Method and device for repairing open line defect in liquid crystal display array substrate

A method for repairing open line defect in liquid crystal display (LCD) array substrate, which comprises:

• when discovering open line defect on a pattern on LCD array substrate, identifying a repair line path of the open line on the pattern;
• dividing the repair line path into at least two path segments and disposing corresponding coating speed for each path segment;
• and
• for each path segment, performing coating at the corresponding speed to form connected coating on the repair line path.

A device for repairing open line defect in liquid crystal display (LCD) array substrate, which comprises:

• a detection module, configured to detect whether open line defect occurring on a pattern on an LCD array substrate;
• a scanning module, configured to identify and scan a repair line path for the open line on the pattern when the detection module detecting open line defect occurring on the pattern on the LCD array substrate;
• a disposing module, configured to, based on the result of scanning, divide the repair line path into at least two path segments and dispose corresponding coating speed for each path segment;
• and
• a coating device, configured to perform coating at the corresponding speed to form connected coating on the repair line path for each path segment disposed by the disposing module.
