Abstract
The utility model discloses a jointing structure of a touch screen. The jointing structure comprises a protective glass layer or PMMA (polymethyl methacrylate) layer, a printing ink layer, a mucilage glue layer and an induction glass layer which are sequentially overlapped, wherein the printing ink layer is printed on the inner surface of the protective glass layer or PMMA layer and is jointed with the induction glass layer through the mucilage glue layer, the mucilage glue layer comprises acrylic acid glue and frame glue, the frame glue is of a frame shape which is hollow inside, and the acrylic acid glue is dispensed on the jointing surface of the induction glass layer within a range limited by the transparent part of the frame glue.
Description
Technical field
The utility model relates to the field of electronic product, and is relevant with a kind of bonding structure of touch-screen.
Background technology
Touch-screen is mainly used in electronic product fields such as mobile phone, digital camera, liquid crystal display module, and touch-screen mainly is divided into OGS(One glass solution), structure such as OFS (One film solution), In cell, G+G, G+F.G+G(Glass of Glass wherein) or P+G(PMMA of Glass) normally adopt transparent optical cement (OCA) to fit, transparent optical cement is a kind of acrylate, utilize the preferable cohesive force of acrylate and adhesion strength both can be closely linked, in the applying process often because the touch screen surface bending, situations such as the too thick or different in nature glass gluing of the ink printing difficulty that causes fitting increases, and the composition surface is easy to generate bubble, therefore after applying, also need to carry out the operation of one froth breaking, and in fact the effect of froth breaking does not become desirable yet, has a strong impact on the quality of product.
The utility model content
In view of this, the utility model provides a kind of touch-screen bonding structure, has overcome the deficiency that is easy to generate bubble in traditional attaching process, thereby effectively guarantees product quality really.
For reaching above-mentioned purpose; the technical solution of the utility model is: a kind of touch-screen bonding structure; comprise the cover glass layer or PMMA layer, printing ink layer, adhesive-layer and the induction glassy layer that stack gradually; this printing ink layer be printed on the inner face of cover glass layer or PMMA layer and and the induction glassy layer between fit together by adhesive-layer; wherein this adhesive-layer is made up of acrylic acid glue and frame glue; it is empty shaped as frame that the structure of frame glue adopts the middle part, and acrylic acid glue is then put glue on the binding face of induction glassy layer in frame glue hollow part restricted portion.
Described frame glue can form with a glue or the double L-shaped single face glue of fitting on the binding face of cover glass layer or PMMA layer or induction glassy layer.
Adopt said structure; behind the acrylic acid glue cloth glue; the cover glass layer slowly is fitted on the induction glassy layer; therebetween acrylic acid glue because of self mobile screen of stream automatically slowly by the centre to around diffusion; like this can be with cover glass layer and induction the bubble between the glassy layer from the centre to around discharge; do not have bubble in the middle of after cover glass layer and induction glassy layer are fitted; therefore the utility model compared with prior art not only can effectively guarantee product quality; and saved available technology adopting transparent optical cement (OCA) applying de-foaming process afterwards, reduce cost; enhance productivity.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model acrylic acid glue cloth glue schematic diagram;
Fig. 3 is acrylate glue current screen schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and concrete enforcement the utility model is elaborated.
As shown in Figure 1; a kind of touch-screen bonding structure of the present utility model; comprise the cover glass layer (or PMMA layer) 1 that stacks gradually; printing ink layer 2; adhesive-layer 3 and induction glassy layer 4; this printing ink layer 2 be printed on the inner face of cover glass layer (or PMMA layer) 1 and and induction glassy layer 4 between fit together by adhesive-layer 3; specifically this adhesive-layer 3 is made up of acrylic acid glue 31 and frame glue 32; it is empty shaped as frame that the structure of frame glue 32 adopts the middle part; can on the binding face of cover glass layer 1 or induction glassy layer 4, form with a glue or the double L-shaped single face glue of directly fitting; acrylic acid glue 31 is then put glue on the binding face of induction glassy layer 4 in frame glue 32 hollow part restricted portions; can carry out cloth glue according to area and the coating thickness of induction glassy layer 4 binding faces during enforcement; conventional acrylic acid glue 31 coating thickness calculate the figure A that cloth glue form goes out as shown in Figure 2 with 0.05-0.25mm.
Adopt said structure; behind the acrylic acid glue 31 cloth glue; cover glass layer 1 slowly is fitted on the induction glassy layer 4; therebetween acrylic acid glue 31 because of self mobile screen of stream automatically slowly by the centre to around diffusion; the direction of acrylic acid glue 31 stream screens is referring to shown in Fig. 3; when acrylic acid glue 31 stream screen when responding to the edge of glassy layer 4; be subjected to the restriction of frame glue 32; acrylic acid glue 31 continues along frame glue 32 edges stream screen; since glue from the centre to around flow; therefore can with the bubble between cover glass layer 1 and the induction glassy layer 4 from the centre to around discharge; do not have bubble in the middle of after cover glass layer 1 and induction glassy layer 4 are fitted; therefore the utility model compared with prior art not only can effectively guarantee product quality; and saved available technology adopting transparent optical cement (OCA) applying de-foaming process afterwards, reduce cost; enhance productivity.
Claims (2)
1. touch-screen bonding structure; comprise the cover glass layer or PMMA layer, printing ink layer, adhesive-layer and the induction glassy layer that stack gradually; this printing ink layer be printed on the inner face of cover glass layer or PMMA layer and and the induction glassy layer between fit together by adhesive-layer; it is characterized in that: this adhesive-layer is made up of acrylic acid glue and frame glue; it is empty shaped as frame that the structure of frame glue adopts the middle part, and acrylic acid glue is then put glue on the binding face of induction glassy layer in frame glue hollow part restricted portion.
