Abstract

The invention provides an assembly method of a touch panel. The touch panel comprises protective glass, a sensing layer and an adhesive layer, wherein the adhesive layer is arranged between the protective glass and the sensing layer; a printing ink layer is printed on the edge of the side, facing the sensing layer, of the protective glass; the protective glass is provided with a visible area which is not printed with the printing ink layer. The assembly method of the touch panel comprises the following steps: manufacturing the adhesive layer, wherein the adhesive layer is provided with a middle area and a marginal area surrounding the middle area, the middle area corresponds to the visible layer, the distance between the surface of the middle area and that of the marginal area is equal to the thickness of the printing ink layer, and the marginal area corresponds to the printing ink layer; aligning the middle area and the marginal area of the adhesive layer with the visible area and the printing ink layer, so as to bond the adhesive layer with the printing ink layer in a non-clearance manner; attaching the sensing layer to the adhesive layer. According to the assembly method, the gap between the printing ink layer and the protective glass can be fully filled by the adhesive layer, so as to avoid the generation of bubbles during the attaching of the adhesive layer. The invention further relates to the touch panel assembled according to the assembly method.

Embodiment

As shown in Figures 1 and 2, the contact panel 10 of the embodiment of the invention comprises cover glass 11, ink lay 12, glue-line 13 and sensing layer 14, and glue-line 13 is between cover glass 11 and sensing layer 14.

The area of cover glass 11 and glue-line 13 is all more than or equal to the area of sensing layer 14.When the area of cover glass 11 during greater than the area of sensing layer 14, cover glass 11 can be protected sensing layer 14 better.

In the present embodiment, the area of glue-line 13 equals the area of sensing layer 14, so that the whole binding face of sensing layer 14 is all fitted with glue-line 13.

In other embodiments, the area of glue-line 13 can be slightly less than the area of sensing layer 14, and in other words, the edge of glue-line 13 can be slightly less than the edge of sensing layer 14.

Ink lay 12 is coated on cover glass 11 edge 111 simultaneously and is closed square shape structure, and ink lay 12 is towards sensing layer 14.The zone of cover glass 11 uncoated ink laies 12 is viewing area 110, and ink lay 12 is at least two-layer.

Glue-line 13 comprises zone line 130 and fringe region 131, and fringe region 131 is even round the thickness of zone line 130 and zone line 130 and fringe region 131.Wherein, zone line 130 and fringe region 131 towards the surface of cover glass 11 not on same plane, thereby make glue-line 13 have thickness difference, the thickness of zone line 130 is greater than the thickness of fringe region 131.The viewing area 110 of zone line 130 corresponding cover glasses 11; fringe region 131 corresponding ink laies 12, and the area of fringe region 131 is more than or equal to equaling the thickness d 2 of ink lay 12 so that glue-line 13 and ink lay 12 no gaps applyings apart from d1 between the surface of the surface of the area of ink lay 12 and zone line 130 and fringe region 131.

Zone line 130 has upper surface 1301, side surface 1302 and lower surface 1303, and lower surface 1303 is the lower surface of fringe region 131 simultaneously, and side surface 1302 links to each other with upper surface 1301.Upper surface 1301 is fitted on the cover glass 11; side surface 1302 and ink lay 12 towards the viewing area 110 surface fit and the shape of side surface 1302 and ink lay 12 110 shapes are complementary towards the viewing area; in addition; fringe region 131 fits towards the surface of sensing layer 14 with ink lay 12 and shape is complementary so that glue-line 13 fits tightly with ink lay 12 and do not have bubble, and lower surface 1303 then fits with sensing layer 14.

Glue-line 13 can adopt OCA(Optical Clear Adhesive, optical lens gelatin) glue.

As shown in Figure 3, adopt mould 20 one-body molded making glue-lines 13.Mould 20 has the die cavity 21 of moulding glue-line 13.Die cavity 21 can be for one or more, and namely mould 20 is a mould one cave or multi-point mould.

Die cavity 21 comprises that first forming part 210 and second forming part, 211, the second forming parts 21 are used for zone line 130, the second forming parts 211 of moulding glue-line 13 around first forming part, 210, the first forming parts 210 and are used for the fringe region 131 of moulding glue-line 13.

The material of making glue-line 13 is placed die cavity 21, wait to be full of whole die cavity 21 after, namely plastic glue-line 13 adopts mould 20 once can make one or more glue-lines 13, thereby makes that the parameter of glue-line 13 is identical, the structure homogeneous.

The zone line 130 of the glue-line 13 made is aimed at the viewing area 110 of cover glasses, the ink lay 12 that fringe region 131 is aimed on the cover glasses 11; so that glue-line 13 is attached on the cover glass 11; after treating that glue-line 13 and cover glass 11 attach; sensing layer 14 and glue-line 13 are attached, thereby finish the assembling of contact panel 10.

In the assembling process of contact panel 10; make the glue-line 13 with thickness difference with mould 20 in advance; thickness official post glue-line 13 is fitted with described ink lay 12 no gaps; thereby make glue-line 13 can fill offset between ink lay 12 and the cover glass 11 fully; prevent the generation of bubble when glue-line 13 attaches, improved the yield that contact panel is produced.

Be understandable that those skilled in the art also can do other variation etc. and be used in design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
