Abstract: A detecting method and a detecting apparatus for detection of a gate line disconnection. The gate line disconnection detecting method includes step 1: providing a first unit (41) at least capable of receiving signals at one end of a gate line to be detected (2), and providing a second unit (42) at least capable of transmitting signals at the other end of it; step 2: providing a first signal receiving unit (51) for receiving signals on a gate line other than the gate line to be detected (2). With respect to the gate line disconnection detecting method, whether disconnection occurs or not is judged depending on the signal strength received by the first signal receiving unit (51), and thus, the case that in a gate line disconnection detection of a bilateral drive type display device, whether a gate line is disconnected or not can be accurately detected, is realized. By it, technical supports are provided for getting rid of bad products timely, and a goal of promoting the yield of products is achieved.
