Paper Abstract

This paper describes an automated method for classifying defects on the electrode-lines deposited on a flat panel display. These defects are presented to the operator at the semi- automated panel repair station during operator repair. The defect categories include surplus gold between electrodes, excessive gold on the line, not enough gold on the line, broken line, wide line width, gold strain stick, gas bubble, and semitransparent materials. The automated method will eliminate the deficiencies of human visual classification by providing fast accurate and repeatable defect classification. The process will free the operator from much of the work associated with data logging during the repair to enhance operator productivity. The system will classify defects by analyzing selected features in each observed defect with a set of previously defined rules and it also processes video data in real-time during the repair operation. Results can be used to control the manufacturing process to reduce the occurrence of defects or for selection of the proper repair procedure.
