Abstract: The present disclosure provides a circuit and method for repairing signal line disconnection and a display panel associated therewith. The circuit comprises a signal analysis module, a first control module and a second control module. The signal analysis module detects signals at a first and second node of a first signal line, and outputs a control signal at its output under control of the signals at the first and second node. Under control of the control signal, the first control module conductively connects the first node of a first signal line with a first node of a second signal line, and the second control module conductively connects the second node of the first signal line with a second node of the second signal line. The present disclosure may be applied to manufacturing of displays, which solves the problem that existing approaches for repairing signal line disconnection are time-consuming and low-efficiency.
