Moreover in the structure design, non-optical level protective seam 152 is different from optical grade protective seam 151 parts and is, described non-optical level protective seam 152 only is coated on part decorative layer 12 and the part line layer 14.

Similar to optical grade protective seam 151 material behaviors; when this non-optical level protective seam 152 reaches certain condition, be higher than 160 ℃ such as softening temperature, and the hardness of this non-optical level protective seam 152 is greater than 2H; can make non-optical level protective seam 152 have better protection effect, but not be subject to this.

Described molded shell 2 has an outer face 21, and above-mentioned outer face 21 is connected in cover plate 11 outside surfaces 112, and the outside surface 112 of the outer face 21 of molded shell 2 and cover plate 11 is seated on the same level face.

Please refer to Fig. 5, to illustrate the schematic flow sheet that the utility model provides a kind of manufacture method of contact panel module in addition, its step comprises: form an integrated panel (step S50) and form a molded shell (step S52) in the Inset ejection molding mode, wherein this integrated panel defines a see-through area and is positioned at a see-through area non-see-through area on every side, and this cover plate has a relative inside surface and an outside surface.

Wherein, the method for the integrated panel of formation step S50 comprises: a decorative layer is set in the inside surface of this cover plate and is positioned at this non-see-through area (step S510); One sensing electrode layer is set in the inside surface of this cover plate and is positioned at this see-through area (step S520), wherein the sensing electrode layer can further extend on the decorative layer; One line layer (step S530) on this decorative layer is set, and this line layer and the electric connection of this sensing electrode layer; One protective seam (step S540) is set, and this protective seam is coated on part decorative layer and the part line layer at least.

Wherein, please refer to Fig. 6 to Fig. 9, is the utility model forms the molded shell of step S52 in the Inset ejection molding mode schematic flow sheet.

At first, see also shown in Figure 6, one set of molds 200 for Jet forming machine is provided, it comprises a fixed mould 201 and and moves moulds 202, and fixed mould 201 surrounds with 202 inner edges that move moulds and defines a die cavity 203, wherein, described die cavity 203 has the type body of prefabricated contact panel module 100, that is die cavity 203 comprises the volume that is enough to arrange integrated panel 1 and shaping molded shell 2.

Please consult shown in Figure 7ly again, integrated panel 1 is inserted in the die cavity 203 of above-mentioned set of molds 200 with as the imbedding piece in the die cavity 203, the edge of described integrated panel 1 defines a shell space 204 with set of molds 200 encirclements.Wherein, cover plate 11 outside surfaces 112 of integrated panel 1 are connected to fixed mould 201 inner edges; and 202 inner edges that move moulds are connected on the protective seam 15 of integrated panel 1; protective seam 15 can be optics protective seam 151 shown in Figure 2 or non-optical level protective seam 152 shown in Figure 4, and wherein the softening temperature of protective seam 15 is higher than 160 ℃ and hardness greater than 2H.

Please consult again shown in Figure 8; from moving moulds 202 injections, one molten plastic 2 ' to shell space 204; after the pressurize cooling, namely form described molded shell 2 again; so that integrated panel 1 forms described contact panel module 100 with molded shell 2 combinations; wherein, part molded shell 2 is positioned at non-see-through area and is formed on the protective seam 15 and part molded shell 2 coats the edge of integrated panel 1.This molded shell 2 has an outer face, and this outer face is connected in this cover plate outside surface, and this outer face and this outside surface are seated on the same level face.

Wherein, when injection molten plastic 2 '; decorative layer 12 and the protection (buffering with heat insulation) of line layer 14 through protective seam 15; make it reduce directly possibility of contact molten plastic 2 ', and then avoid the color of decorative layer 12 or pattern generating changes and the pressure of avoiding line layer 14 to produce because of injection molten plastic 2 ' produces wire 141 and ruptures.Moreover protective seam 15 helps avoid especially decorative layer 12 and produces the damages such as scratch with line layer 14 in said process, can avoid by this flimsy problem in contact panel module frontside edge zone.

Please consult shown in Figure 9ly, last die sinking is taken out contact panel module 100 and is namely finished manufacturing process again.

Employed element in this manufacture method embodiment, all identical with previous embodiment, namely repeat no more at this.

The above only is embodiment of the present utility model, and it is not to limit to claim of the present utility model.
