CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a 371 U.S. National Stage of International Application No. PCT/CN2011/083438, filed Dec. 5, 2011, and claims priority to Chinese patent application No. 201110383914.7, filed Nov. 28, 2011, the disclosures of which are herein incorporated by reference in their entirety. 
     FIELD OF THE INVENTION 
     The present invention relates to a liquid crystal display (LCD) panel technology, and especially to a repairing line system and a repair method thereof with regard to the LCD panel. 
     BACKGROUND OF THE INVENTION 
       FIG. 1  is a schematic drawing illustrating an LCD panel having a repairing line system in prior art, in which the LCD panel includes a substrate  110 , a driver  120 , four packages  131 ,  132 ,  133  and  134 , and four repairing line  141 ,  142 ,  143  and  144 . The driver  120  inputs signals into data lines  111  for the LCD panel to show corresponding images. 
     The package  131 ,  132 ,  133  and  134  are respectively coupled to the driver  120  and the substrate  110 . Both the repairing line  141  and the repairing line  142  are disposed on both sides of the substrate  110  (i.e., both ends of the data line  111 ) along one side of the substrate  110  sequentially via the packages  131 ,  132  and the driver  120 . The repairing line  143  and the repairing line  144  are disposed on both sides of the substrate  110  along one side of the substrate  110  sequentially via the packages  133 ,  134  and the driver  120 . The repairing line  141  and the repairing line  142  are served as replaceable lines of the data line  111  on the substrate  110 , so that the output signal of the driver  120  can be outputted to the data line  111  via the repairing line  141  and the repairing line  142  when the data line  111  is broken. 
     The repairing line  141  and the repairing line  142  are respectively led from the packages  131 ,  132  in order to repair the data line  111  led from the packages  131 ,  132 . When the data line  111  is broken at “A” point in the drawing, both ends of the broken data line  111  are respectively coupled to “B” and “C” points of the repairing line  141 , whereby the repairing line  141  can replace the broken data line  111  after coupling. 
     However, the repairing line  141  and the repairing line  142  can repair only two broken data lines within the package  131  and the package  132 . That is to say, if there are three broken data lines simultaneously occurring within the package  131  and the package  132 , the repairing line  141  and the repairing line  142  cannot repair the three broken data lines. Those of the package  133  and the package  134  can be repaired through the repairing line  143  and the repairing line  144 , but the repairing line  143  and the repairing line  144  also can repair only two broken data lines within the package  133  and the package  134 . 
     In summary, each package of the conventional repairing line system on the LCD panel can repair only two broken data lines through the repairing lines, and each half LCD panel can repair only two broken data lines through the repairing lines. If above two broken data lines occur in some package, all the broken data lines of the package cannot be repaired. 
     Therefore, there is a significant need to provide a repairing line system and a repair method thereof for solving the problems existing in the prior art.

Ends of the outgoing lines  2411  and  2414  insulatively intersect the first connecting line  251  and the second connecting line  252 , and opposite ends thereof are coupled to the wire  2412  via a signal amplifier  262 . Ends of the outgoing lines  2413  and  2415  insulatively intersect the first connecting line  251  and the second connecting line  252 , and opposite ends thereof are coupled to the wire  2412  via a signal amplifier  263 . 
     The second repairing line  242  includes an outgoing line  2421 , an outgoing line  2423 , an outgoing line  2424 , an outgoing line  2425  and a wire  2422 . The outgoing line  2421 ,  2423 ,  2424 , and  2425  are respectively led from the package  231 ,  233 ,  232 , and  234 , and the wire  2422  is disposed on three sides of the substrate  210  without the packages disposed  231 ,  232 ,  233 , and  234 .

     In the preferred embodiment of the present invention, the repair method of the repairing line system further includes the step of: amplifying data signals of the repairing lines. Because the transmission path of the repairing line is generally longer than the data line awaiting for repair, it is easy to cause signal distortion. The signals are amplified in advance and then are transmitted through the repairing line thereby preventing the signal distortion caused by signal loss along the transmission path. 
     The repairing line system and the repair method of the present invention will now be described in detail with reference to the LCD panel having three and four data lines awaiting for repair. 
     Referring to  FIG. 4 ,  FIG. 4  is a schematic drawing illustrating a repairing line system and a repair method for repairing three data lines awaiting for repair according to the present invention.

