Abstract: A method for repairing the gate-line disconnection includes: determining a disconnected position of a gate line; determining two connecting elements that are closest to the disconnected position and are respectively located at two sides of the disconnected position along an extending direction of the gate line; selecting one or two sub-pixels electrically connected to the two connecting elements as repair sub-pixels, determining a common electrode line coupled to a common electrode of each repair sub-pixel as a selected common electrode line; forming a communication path between a front portion and a rear portion at the disconnected position to bypass the disconnected position, the communication path including at least the common electrode of each repair sub-pixel and a separate line segment cut from the selected common electrode line; disconnecting the common electrode in the communication path from other common electrodes; and disconnecting each repair sub-pixel from a data line.
