Abstract
The utility model provides a touch screen with firm bonded positions. The touch screen comprises a protective film, a lens, an optical cement layer and an ITO (indium tin oxide) thin film which are sequentially stacked, wherein an FPC (flexible printed circuit) is pressed between the lens and the ITO thin film, the FPC is bonded with the lens through a conductive adhesive layer, and the FPC is also connected with the lens through a double-sided adhesive layer. According to the touch screen provided by the utility model, because the FPC is connected with the lens through the double-sided adhesive layer, when a relatively large upward tensile force is exerted on the FPC, a first stressed part is the double-sided adhesive layer, and a bonded position of the conductive adhesive layer can not be pulled, so that the double-sided adhesive layer achieves a protection effect on the bonded position of the conductive adhesive layer, thereby effectively solving the bad problems that the bonded position of the conductive adhesive layer easily has loosing, pull-off or line micro-fracture phenomena and the like; meanwhile, the double-sided adhesive layer is sealed around a bonded area of the conductive adhesive layer, so that the sealing effect of the bonded area of the conductive adhesive layer can be increased, thereby increasing the reliability of products in environment tests such as high temperature, high humidity and salt spray tests and the like.
Description
Technical field
The utility model belongs to touch screen technology field, relates in particular to the touch-screen of a kind of nation firm position.
Background technology
In order to be improved monolithic stability, the reliability standard of touch-screen, nearly 2 years industry personages, unanimously finding how to improve the fixed stable design method of product touch-screen nation, make the guarantee that product is more mature and stable, have more firm quality and serviceable life.
As shown in Figure 1; existing touch-screen comprises diaphragm 91, eyeglass 92, optics glue-line 93 and the ito thin film 94 being cascading; between eyeglass 92 and ito thin film 94, also pressing has a FPC (flexible circuit board) 95; FPC95 is fixed stressed with eyeglass 92 nations by conducting resinl 96; when FPC95 is subject to larger pulling force, the nation of FPC95 location easily occurs getting loose, pulling or the bad phenomenon such as circuit micro-fracture.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the touch-screen of a kind of nation firm position is provided.
The utility model is to realize like this; the touch-screen of a kind of nation firm position; comprise the diaphragm, eyeglass, optics glue-line and the ito thin film that are cascading; between described eyeglass and ito thin film, also pressing has a FPC; by a conductive adhesive layer and described eyeglass nation calmly, described FPC is also connected with described eyeglass by a layers of two-sided described FPC.
Particularly, described layers of two-sided and described conductive adhesive layer interval arrange.
Particularly, between described layers of two-sided and conductive adhesive layer, be spaced apart 0.3mm～0.5mm.
Particularly, the thickness of described layers of two-sided and conductive adhesive layer is 0.05mm～0.25mm.
The touch-screen that the utility model provides, FPC is connected with eyeglass by layers of two-sided, when FPC is subject to making progress larger pulling force, first stressed position is layers of two-sided, and draw the nation's allocation less than conductive adhesive layer, layers of two-sided plays a protective role to the nation location of conductive adhesive layer, getting loose easily appears in the nation location that effectively solves conductive adhesive layer, pull or the bad problem such as circuit micro-fracture, layers of two-sided is sealed in around conductive adhesive layer Bang Ding region simultaneously, can increase the sealing effectiveness that conductive adhesive layer nation locates surely, improving product is at high temperature, high humidity, the reliability of the environmental testings such as salt-fog test.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the touch-screen that provides of prior art.
Fig. 2 is the schematic diagram of the touch-screen that provides of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 2; the touch-screen of a kind of nation firm position that the utility model embodiment provides; comprise the diaphragm 11, eyeglass 12, optics glue-line 13 and the ito thin film 14 that are cascading; between eyeglass 12 and ito thin film 14, also pressing has a FPC15; FPC15 is fixed with eyeglass 12 nations by a conductive adhesive layer 16, and FPC15 is also connected with eyeglass 12 by a layers of two-sided 17.
The touch-screen that the utility model provides, FPC15 is connected with eyeglass 12 by layers of two-sided 17, when FPC15 is subject to making progress larger pulling force, first stressed position is layers of two-sided 17, and draw the allocation less than conductive adhesive layer 16 nation, 17 pairs of conductive adhesive layer 16 nation location of layers of two-sided play a protective role, effectively solving conductive adhesive layer 16 nation location easily occurs getting loose, pull or the bad problem such as circuit micro-fracture, layers of two-sided 17 is sealed in around conductive adhesive layer 16Bang Ding region simultaneously, can increase the sealing effectiveness that conductive adhesive layer 16 nations locate surely, improving product is at high temperature, high humidity, the reliability of the environmental testings such as salt-fog test.
Particularly, described layers of two-sided 17 arranges with conductive adhesive layer 16 intervals, between layers of two-sided 17 and conductive adhesive layer 16, be spaced apart 0.3mm～0.5mm, make to have certain laminating deviation between layers of two-sided 17 and conductive adhesive layer 16, avoided layers of two-sided 17 and conductive adhesive layer 16 nation to locate and occurred overlapping phenomenon.
Particularly, the thickness of described layers of two-sided 17 and conductive adhesive layer 16 is 0.05mm～0.25mm, the thickness that is layers of two-sided 17 equates with the thickness of conductive adhesive layer 16, thereby has guaranteed the flatness after FPC15 fits with eyeglass 12 by layers of two-sided 17, conductive adhesive layer 16.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
