Summary: | 碩士 === 中原大學 === 工業與系統工程研究所 === 99 === Marco inspection station is one of the main inspection tasks in the TFT-LCD manufacturing process. This illumination system of macro inspection of TFT-LCD is used on bigger size of glass in the manufacturings factor. The macro inspection adopts it’s transmission and reflection of light on the glass to observe the mura or some foreign matters easily. By means of color temperature, we can inspect the different defects of the different glass, we usually use neon light, sodium light, highlight and green light as the original light sources. Because of long searching time on the glass panel, marco inspection operators frequently complain about visual fatigue problems. In this study, we evaluated the visual fatige of the marco inspection operators using critical flicker frequency (CFF) and subjective eye fatigue rating. A total of 50 marco inspection operators participated in this study and conducted the experiment in the clean room. The results indicate that the marco inspection operators checked the panel for a long time in array department, with significant eye fatigue. It is recommended to improve the work station and improve the marco inspection operators’ visual fatigue problems.
