In the panel production process, some manufacturing or environmental factors may cause defective glass panels. Therefore, a comprehensive testing process is necessary for each panel to complete of the product process. Detection sites require a lot of human visual inspection to find out and repair the defects so that the panel yield can be improved. However, the complex and lengthy processes of professional visual operations result in poor repair performance. This study focused on the improvements of human machine interface, training and operating environment. In addition, statistical tests were conducted to verify the improvement effects on repair performance. The results indicated that: (1) After the improvement of human interface, personnel repair errors have been decreased significantly (mean error repair decreased from 13.52 to 6.56). (2) After the improvement of training materials, academic written exam score have been increased by 5%. (3)Training materials has a significant impact on written exam scores. Either human interface or training material improvement significantly reduced repair errors, but there was no interaction effect. (4) Subjective assessment showed improvement in the operating environment increased personnel comfort and decreased visual fatigue. As the yield enhancement is an important indicator in TFT-LCD, and little research abroad, so we hope that this research can be improved as the direction of the industry.
