Abstract

The invention provides a detection and repair method and system for TFT-LCD color film glass substrates. The method includes the steps that zero defect information of the products and repair instructions and repair procedures corresponding to all defects are input into a repair device; the color film glass substrates are detected, and color film glass substrates detected to have defects are compared with the zero defect information, in the repair device, of the products to obtain position and area information of the defects; repair operation is performed according to the position and area information of the defects in combination with the repair instructions and the repair procedures. According to the detection and repair method and system for the TFT-LCD color film glass substrates, the TFT-LCD color film glass substrates can be automatically detected and repaired through the repair device; compared with a traditional manual detection judgment and grinding repair method, the labor cost is greatly lowered, the quality and production efficiency of the products can be improved, and the quality stability of the products can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of TFT-LCD colored film glass substrate processing technology, in particular to a method for detecting and repairing a TFT-LCD colored film glass substrate and a system thereof. Background technique [0002] At present, in the TFT-LCD color film factory, substrates with black defects (PR glue residue) will be arranged after PS (PostSpacer, the spacer behind the TFT-LCD panel supporting the liquid crystal box, the last Photo process of the color film) Or there are foreign objects) to the RepairLine for repair, while the inspection and repair process after the PS process requires manual operation of the repair equipment to grind and repair black defects, and manually determine OK & NG for various microscopic defects according to the established bad judgment standards. [0003] In the prior art, the detection and repair process of the color filter glass substrate is as follows: [0004] 1. First, AOI (the full...
