The object of the invention to solve the technical problems also can be used following technical measures and further realize.
Specifically, as shown in Figure 2 and Figure 4, the conducting wire includes the first conducting wire 1 and the second conducting wire 2, first conducting wire 1
On be connected with the signal input part 23, the signal output end 24, first conducting wire 1 are connected on second conducting wire 2
It is set side by side with second conducting wire 2 and is arranged along the edge of the panel body 1, the detecting element 22 includes input terminal
And output end, the input terminal are connected to first conducting wire 1, the output end is connected to second conducting wire 2.Such as Fig. 2 and
Described shown in Fig. 4, the input terminal of detecting element 22 is connected on the first conducting wire 1, and output terminates on the second conducting wire 2, Jin Erneng
Enough so that each detecting element 22 is in parallel, wherein the first conducting wire 1 and the second conducting wire 2 are arranged along the edge of panel body 1, but
It is that there is a certain distance apart from edge.The head end of first conducting wire 1 is not attached to end, it is believed that the setting of the first conducting wire 1
Have signal input part 23 one end be head end, and be not provided with signal input part 23 end can open circuit, can also be located at
The input terminal of the detecting element 22 of tail end is connected.And one end of signal output end 24 is not provided on the second conducting wire 2 to break
Road can also be connected with the output end for the detecting element 22 for being located at 2 end of the second conducting wire.At this point, multiple detecting elements 22 can
The first conducting wire 1 is divided into multistage, when being provided with eight detecting elements 22, detecting element 22 can be by the first conducting wire 1 and
Two conducting wires 2 are divided into eight sections, this eight section lead is followed successively by the 8th section of first segment, second segment ..., as shown in Figure 3 and Figure 5, Fig. 3 with
It is respectively first segment on the first conducting wire to the 8th section that Fig. 5 acceptance of the bid, which has the conducting wire of serial number 1., 2., 3., 4., 5., 6., 7., 8., the
Conducting wire corresponding with the first fragment position of the first conducting wire is the with the first conducting wire on the second conducting wire of first segment ... on two conducting wires
The corresponding conducting wire of eight fragment positions is the 8th section, and along each of the direction of the tail end of the head end of the first conducting wire 1 the first conducting wire 1 of direction
Detecting element 22 is followed successively by the first detecting element, the 8th detecting element of the second detecting element ....When third section lead breaks
When splitting, the first detecting element, the second detecting element and third detecting element have access to signal input part 23 and signal output
Between end 24, three detecting elements are accessed in the electrical information and circuit that signal input part 23 and signal output end 24 detect
22 electrical information matches.Wherein, in order to guarantee effectively to detect crackle, at least guarantee that a conducting wire closes on panel master
The edge of body 1, when crackle occurs, at least a conducting wire can be broken.
Specifically, as shown in Fig. 2, first conducting wire 1 is provided with one end and described second of the signal input part 23
One end that conducting wire 2 is provided with the signal output end 24 is adjacent.Signal input part 23 is adjacent with signal output end 24, such as Fig. 2 institute
Show, end 23 can be input a signal into and signal output end 24 is arranged at the left side of panel body 1, at this point, the electricity of detection unit
Road figure is as shown in figure 3, when the third section of the first conducting wire 1 and the second conducting wire 2 is broken, letter that signal input part 23 inputs
Number still can spread out of from signal output end 24, i.e., at this time still can pass through signal input part 23 and signal output end 24 detection
It is linked into the electrical information of the detecting element 22 in circuit.When a certain section of hair of any of the first conducting wire 1 and the second conducting wire 2
When raw fracture, it can normally detect crackle and generate position.
Specifically, as shown in Fig. 2, first conducting wire 1 is set around the panel body for 1 one weeks with second conducting wire 2
It sets, 2 area defined of the second conducting wire is placed in the area defined of first conducting wire 1.First conducting wire 1 and second

When, signal output end 24 is set to the position that 1 end of the first conducting wire is closed on the second conducting wire 2, at this point, the circuit diagram of detection unit
As shown in figure 4, signal input part 23 and signal output end can be passed through at this time when being broken for the 4th section of the first conducting wire 1
The number for the detecting element 22 that 24 detections access therebetween, and then judge the position cracked.But when the first conducting wire
1 and second the 4th section of conducting wire 2 when being broken, the detection signal inputted from signal input part 23 just cannot be transferred to signal
Output end 24, at this point, can't detect electrical information between the two.But when detecting element 22 is capacitor, inspection can be passed through
Slowdown monitoring circuit from capacitance, in order to obtain the capacitance between signal input part 23 and fracture position, judge to occur with this disconnected
The position split judges the position that crackle generates.There are low level electric current of voltage regulation to input (VSS) in the peripheral region of display panel
Region can detect the capacitance between signal input part 23 and the region VSS, at this point it is possible to by signal when detection is from capacitance
Output end 24 is arranged in the region VSS.
Specifically, as shown in Figures 2 to 5, the detecting element 22 is capacitor.Detecting element 22 is preferably capacitor, each
Link in parallel, presets in detection unit and eight capacitors is arranged altogether between capacitor, at this point, the total capacitance value of eight capacitors is each electricity
The sum of capacitance of appearance.Wherein it is possible to make the capacitance of each capacitor equal, the detection in access circuit is being detected in this way
After the total capacitance value of element 22, make total capacitance value divided by the capacitance of each capacitor, just can be derived that crackle results from conducting wire
Which section, facilitate testing staff to calculate.The edge of panel body 1 can be uniformly arranged in each capacitor.Into
When row capacitance detects, by 23 input AC electric signal of signal input part, ac signal can pass through capacitive transmission to signal
Output end 24, and then it is able to carry out the detection of capacitor.As shown in Figure 2 and Figure 4, shown, the first conducting wire 1 is compared and the second conducting wire 2
Edge apart from panel body 1 is closer, by taking the first conducting wire 1 as an example, as shown in Figure 2 and Figure 5, first capacitor 221 and the second capacitor
Between conducting wire be first segment, conducting wire between the second capacitor and third capacitor is second segment, and so on, the 7th capacitor and the
Conducting wire between eight capacitors 222 is the 7th section, and the conducting wire between signal input part 23 and first capacitor 221 is the 8th section, the
One conducting wire 1 and the second conducting wire 2 are Cm=C1+C2+C3+C4+C5+C6+C7+ there is no the total capacitance value in circuit when fracture
C8, wherein C1 ... C8 refers respectively to the capacitance of 221 to the 8th capacitor 222 of first capacitor, when the 8th section lead breaks
When splitting, capacitor Cm between signal input part 23 and signal output end 24 is 0, at this point, be linked into circuit without capacitor, when the
When one section lead is broken, the capacitance detected is the capacitance of first capacitor 221, when second segment is broken,
It is linked into circuit there are two capacitor, the total capacitance being linked into circuit at this time is first capacitor 221 and the second capacitor
The sum of capacitance Cm=C1+C2, i.e.,.And so on, when being broken for the 7th section of the first conducting wire 1, Cm=C1+C2+C3+C4
+C5+C6+C7。
