Abstract:	背光模組為液晶顯示器面板的關鍵組件之一。功能在於供應充足的與分布均勻的光源，使其能正常顯示影像。我國廠商已具有導光板光學與機構的設計能力，加上組裝製程較日本、韓國具有成本優勢，但由於背光模組產業進入障礙不高，且技術門檻低，因此廠商仍須在生產技術、製程改善及量產規模經濟上努力並發揮綜效，達到成本的降低，以確保市佔率。生產流程是製造型企業至關重要的一個組成部分，於背光模組甚是。因此，當一個製造型企業需要進行發展改進時，對企業的生產現狀做價值流圖分析，發現企業的增值部分，從而優化生產流程就是一種必要的手段和有效的措施。為了使企業在市場中保持良好的競爭力，對於生產流程的優化是需要持續不斷進行的。本研究採個案研究方法，藉由文獻探討相關理論，針對個案公司藉由導入精實生產（Lean Production）的方法來改善背光模組製程及生產力提升的實施成效，其目的期使能優化製程上之工站、組裝動作、人員配置，增加產量、降低成本及創造利潤，以增加業界之生產力及競爭力。經實證研究結果顯示，應用精實生產手法使產能由4500片/線/10H提升至8000片/線/10H，產能提升78％；空間產出提升77.8％；單片人工成本費用降低12％。總結實施成效，確認可進行推廣延伸，由單一機種導入至全機種，或由單一線體複製至全部線體及集團其他之廠區。 ;The backlight module is one of the key components for the liquid crystal display. Its function is to supply sufficient and uniform distribution of light, so that it can display the image properly. The companies in Taiwan have had the ability to design the optical light guide plate and mechanical structures. Moreover, the assembly process has a cost advantage than that of Japan and South Korea. Because of the low barriers to entry backlight module industry and low technology, manufacturers still need to improve the production technology, the assembly process and the mass production economies of scale and strive to play a synergy, to reduce costs in order to ensure market share. Manufacturing production processes is a vital part of the enterprise, especially in backlight module industry. When a manufacturing company needs to develop improvements to the current situation, the company has to plan a value stream analysis, which we found necessary means and effective measures is the key value of optimizing production processes. Therefore, in order to maintain a competitive edge in the market, the optimization of production processes is the need for continuous ongoing process. In this study, we present a case study including reviews on related literatures. The company introduced lean production method to improve the backlight module manufacturing processes and the effectiveness of the implementation of productivity improvements, with the aim of enabling the optimization process of the work stations, assembly operations, staffing allocations, increasing capacities, downsizing costs and creating profits to increase the productivity and competitiveness of the industry. The empirical results show that application of lean production techniques can be increased from 4500PCS / line / 10 hours to 8000PCS / line / 10hours. The production capacities is increased by 78%; the output space is increased by 77.8%, and monolithic labor costs were decreased by 12%. As a result, it is capable of extending the lean production techniques from a single production line to the others, and tp the production units in the companies as well.
