Claim:
1. A method for detecting disconnection of a plurality of gate lines; two ends of each of the gate lines are connected to a first detection line and a second detection line, respectively, so as to form a short-circuited structure, and the gate lines being provided in multiple rows; the method comprising: step 1: providing a first unit at one end of a gate line to be detected, the first unit being at least capable of receiving signals from the gate line to be detected; and providing a second unit at the other end of the gate line to be detected, the second unit being at least capable of transmitting signals to the gate line to be detected; step 2: providing a first signal receiving unit on a gate line other than the gate line to be detected, the first signal receiving unit being capable of receiving signals from the second unit; after the step 2, the method further includes: step 3: judging whether or not the signal strength received by the first signal receiving unit is larger than a preset value; if so, then it is judged that disconnection occurs to the gate line to be detected.