     The step  401  specifically comprises: connecting the first connecting line  251  and the outgoing line  2421 , then connecting the first connecting line  251  and the first terminal of the data line awaiting for repair  211 , and connecting the wire  2422  of the second repairing line  242  and the second terminal of the data line awaiting for repair  211 ; connecting the second connecting line  252  and the outgoing line  2411 , then connecting the second connecting line  252  and the first terminal of the data line awaiting for repair  212 , and connecting the wire  2412  of the first repairing line  241  and the second terminal of the data line awaiting for repair  212 ; connecting the first connecting line  251  and the outgoing line  2413 , then connecting the first connecting line  251  and the first terminal of the data line awaiting for repair  213 , and connecting the wire  2412  of the first repairing line  241  and the second terminal of the data line awaiting for repair  213 . 
     The connecting way is by using a laser to fuse an insulative layer between the first and second connecting lines, the outgoing lines, and the data line awaiting for repair for conducting both. 
     Then the step  402  specifically comprises: cutting the first connecting line  251  at “D” point located between a connection point of the first connecting line  251  and the data line awaiting for repair  213  and a connection point of the first connecting line  251  and the data line awaiting for repair  211 ; cutting the first repairing line  241  at “E” point located between a connection point of the first repairing line  241  and the data line awaiting for repair  212  and a connection point of the first repairing line  241  and the data line awaiting for repair  213 . 
     When a data signal is inputted into one end of data line awaiting for repair  211  from the driver  220 , the data signal is transmitted to the connection point of the first connecting line  251  and the outgoing line  2421  after the data signal passing through the connection point of the data line awaiting for repair  211  and the first connecting line  251 . Then the data signal is transmitted to the signal amplifier  261  along the outgoing line  2421 , and the data signal is transmitted to the wire  2422  after being amplified by the signal amplifier  261 . Then the data signal is inputted into the connection point of the data line awaiting for repair  211  and the wire  2422 , thereby realizing the data signal transmission of the data line awaiting for repair  211 . Similarly, the data signal transmission of the data lines awaiting for repair  212 ,  213  also can be realized. 
     From the method described above, two replaceable lines are formed by the first repairing line  241 , and a replaceable line is formed by the second repairing line  242 , thereby realizing the repairs of the data line awaiting for repair  211 , the data line awaiting for repair  212 , and the data line awaiting for repair  213  for the first package  231 . 
     The above-mentioned repairing line system and the repair method can be utilized to realize the repair for the single package having the three data lines awaiting for repair. The single package can be any one of the first package, the second package, the third package, and the fourth package, as long as the connection points between the outgoing lines of the first repairing line  241  as well as the second repairing line  242  led from each package and the first connecting line  251  as well as the second connecting line  252  are changed. 
       FIG. 5  is a schematic drawing illustrating the repairing line system and the repair method for repairing four data lines awaiting for repair according to the present invention. When the data line awaiting for repair  211 , the data line awaiting for repair  212 , the data line awaiting for repair  213 , and the data line awaiting for repair  214  exist on the substrate  210 . 
     The step  401  specifically comprises: connecting the first connecting line  251  and the outgoing line  2421 , then connecting the first connecting line  251  and the first terminal of the data line awaiting for repair  211 , and connecting the wire  2422  of the second repairing line  242  and the second terminal of the data line awaiting for repair  211 ; connecting the second connecting line  252  and the outgoing line  2411 , then connecting the second connecting line  252  and the first terminal of the data line awaiting for repair  212 , and connecting the wire  2412  of the first repairing line  241  and the second terminal of the data line awaiting for repair  212 ; connecting the first connecting line  251  and the outgoing line  2413 , then connecting the first connecting line  251  and the first terminal of the data line awaiting for repair  213 , and connecting the wire  2412  of the first repairing line  241  and the second terminal of the data line awaiting for repair  213 ; connecting the second connecting line  252  and the outgoing line  2423 , then connecting the second connecting line  252  and the first terminal of the data line awaiting for repair  214 , and connecting the wire  2422  of the second repairing line  242  and the second terminal of the data line awaiting for repair  214 . 
     The connecting way is by using the laser to fuse an insulative layer between the first and second connecting lines, the outgoing lines, and the data line awaiting for repair for conducting both. 
     Then the step  402  specifically comprises: cutting the first connecting line  251  at “D” point located between the connection point of the first connecting line  251  and the data line awaiting for repair  213  and the connection point of the first connecting line  251  and the data line awaiting for repair  211 ; cutting the first repairing line  241  at “E” point located between the connection point of the first repairing line  241  and the data line awaiting for repair  212  and the connection point of the first repairing line  241  and the data line awaiting for repair  213 ; cutting the second connecting line  252  at “F” point located between a connection point of the second connecting line  252  and the data line awaiting for repair  212  and a connection point of the second connecting line  252  and the data line awaiting for repair  214 ; cutting the second repairing line  242  at “G” point located between a connection point of the second repairing line  242  and the data line awaiting for repair  211  and a connection point of the second repairing line  242  and the data line awaiting for repair  214 . 
     When a data signal is inputted into one end of data line awaiting for repair  211  from the driver  220 , the data signal is transmitted to the connection point of the first connecting line  251  and the outgoing line  2421  after the data signal passing through the connection point of the data line awaiting for repair  211  and the first connecting line  251 . Then the data signal is transmitted to the signal amplifier  261  along the outgoing line  2421 , and the data signal is transmitted to the wire  2422  after being amplified by the signal amplifier  261 . Then the data signal is inputted into the connection point of the data line awaiting for repair  211  and the wire  2422 , thereby realizing the data signal transmission of the data line awaiting for repair  211 . Similarly, the data signal transmission of the data lines awaiting for repair  212 ,  213  and  214  also can be realized. 
     Accordingly, two replaceable lines are formed by the first repairing line  241 , and two replaceable lines are formed by the second repairing line  242 , thereby realizing the repairs of the data line awaiting for repair  211 , the data line awaiting for repair  212 , the data line awaiting for repair  213 , and the data line awaiting for repair  214 . 
     Because of the connecting lines which insulatively intersect the data lines and the repairing lines in the present invention, when the data line is broken, the first terminals of the outgoing line and the data line awaiting for repair of the repairing line corresponding to the package are respectively coupled to the connecting line. Meanwhile, the wire of the corresponding repairing line is coupled to the second terminal of the data line awaiting for repair forming the replaceable lines thereby replacing the data lines awaiting for repair to perform the signal communication. Therefore, the multiple broken data lines occurring in the single package can be repaired.
