Abstract
The present invention discloses a rescue circuit of display panel and a rescue method thereof. The rescue circuit includes an amplifier, a first conductive line, a second conductive line, and a third conductive line. The amplifier has an input end and an output end. The first conductive line and the second conductive line intersect and are isolated from signal input terminals of the plurality of signal lines. The first conductive line is electrically connected to the input end and the second conductive line is electrically connected through an electrical resistor to the output end. The third conductive line intersects and is isolated from signal distal ends of the signal lines and is electrically connected to the output end. The rescue method includes performing a welding operation and performing a cutting operation. With such a rescue, a broken signal line may effectively overcome the problem of weak line with the electrical resistor connected to the second conductive line.
