 332 is high temperature glue-line, and the 3rd glue district 336 is the glue-line on masking tape.The arranging to imitate of 3rd glue district 336 prevents Si Shou district 370 from tilting.
When extension 332 only has one, above-mentioned fixing piece 300 only has a Ge Sishou district 370, and this Si Shou district 370 has viscosity.
When extension 332 has two, above-mentioned fixing piece 300 You Lianggesi hand district 370, and this Liang Gesishou district 370 exists following two kinds of situations: the first situation, when the number in the 3rd glue district 336 only has one, one Ge Sishou district 370 has viscosity, and another does not have viscosity; Second situation, when the number in the 3rd glue district 336 has two, Liang Gesishou district 370 all has viscosity.
In the present embodiment, touch-screen 10 also comprises chip 400.Chip 400 is positioned on the surface of diaphragm 130 away from touch-control sensing layer 120, and is electrically connected with folding part 210, and the first district 310 contacts with chip 400.Also namely, fixture 300 fixing flexible circuit board 200 and chip 400 simultaneously.Be appreciated that in other embodiments, fixture 300 also can not contact with chip 400.Also chip 400 can be omitted before touch-screen shipment, and after touch-screen shipment, then by downstream manufacturers, chip 400 is assembled on flexible PCB 200.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
