Outer signals are shielded, and then are further ensured that touch-screen is not disturbed by outer signals.
It should be noted that Fig. 4 of the application is into Fig. 6, black portions represent the material of the part have been removed or
Person does not have inherently, and white portion represents that the part has corresponding material (lead material either senses layer material).Wherein,
In Fig. 4 to 6, because the density of lead is larger and lead is thinner so that the quilt in the first wire portion 01 and/or the second wire portion 04
The region of removal looks like what is joined together, but actually really not so, can be clearly seen that if figure amplification
All it is that tool is spaced between adjacent lead or ground wire, i.e., black portions can't join together.
As can be seen from the above description, the application the above embodiments realize following technique effect：
1), the printing screen plate of the application, due to, simultaneously including first line area and the second line areas, being adopted in the printing screen plate
Just can be respectively on the first inductive layer with forming the first leading part and the second leading part on the second inductive layer with the half tone, its
In, the first leading part and the second leading part include conductive part and ground wire portion.When forming the first leading part, first line area is extremely
It is correspondingly formed wire portion therein less, the second line areas is correspondingly formed at least part ground wire portion therein, first line area and the
Two line areas can just form the first leading part；When forming the second leading part, the second line areas is at least correspondingly formed therein
Wire portion, first line area is correspondingly formed at least part ground wire portion, and first line area can just form second with the second line areas
Leading part.The invention of the half tone so that two printing screen plates need not be used when forming the first leading part and the second leading part, only
Need the printing screen plate just to form the first leading part and the second leading part respectively, reduce being fabricated to for touch-screen
This, improves its producing efficiency.
2), the preparation method efficiency of the touch-screen of the application is higher, and cost is relatively low.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent substitution, improvement etc., should be included within the protection domain of the application.
