Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 2 is the structural representation of the touch-screen circuit that the utility model embodiment one provides.As shown in Figure 2, the touch-screen circuit that the present embodiment provides, comprises substrate 20, at least one the first connecting line 21, some second connecting lines 22 and electrostatic protection lines 23;
First connecting line 21, second connecting line 22 and electrostatic protection line 23 are arranged in substrate 20, first connecting line 21 and the second connecting line 22 are all positioned at the shaped interior that electrostatic protection line 23 surrounds, and the first connecting line 21 is in the outside of the second connecting line 22, the live width of the first connecting line 21 is greater than 0.04mm, and the live width of the second connecting line 22 is less than 0.04mm;
First connecting line 21 is all connected with the conductive unit of touch-screen with the second connecting line 22, and for transmitting the electric signal of conductive unit, electrostatic protection line 23 imports the first connecting line 21 and the second connecting line 22 into for preventing electrostatic charge.
Concrete, the substrate 20 of touch-screen circuit can adopt polymetylmethacrylate to make, and the substrate 20 that this material is made is transparence, and has good electrical specification.
Electrostatic protection line 23 is positioned at the outermost of whole touch-screen circuit, and the first connecting line 21 and the second connecting line 22 is surrounded.Like this when touch-screen circuit is subject to the electrostatic interference from the external world; during as Electro-static Driven Comb ESD; electrostatic charge can be guided to other places by electrostatic protection line 23, receives the impact of electrostatic with the first connecting line 21 and the second connecting line 22 that prevent inner side and produces signal interruption phenomenon.
Concrete, electrostatic protection line 23 can be ground wire, and this ground wire one end can be connected with grounding body, thus the static charge in the external world directly can be imported grounding body, and avoids the accumulation of electrostatic charge on touch-screen circuit.
The connecting line of touch-screen circuit can be divided into the first connecting line 21 and the second connecting line 22, first connecting line 21 to be in the outside of the second connecting line 22.First connecting line 21 is different with the second connecting line 22 live width, and other specification, structure and function are all consistent, are all connected with the conductive unit of touch-screen, and for transmitting the electric signal of conductive unit.Such as, the first connecting line 21 and the second connecting line 22 all can be made up of copper-foil conducting electricity, and are printed on substrate 20, in order to carry out the transmission of electric signal.
First connecting line 21 is adjacent with electrostatic protection line 23, and the quantity of the first connecting line 21 is at least one.When touch-screen circuit be subject to extraneous static affect time; extraneous static lotus is first through electrostatic protection line 23; if electrostatic protection line 23 is failed in time by these static charge carrying-offs, partial electrostatic lotus often alters first connecting line 21 and second connecting line 22 of carry inside electrostatic protection line.So the first connecting line 21 should be made to have the ability of enough guiding static charges, in order to avoid the connecting line of inner side is subject to electrostatic influence.
Concrete, the live width Gw1 that can arrange the first connecting line 21 is greater than 0.04mm.This is because the current-carrying capacity of connecting line and the circuit section of connecting line amass relevant, when the sectional area of connecting line is larger, then current-carrying capacity is also larger, and connecting line inherently can bear more electric charge and move, and to be not easy disturb by the electrostatic charge in the external world and interrupt.Preferably, the live width of the first connecting line 21 is between 0.06mm-0.08mm, and live width is that the connecting line of this width had both had comparatively forceful electric power lotus load-bearing capacity, and this live width also can not too increase always taking up room of touch-screen circuit simultaneously.
If first connecting line 21 adjacent with electrostatic protection line can not guide extraneous static charge in time, then static charge will continue to scurry into the connecting line closer to inner side.So the first connecting line 21 can be many, make static charge be fully directed to it by outermost several the first connecting lines 21 like this and locate, thus strengthen the antistatic effect of whole touch-screen circuit.As preferably, the quantity of the first connecting line 21 between 2-4 bar, so both can ensure the antistatic effect of touch-screen circuit, also too can not increase the cabling space (overall width generally only increases within 0.1mm) of touch-screen circuit.
Second connecting line 22 is positioned at the inner side of the first connecting line 21, and the width G w2 of the second connecting line 22 is less than 0.04mm.Because the quantity of the second connecting line 22 is more, so when the second connecting line 22 employing is less than the ultra-fine live width of 0.04mm, the entirety that can reduce touch-screen circuit greatly takes up room, thus ensures that touch-screen has narrower frame.
In the present embodiment, touch-screen circuit comprises substrate, at least one the first connecting lines, some second connecting lines and an electrostatic protection line; First connecting line, the second connecting line and electrostatic protection line are arranged in substrate, first connecting line and the second connecting line are all positioned at the shaped interior that electrostatic protection line surrounds, and the first connecting line is in the outside of the second connecting line, the live width of the first connecting line is greater than 0.04mm, and the live width of the second connecting line is less than 0.04mm; First connecting line is all connected with the conductive unit of touch-screen with the second connecting line, and for transmitting the electric signal of conductive unit, electrostatic protection line is used for preventing electrostatic charge from importing the first connecting line and the second connecting line into.Realizing while the connecting line in touch-screen circuit is fine rule road, makes peripheral connecting line have the ability of enough guiding extraneous static lotuses, being subject to the impact of extraneous static lotus to avoid whole touch-screen circuit like this.
The utility model also provides a kind of touch-screen, comprises conductive unit and touch-screen circuit as above, and wherein the structure of touch-screen circuit, function and effect all can refer to associated description embodiment illustrated in fig. 2, repeat no more herein.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
