The utility model content

The utility model provides a kind of touch-screen for solving the technical matters that the touch-screen decorative layer strengthens the product integral thickness in the prior art.Concrete technical scheme is following:

A kind of touch-screen; Comprise the upper substrate that stacks gradually, go up transparency conducting layer, go up the conducting wire, go up insulation course, tack coat, insulation course down; Separation layer, following conducting wire, following transparency conducting layer and infrabasal plate; Said upper substrate comprises conductive pattern district and conducting wire district, and the said transparency conducting layer of going up is positioned at the conductive pattern district, also is provided with decorative layer in the conducting wire district of said upper substrate lower surface; Said decorative layer comprises the cabling district, and said upward conducting wire is arranged at said cabling district and insulate with decorative layer.

Further, said cabling district is an insulating material.

Further, said cabling district is the groove that runs through decorative layer.

Further, there are the gap in said upward conducting wire and decorative layer.

Further, said conducting wire and the said decorative layer use same material gone up.

Further, scribble insulating material with said decorative layer same color in the said cabling district.

Further, said insulating material is a printing ink.

Further, the material of said decorative layer is a plated material.

Further, the material of said decorative layer is nickel or aluminium, and the thickness of said decorative layer is less than 1um.

The touch-screen that the utility model provides is through being incorporated into decorative layer among the manufacturing process of touch-screen; With respect to the upper surface that in the prior art decorative layer is covered on touch-screen through bonding coat; The utility model can make the integral thickness attenuate of this touch-screen; And,, make this resistive touch screen reduce cost to a certain extent owing to need not adhere to one deck decorative layer through one deck tack coat; And avoided to a certain extent decorative layer of the prior art be covered on touch screen surface bonding process, thereby improved the yield of product to a certain extent.

Other characteristics of the utility model and advantage will use following embodiment to combine following accompanying drawing to explain.

Embodiment

Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Embodiment one

Be illustrated in figure 1 as the structural representation of the touch-screen of the utility model embodiment one; Shown in Figure 2 is the structural representation of the decorative layer 11 among the utility model embodiment one; The described touch-screen of Fig. 1; Comprise upper substrate 1, go up transparency conducting layer 2, go up conducting wire 3, go up insulation course 4, tack coat 5, insulation course 6, separation layer 7, conducting wire 8, transparency conducting layer 9 and infrabasal plate 10 down down down; Said upper substrate 1 comprises conductive pattern district 101 and conducting wire district 102, and the said transparency conducting layer 2 of going up is positioned at conductive pattern district 101, also is provided with decorative layer 11 in the conducting wire district 102 of said upper substrate 1 lower surface; Said decorative layer 11 comprises cabling district 111, and said upward conducting wire 3 is arranged at said cabling district 111 and insulate with decorative layer 11.

In the present embodiment; Cabling district 111 uses insulating material; So that make decorative layer 11 and conducting wire 3 electrical isolations; In concrete manufacturing process, can at first transparency conducting layer 2 be set in the conductive pattern district 101 of upper substrate 1 lower surface, in the conducting wire district 102 of upper substrate 1 lower surface decorative layer 11 is set then; At decorative layer 11 lower surfaces conducting wire 3 is set afterwards; With last transparency conducting layer 2 be set to upper substrate 1 method can but be not limited to silk-screen, laser and do quarter, gold-tinted processing procedure etc., this decorative layer 11 be set to upper substrate 1 method can but be not limited to silk-screen, bat printing, spraying, plating etc., in the cabling district 111 of decorative layer 11, be provided with conducting wire 3 method can but be not limited to silk-screen, bat printing, spraying, plating etc.

The touch-screen of the utility model is provided with decorative layer 11 through the conducting wire district 102 at the upper substrate 1 of touch-screen, with decorative layer 11 and the integrated making of touch-screen; Promptly reach the effect of covering conducting wire 3; Saved again in touch screen surface and used double faced adhesive tape to paste the operation of PET decorative layer, reduced production process, improved yields; And make the integral thickness of touch-screen diminish, satisfy the demand of touch-screen slimming.

Embodiment two

Be illustrated in figure 3 as the structural representation of the touch-screen of the utility model embodiment two; Shown in Figure 4 is the structural representation of the decorative layer 11 among the utility model embodiment two; The touch-screen of embodiment two; Be that with the touch-screen difference of embodiment one the cabling district 111 of said decorative layer 11 is for running through the groove of decorative layer 11, the said conducting wire 3 of going up is arranged in the said cabling district 111.

In the present embodiment, there is the gap in the said conducting wire 3 of going up with decorative layer, so that make decorative layer 11 and conducting wire 3 electrical isolations; In order to reach good decorative effect, preferably go up conducting wire 3 and use same material with said decorative layer 11, its color is identical; Preferably, can use plated material, like nickel, aluminium etc.; Decorative layer 11 thickness of its making can be less than 1um, with said decorative layer 11 and last conducting wire 3 be set to upper substrate 1 method can but be not limited to silk-screen, bat printing, spraying, plating, laser and do and carve etc., when specifically making; Can earlier decorative layer 11 be set to upper substrate 1; Because same materials are used with decorative layer 11 in last conducting wire 3, can be directly directly carve conducting wire 3 and cabling district 111 using laser to do method such as quarters on the decorative layer 11, with decorative layer 11 and conducting wire 3 integrated making.

Because conducting wire 3 is the full cabling district 111 of complete filling not, in order to reach better decorative effect, can be coated with the insulating material with said decorative layer same color in the blank space of ornamental area 111, preferably use dielectric ink, its strong adhesion, thickness is little.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
