Abstract
The present invention relates to a repairable GOA drive system, a driving method for a GOA circuit, and a display panel, which are used to improve the yield of display panels in a manufacturing process. The display panel includes a display area and a pixel circuit arranged in the display area, and the repairable GOA drive system includes a GOA circuit, a repair circuit, and a driver IC. The GOA circuit is connected to a driving signal output end of the driver IC; and the repair circuit is arranged between the driver IC and the pixel circuit and configured to replace at least one abnormal GOA unit in the GOA circuit to output a driving signal to the corresponding pixel circuit when the at least one GOA unit is abnormal. The implementation of the present invention can greatly improve repairability of backplane circuits with a GOA and increase the screen yield in mass production.
