Fig. 3 A be illustrate present embodiment the second conductive layer 140 on look schematic diagram.Fig. 3 B is the diagrammatic cross-section illustrating along the line segment 3B-3B ' of Fig. 3 A.The second conductive layer 140 is arranged on the first conductive layer 120, and insulation course 130 is located between the first conductive layer 120 and the second conductive layer 140; Also the second conductive layer 140 is arranged on insulation course 130.The second conductive layer 140 can be made by transparent conductive material, its can the embodiment with reference to the first conductive layer 120 in illustrated material.The second conductive layer 140 comprises the first sensing serial 142 and at least two sensor pads 144.The first sensing serial 142 comprises at least one bridging line 1422 and a plurality of sensor pad 1424.Two adjacent sensor pads 1424 of bridging line 1422 serial connections, to form the first sensing serial 142.Two sensor pads 144 lay respectively at the relative both sides of the first sensing serial 142.As shown in Figure 3 B, bridging line 122 connects respectively two adjacent sensor pads 144 by two contact hole 130a, to form the second sensing serial 146 shown in Fig. 3 A.
With generally speaking, the second conductive layer 140 can comprise a plurality of the first sensing serial 142 and a plurality of sensor pads 144 separated from one another.The sensor pad 1424 of the first sensing serial 142 and sensor pad 144 stagger each other and arrange and underlapped.The shape of sensor pad 1424 and sensor pad 144 can be the shape that rhombus, square or other can rule arrangements.Two adjacent sensor pads 144 of each bridging line 122 serial connections, to form a plurality of the second sensing serials 146.Therefore, as shown in Figure 3A, a plurality of the first sensing serials 142 and a plurality of the second sensing serials 146 are extended and interlaced towards first direction D1 and second direction D2 respectively, and form a touch pattern array.
It should be noted that patterning static electricity shield layer 124 is at least overlapping with a part for the wherein one of two sensor pads 144, as shown in Fig. 3 A-Fig. 3 B.In other words, patterning static electricity shield layer 124, insulation course 130 and sensor pad 144 form a capacitance structure along thickness direction storehouse.This capacitance structure contributes to reduce the voltage that static discharge causes, and makes it be difficult for reaching avalanche voltage value, and can avoid the element in electrostatic breakdown contact panel 100.This principle describes in detail as follows.Generally speaking, at contact panel, only comprise the first sensing serial 142, insulation course 130 and the second sensing serial 146, and in the situation that does not comprise patterning static electricity shield layer 124, when static discharge phenomenon occurs, the voltage that element bears can be calculated and be obtained by following formula (1):
V1=Q/C1................................................. ... ... ... ... ... ... ... .... formula (1)
Wherein, V1 is the voltage that element bears, and Q is external electric charge, and C1 is the capacitance that the first sensing serial 142, insulation course 130 and the second sensing serial 146 form.In the present embodiment, the voltage that element bears can be calculated and be obtained by following formula (2):
V2=Q/ (C1+C2) ... ... ... ... ... ... ... ... ... ... ... ... ... ... .... formula (2)
Wherein, V2 is the voltage that element bears, and Q is external electric charge, and C1 is the capacitance that the first sensing serial 142, insulation course 130 and the second sensing serial 146 form, and C2 is the capacitance that patterning static electricity shield layer 124, insulation course 130 and sensor pad 144 form.Therefore, when external charge value (being Q value) is identical, voltage V2 can be lower than voltage V1, and be difficult for reaching avalanche voltage value, therefore can effectively avoid element in contact panel 100 to damage because of static.
In order to understand the effect of patterning static electricity shield layer 124, inventor tests respectively the contact panel that do not comprise patterning static electricity shield layer 124 and the avalanche voltage value of contact panel 100.The contact panel that does not comprise patterning static electricity shield layer 124 only comprises the first sensing serial 142, insulation course 130 and the second sensing serial 146, and the avalanche voltage value of this contact panel is 2.5kV.Contact panel 100 comprises patterning static electricity shield layer 124, insulation course 130, the first sensing serial 142 and the second sensing serial 146, and the avalanche voltage value of this contact panel 100 is 6.0kV.Hence one can see that, and present embodiment can effectively promote the antistatic capacity of contact panel really.
