LIQUID CRYSTAL DISPLAY, ARRAY SUBSTRATE OF LIQUID CRYSTAL DISPLAY AND METHOD FOR REPAIRING BROKEN LINE

摘要

The present invention relates to a liquid crystal display, an array substrate of a liquid crystal display and a method for repairing a broken line. A detection line and a repair line are arranged on the array substrate of the liquid crystal display, the detection line is connected to a non-defective scanning line, the repair line is connected to the broken line, and a repair IC outputs a repair signal at an appropriate time after the detection line detects a scanning signal, then the repair line repairs the broken line. The liquid crystal display and the method for repairing a broken line proposed in the present invention can repair the broken line of a scanning line detected by the liquid crystal display after the vacuum align process, reducing the defect rate of the product, avoiding major waste and lowering the production costs.
