Case static electricity shield layer 124 comprises multiple first bus 1241 and multiple second bus 1242 is interlaced multiple to be formed
Opening 124a, each bar bridging line 122 is positioned among the one of which of multiple opening 124a.
It should be noted that in subsequent step, insulating barrier and the second conductive layer will be sequentially formed in the first conductive layer 120
On, therefore patterning static electricity shield layer 124, insulating barrier and the second conductive layer may make up a capacitance structure.This capacitance structure contributes to
Reduce the voltage that static discharge is caused so that it is be difficult to reach avalanche voltage value, therefore electrostatic discharges contact panel can be avoided
In element.This principle will be in following middle detailed description.In reality is applied, bridging line 122 and patterning static electricity shield layer 124
Configuration mode can make other suitable change, so that patterning static electricity shield layer 124, insulating barrier and the second conductive layer constitute electricity
Hold structure, therefore its configuration mode is not limited to illustrated in Fig. 1.
Fig. 2 A is the upper schematic diagram of the insulating barrier 130 illustrating present embodiment.Fig. 2 B is to illustrate the line segment 2B-along Fig. 2 A
The generalized section of 2B '.The material of insulating barrier 130 can be inorganic insulating material, as silica, silicon nitride, silicon oxynitride or its
Its suitable material.Insulating barrier 130 has at least two contact hole 130a, each contact hole 130a and exposes the bridging line of a part
122.With generally speaking, insulating barrier 130 can have multiple contact hole 130a, and each bar bridging line 122 can arrange four contact holes
130a.But insulating barrier 130 is in order to expose the bridging line 122 of a part, and makes patterning static electricity shield layer 124 and be subsequently formed
It is electrically insulated between second conductive layer, therefore in reality is applied, the configuration mode of insulating barrier 130 can make suitable change, and not
It is limited to illustrated in Fig. 2 A.
Fig. 3 A is the upper schematic diagram of the second conductive layer 140 illustrating present embodiment.Fig. 3 B is to illustrate the line along Fig. 3 A
The generalized section of section 3B-3B '.Second conductive layer 140 is arranged on the first conductive layer 120, and insulating barrier 130 is located in first and leads
Between electric layer 120 and the second conductive layer 140；Namely second conductive layer 140 be arranged on insulating barrier 130.Second conductive layer 140 can
Made by transparent conductive material, it refers to material illustrated in the embodiment of the first conductive layer 120.Second conductive layer
140 comprise the first sensing serial 142 and at least two sensor pad 144.First sensing serial 142 comprises at least one bridging line
1422 and multiple sensor pad 1424.Bridging line 1422 concatenates two adjacent sensor pads 1424, to form the first sensing serial
142.Two sensor pads 144 lay respectively at the opposite sides of the first sensing serial 142.As shown in Figure 3 B, bridging line 122 is by two
Individual contact hole 130a connects adjacent two sensor pad 144 respectively, to form the second sensing serial 146 shown in Fig. 3 A.
With generally speaking, the second conductive layer 140 can comprise multiple first sensing serial 142 and multiple sensing separated from one another
Pad 144.Sensor pad 1424 and the sensor pad 144 of the first sensing serial 142 offsets one from another and arranges and underlapped.Sensor pad 1424 with
The shape of sensor pad 144 can be rhombus, square or other can the shape of aligned transfer.Each bar bridging line 122 concatenates two
Adjacent sensor pad 144, to form multiple second sensing serial 146.Therefore, as shown in Figure 3A, multiple first sensing serials 142
Extend and interlaced towards first direction D1 and second direction D2 respectively with multiple second sensing serials 146, and constitute a touch-control
Pattern array.
It should be noted that patterning static electricity shield layer 124 is at least with the part of one of which for two sensor pads 144
Overlap, as shown in Fig. 3 A-Fig. 3 B.In other words, patterning static electricity shield layer 124, insulating barrier 130 and sensor pad 144 are along thickness
Direction storehouse and constitute a capacitance structure.This capacitance structure contributes to reducing the voltage that static discharge is caused so that it is be difficult to reach
To avalanche voltage value, and the element in electrostatic breakdown contact panel 100 can be avoided.This principle is described below in detail.It is said that in general,
Only comprise the first sensing serial 142, insulating barrier 130 and the second sensing serial 146 at contact panel, and do not comprise patterning electrostatic
In the case of overcoat 124, when static discharge phenomenon occurs, the voltage that element is born can be calculated by following formula (1) and obtain:
V1=Q/C1............................... formula (1)
Wherein, the voltage that V1 is born by element, Q is external electric charge, C1 be the first sensing serial 142, insulating barrier 130 and
The capacitance that second sensing serial 146 is constituted.In the present embodiment, the voltage that element is born can be by following formula (2) calculating
:
V2=Q/ (C1+C2) ... ... ... ... .. formula (2)
Wherein, the voltage that V2 is born by element, Q is external electric charge, C1 be the first sensing serial 142, insulating barrier 130 and
The capacitance that second sensing serial 146 is constituted, C2 is constituted for patterning static electricity shield layer 124, insulating barrier 130 and sensor pad 144
Capacitance.Therefore, when external charge value (i.e. Q value) is identical, voltage V2 can be lower than voltage V1, and is less susceptible to reach snowslide electricity
Pressure value, therefore the element that can be prevented effectively from contact panel 100 damages because of electrostatic.
In order to understand the effect of patterning static electricity shield layer 124, inventor tests respectively and does not comprises patterning electrostatic defending
The contact panel of layer 124 and the avalanche voltage value of contact panel 100.Do not comprise the contact panel of patterning static electricity shield layer 124
Only comprising the first sensing serial 142, insulating barrier 130 and the second sensing serial 146, the avalanche voltage value of this contact panel is
2.5kV.Contact panel 100 comprises patterning static electricity shield layer 124, insulating barrier 130, first senses serial 142 and the second sensing
Serial 146, the avalanche voltage value of this contact panel 100 is 6.0kV.It follows that present embodiment can actually effectively promote
The antistatic capacity of contact panel.
