A wiring structure of a wiring area on a liquid crystal displaying panel includes a number of wiring lines connected to one end of a corresponding data line and corresponding scan line on the wiring area, at least one signal testing point, a number of first testing lines connected between the wiring lines and the signal testing point, a number of second testing lines connected between the signal testing point and the other end of the corresponding data line and the corresponding scan line, and a switch controlling circuit connected to the second testing lines. After the testing lines are disconnected from the wiring lines in the previous process, the testing signal still can be transmitted through the other end of the corresponding data line or the scan line, to implement the image test of the liquid crystal displaying panel. |

1. A wiring structure of a wiring area on a liquid crystal displaying panel, comprising:
a plurality of wiring lines respectively connected to one end of a corresponding data line and one end of a corresponding scan line; at least one signal testing point, configured to receive at least one testing signal for testing the liquid crystal displaying panel; a plurality of first testing lines connected between the wiring lines and the at least one signal testing point; a plurality of second testing lines connected between the at least one signal testing point and the other end of the corresponding data line and the corresponding scan line; and a switch controlling circuit connected to the second testing lines, configured to control the path of the at least one testing signal from the at least one signal testing point to the display area of the liquid crystal displaying panel; wherein each signal testing point comprises a first signal testing point and a second signal testing point, one end of the first signal testing point is connected to the wiring line of the corresponding data line through the first testing line, and the other end thereof is connected to the other end of the corresponding data line through the second testing line, one end of the second signal testing point is connected to the wiring line of the corresponding scan line through the first testing line, and the other end thereof is connected to the other end of the corresponding scan line through the second testing line; wherein the switch controlling circuit comprises electronic switches connected between the second testing lines and the data lines or scan lines, and a controlling signal input point for turning on and off the electronic switches, the controlling signal input point is connected to the electronic switches via a switch controlling bus; when the first testing lines are connected to the wiring lines, the controlling signal input point receives a low-level signal for turning off the corresponding electronic switches, the testing signal is transmitted through the signal testing point, the first testing lines, the corresponding wiring line, and one end of the corresponding data line or scan line in that order to the display area; when the first testing lines are disconnected from the wiring lines, the controlling signal input point receives a high-level signal for turning on the corresponding electronic switch, the testing signal is input from the signal testing point, and transmitted through the second testing lines, the corresponding electronic switch, and the other end of the corresponding data line or scan line in that order to the display area. |
