Abstract
The utility model discloses a water vapor infiltration prevented touch screen, belonging to the technical field of the manufacturing and designing of touch screens. The touch screen comprises an upper layer with a conductive film (ITO (Indium Tin Oxide)), a lower layer with a conductive film (ITO), a leading-out wire and a wire bond which is used for bonding the upper layer and the lower layer, wherein the wire bond is provided with a first hollowed gap, and the leading-out wire is arranged in the first hollowed gap. The touch screen further comprises a sealing adhesive, wherein a second hollowed gap communicated with the first hollowed gap is formed in the upper layer corresponding to the position of the leading-out wire, and the sealing adhesive is arranged at the second hollowed gap and seals the first hollowed gap. Through the technical scheme that the upper layer is hollowed and the sealing adhesive is additionally arranged, the width and thickness of the sealing adhesive are increased, so that the control is easy during production, the phenomena, such as bulging, do not occur, and the water vapor infiltration preventing effect is better. The touch screen has the advantages that the sealing effect is good, the processing mode is simple, and the circumstances that subsequent working procedures are complicated and difficult cannot be caused.
Description
Technical field
The utility model relates to a kind of touch-screen designing for manufacturing technology, specifically, particularly relates to the touch-screen that a kind of anti-steam infiltrates.
Background technology
At present, with each layer of touch-screen structure pressing one the time, general extension line (FPC) is horizontal measuring, and its lower end is from profile, and namely the edge is too near, therefore, be used for the double faced adhesive tape of bonding upper strata (TOP ITO.FILM) and lower floor (BOTTOM ITO.FILM) herein---be that the line key is too narrow, through can rolling or break after processing, usually way is that line key is herein hollowed out, as Fig. 1, Fig. 2 and shown in Figure 3.
But, space after hollowing out easily causes steam to infiltrate, and for this reason, people have taked again many kinds of measures, as the upper protrusion of film (FILM) 0.15mm on the upper strata, as sealing use, as shown in Figure 4, still, such design because of the position of protruding just in time around the corner, upper machine to postorder is influential, and the sealing width of 0.15mm, and is also wayward when producing; Also having a kind of method is to adopt the mode of encapsulating, and as shown in Figure 5, but upper thickness only has 0.188mm herein, and encapsulating 6 is more difficult operation also, and can produce the phenomenon of heaving.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and the touch-screen that provides a kind of anti-steam to infiltrate has good sealing effect, and processing mode is simple, can not cause the advantage of postorder complex procedures difficulty.
Its technical scheme is as follows: the touch-screen that a kind of anti-steam infiltrates comprises the upper strata of being with conducting film (ITO), the line key of being with lower floor, extension line, bonding upper strata and the lower floor of conducting film (ITO); Described line key is provided with first and hollows out the gap, and described extension line is placed in described first and hollows out the gap; Also comprise sealing, described upper strata with corresponding position, extension line position be provided with first hollow out that the gap communicates second hollow out the gap, described sealing is located at described second and is hollowed out gap location and seal described first and hollow out the gap.
By the upper strata is hollowed out, then increase the technical scheme of sealing, because width and the thickness of sealing increases, not only easily control when producing, do not produce and the phenomenon such as heave, also having preferably, anti-steam infiltrates effect.
The below describes further technical scheme:
In certain embodiments, described sealing is concordant with the upper surface on upper strata.Do not affect machine in the processing of touch-screen postorder, and have advantages of attractive in appearance.
In certain embodiments, described first hollow out the gap and extend to the touch-screen edge.Be beneficial to being connected of extension line and other parts.
In certain embodiments, described second hollow out the gap and extend to the touch-screen edge.In order to increase the operations area of touch-screen as far as possible, extension line arrange as far as possible with near touch-screen edge, therefore it is all extended to the touch-screen edge and can make manufacturing procedure simple, yields is high.
In certain embodiments, described sealing is positioned at the touch-screen edge around extension line.After sealing, anti-steam infiltrates effective.
In certain embodiments, described extension line lower end is 0.8-1.2mm apart from the touch-screen Edge Distance.To increase the operations area of touch-screen as far as possible.
In certain embodiments, described extension line lower end is apart from the preferred 0.97mm of touch-screen Edge Distance.This distance is to consider the optimum distance that draws after the maximization of touch screen operation area and production process feasibility.
In certain embodiments, described upper strata is poly terephthalic acid class film, and described lower floor is that poly terephthalic acid class film, glass, poly terephthalic acid class film add a kind of in plastic base.The material of the upper and lower arranges according to the actual requirements.
The below describes the advantage of aforementioned techniques scheme:
The touch-screen that anti-steam of the present utility model infiltrates by the upper strata is hollowed out, then increases the technical scheme of sealing, because width and the thickness of sealing increases, not only easily controls when producing, and does not produce the phenomenon such as to heave, and also having preferably, anti-steam infiltrates effect.Have good sealing effect, processing mode is simple, can not cause the advantage of postorder complex procedures difficulty.

Embodiment
The below is elaborated to embodiment of the present utility model:
As Fig. 6, the touch-screen that a kind of anti-steam infiltrates comprises the line key 1 of lower floor, extension line 2, bonding upper strata 5 with the lower floor of upper strata 5, the band conducting film (ITO) of band conducting film (ITO); Described line key 1 is provided with first and hollows out gap 4, and described extension line 2 is placed in described first and hollows out gap 4; Also comprise sealing 3, described upper strata 5 with extension line 2 corresponding positions, position be provided with first hollow out that gap 4 communicates second hollow out the gap, described sealing 3 is located at described second and is hollowed out gap location and seal described first and hollow out gap 4, as shown in Figure 7.
