Abstract

The invention provides an array substrate repairing method. The method comprises the steps that to-be-repaired array substrates are divided into two groups; a laser repairing unit is used for identifying positions of defects of the first group of array substrates and repairing point defects, and meanwhile, a laser long-line unit is used for repairing the second group of array substrates; the arraysubstrates, which are repaired by the laser repairing unit and have line defects, in the first group of array substrates are conveyed to the laser long-line unit for repairing; under the condition that 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 conveyed to a centralized processing machine table to be concentrated; all the array substrates located on the centralized processing machine table are transported to a sorting machine table, and the repaired array substrates and the to-be-repaired array substrates are classified and sequenced on the sorting machine table.

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...
