薄膜電晶體液晶顯示器（Thin Film Transistor－Liquid Crystal Display，TFT-LCD )製造業為台灣近年來蓬勃發展之高科技產業，TFT-LCD我國總產值居世界第二位，僅次於南韓，被視為繼晶圓代工後，台灣電子業下一波主流產業。由於本產業於國內仍屬新興工業，許多與製程相關之作業評估及危害資料尚未建立，加以TFT-LCD面板產品尺寸不斷的放大，相對的產品重量也隨之增加，除了人員作業範圍半徑較大外，搬運標的物的重量也造成負荷。 本產業雇用了大量勞工從事製程之操作及品管作業，尤其是模組廠後段製程之產品組裝及搬運，由於作業人員長時間執行重複性、耗體力之作業，因此這種特殊作業環境是否會對人員造成肌肉與骨骼方面的損傷，值得進一步探討。本研究目的即為探討TFT-LCD模組製程作業人員肌肉骨骼不適之情形，藉由現場工作觀察，辨識危害因子，並研提改善計畫與建議，冀能藉本研究成果作為業界改善之方針及參考。 研究對象為北部某TFT-LCD模組製程之員工，本研究可分為三部分，第一部分是進行員工診所就診資料調查搜集，了解作業人員健康狀況或肌肉骨骼的不適部位，第二部分利用設計改良式問卷檢核表，進行各站點危害評估，第三部分為現場環境觀查量測。研究結果發現，模組製程作業人員肌肉骨骼不適症狀比率頗高，因此建議改善建議設置可上下調整昇降之工作平台、可自動鎖螺絲裝置、增設站坐二用椅、增加休息時間、實施輪調制度、實施健康管理或辦理職場健康促進活動，預防工作累積性之肌肉骨骼傷害，減少人因工程風險。 Thin Film Transistor-Liquid Crystal Display (TFT-LCD) manufacturing has experienced vigorous development in recent years in Taiwan. It becomes the second wave of the island country’s high-tech industry development. Taiwan's production rate of flat panels is currently ranked second globally, next only to South Korea. Since manufacturing processes and the size of displays continue evolving, process hazards and, particularly ergonomic hazards, are unknown to most companies. Increased size of TFT-LCD panels and the relative weight of the new products demand more personal movement and work load. This thesis is aimed to evaluate employee muscularskeletal disorders of a TFT-LCD module manufacturing process. This study is divided into three phases. The first phase was to collect clinical information to understand the health status and musculoskeletal discomforts of the employees seeking temporary relief. The second phase used questionnaires to conduct ergonomic risk assessment of various work stations. And lastly, on-site observations were conducted to analyze ergonomic hazards of the tasks involved at each work station. The results illustrate that musculoskeletal disorder symptoms of the module manufacturing process are relatively high and vary among different work stations. It is proposed that employee upward and downward movement adjustments of the work platforms, automatic screw-locking device, installation of sit-stand dual function chairs for temporary rest, job rotation, workplace health management and health promotion can be considered to alleviate employee cumulative musculoskeletal disorders and to achieve better control of ergonomic hazards.
