Abstract

The present invention provides a method for repairing array substrates, comprising: dividing the array substrates to be repaired into two groups; using a laser repairing unit to identify the positions of the defects of the first group of array substrates and repair point defects; The second group of array substrates is repaired by the laser long-line unit; the array substrates of the first group of array substrates that have been repaired by the laser repair unit and have line defects are transported to the laser long-line unit for repair; When the defects of all the array substrates in the second group of array substrates are found and repaired, the array substrates repaired by the laser long-line unit are transported to the centralized processing machine for centralized processing; All the array substrates at the machine platform are transported to the sorting machine platform, and the repaired array substrates and the array substrates to be repaired are sorted and sorted at the sorting machine platform.

Description

technical field [0001] The present invention relates to the technical field of display panel manufacturing, in particular to an array substrate repair method and a repair device. Background technique [0002] With the development of society, people's demand for display equipment is increasing, and the current production capacity can no longer meet the existing market demand. How to effectively increase production capacity without affecting the yield rate has become an important issue. [0003] During the production process of array substrates, laser repair stations are generally set up in the production line, which can intercept and repair abnormal array substrates in a timely manner, thereby improving the yield rate of finished products. In the existing repair technology, the laser repair machine (Final Laser Repair, FLR) is usually used to display the corresponding defect position of the array substrate on the repair interface of the machine section. The personnel find the...
