In FIG. 1 , the repair circuit of the liquid crystal display panel includes at least: a surround, a line 100, a plurality of strips 102, a plurality of scan lines 1〇4, a data line breakpoint (data iine open) 106, and a plurality of pieces of data. Line repair line 1〇8, amplifier ιι〇 and pre-repair point 112 ° It should be noted that the pre-patching, point 112 is located on the LCD panel, and any one of the plurality of data lines 1〇2 overlaps with the surrounding line 100. region. In general, the pre-repair point 112 is located in a partially overlapping area of the two, but the data line 102 is electrically insulated from the ring and the % line 100, and only when the laser is melted at the pre-repair point 112, the bead line 1〇 Any one of the two is electrically connected to the surrounding line 100.裒, % line 1 〇 〇 surrounds the liquid crystal display panel, and the floating insulation is partially overlapped and electrically insulated from the data line repair line 108 at one end of the plurality of data lines 102. In addition, the data line repair m 9 201124767 line 108 floating insulation traverses one of the other data lines 102 of the other data line 102 corresponding to the data line 1 〇 2, when an electrical fault occurs: over the refining and surrounding line (10) and The partial weight most area 114' of the data line repairing line 1G8 causes the data line repairing line 1〇8 to replace the defective data line 2: 妾: under-displays the pixel voltage of the unit' and displays an image. When the data line with the breakpoint (10) passes through the data line (4) line (10), the flow direction of the repair circuit is indicated by the arrow according to Fig. 1: the data line with the breakpoint (10) is first connected to the data through the connection point ι6. The wire repairing line 108, and then the data line repairing line (10) is electrically connected to the surrounding line 100 by a partial overlapping area 114 of the data line repairing line (10). The above-mentioned electrical connection may be performed by laser welding. The surround line can further include an amplifier ιι, so that the signal is transmitted to the other end of the data line having the breakpoint 106 via the data line repair line 1G8 and the surround line (10), so that the signal is not excessively attenuated. Finally, the surrounding line 100 is electrically connected to the other end of the data line having the broken point (10) through the pre-fixed point 112 connected by the lightning (four) to realize the repair function of the data line. As can be seen from the above description, in the prior art liquid crystal display panel, if a defective data line appears, the normal image display can be realized by the loop winding and the data line repairing line which surround the outer edge of the panel. However, the repair circuit of the display panel only solves the problem of signal transmission when the f-line is electrically faulty, but does not involve the repair of the defective scan line. In this way, if the liquid crystal display panel is electrically disconnected from the scan film through the scan line to the thin film transistor at the pixel, the repair circuit on the board cannot be solved. In order to solve the technical defects appearing in the liquid crystal display panel as shown in FIG. 1 , FIG. 2 is a schematic view showing the structure of a liquid crystal display panel having a data line repair line and a scan line repair line according to an embodiment of the present invention. . The repair circuit on the liquid crystal display panel of Fig. 2 can not only repair the data lines on the glass substrate, but also repair the scan lines on the glass substrate. • In more detail, the repair circuit of the liquid crystal display panel in the figure 2 includes at least: a surrounding line 200, a plurality of data lines 2〇2, a plurality of scanning lines 4, a plurality of data line repairing lines 206, and a connecting line 208. The operational amplifier 210, the switching element 212, and the plurality of scanning line repair lines 2丨4. The surrounding line 200 surrounds the liquid crystal display panel, and the floating insulation spans one end of the plurality of data lines 202, and a portion of the surrounding lines 2〇〇 partially overlaps and is electrically insulated from the plurality of scanning line repair lines 214. In addition, one end of the connecting line 208 partially overlaps the data line repairing line 2〇6 and is electrically insulated, and the other end of the connecting line 208 is electrically connected to the switching unit 212.

The second amplifier is used to electrically connect the surround line 2〇〇 And switch meta #212. When the repair circuit performs a repair operation to eliminate electrical defects on the data, the connection line 208 is electrically connected to the positive input of the first amplifier (indicated by the symbol "+"), and the output of the first amplifier (with the symbol) "-" mark) is electrically connected to the surround line 2GG through the switching element 212; similarly, when the repair circuit performs a repair operation to eliminate an electrical defect on the scan line, one end of the surround line 2〇〇 is switched by the switch τ The first input of the second amplifier is marked with a "+" sign, and the output of the second amplifier (indicated by the symbol) is electrically connected to the other end of the surround line 2〇〇. As can be seen from the above, the switching element 212 in Fig. 2 is an important component for repairing the scan 12 201124767 or the feed line. That is to say, the switching element can be electrically connected to the surrounding line and the scanning line repairing line, or can be electrically connected to the winding line and the data line. In order to more clearly describe the structure of the plant, the third figure is a schematic diagram of the positional relationship between the switching elements of the second embodiment, the second conductive layer, and the welded conductive layer. In the figures 30 and 3, the 'switching element 212 includes at least a conductive layer 430, a rim edge layer 32, and a metal layer electrically connected to the core winding end. Electrical layer 36 and second conductive layer 38. Wherein, one end of the first guiding and connecting lines is electrically connected, and the other end of the second conductive layer 38 and the clothing line, and the other end of the line are abandoned. + Park Road Thread: In one embodiment, the second potential layer 36 is further connected between the second conductive layer 36, wherein the positive input terminal of the amplification H is electrically connected to the one potential of the connection line. The output end of the amplifier is electrically connected to the first conductive layer, and the second conductive layer 38 is electrically connected to the second conductive layer 38. The output of the potential amplification state should be understood.

Moreover, when the laser pre-patching points 3〇〇 and 3〇4, the repair circuit of the crystal display panel is used to repair the electrical fault on the scan line. When the laser pre-patching points are 3〇2 and 3〇6, the repair circuit of the liquid crystal display panel is used to repair electrical faults on the data line. It should also be understood by those skilled in the art that when the laser welding pre-repair points 3〇2 and 306, the end of the surrounding line electrically connected to the metal layer 34 has been electrically connected to the data line repairing line. The laser pre-repair points 3GG and 3G4 should no longer be welded. This is because the % of the dissolved conductive layer can only be electrically connected to the data line repair line or the scan line repair line at the same time. 201124767 In order to explain the circuit flow of repair and scan line repair in the liquid crystal display panel, the second picture:: Line data: Repair on the liquid crystal display panel: No 2nd sniper is still used to repair The return line on the data line 2: The second picture shows the liquid crystal display surface in Fig. 2; Fig.; the schematic diagram of the loop direction of the complementary scan line.
