摘要: 液晶顯示器 (Thin-Film Transistor Liquid-Crystal Display,TFT-LCD)在眾多平面顯示器中其技術發展最為成熟且被廣泛應用在日常電子產品。近年來尺寸越做越大,液晶顯示器技術也不斷再創新,品質、成本、良率也成為要求重點。為因應大尺寸面版生產而研發液晶滴入式(One Drop Fill,ODF)製程技術,液晶面版中的液晶層間隙(Cell Gap)內液晶量與間隔柱高度有強正相關。當間隔柱的高低不一致時,影響到液晶層間隙(Cell Gap)空間大小,則伴隨著面版液晶量過多或過少的問題,其風險將影響產品品質不良。本研究將藉由預測量測間隔柱的高度變異,預測ODF製程中液晶層間隙(Cell Gap),達到能自動調整所搭配液晶量的回饋機制自動調整液晶滴入量方法。
TFT-LCD (Thin-Film Transistor Liquid-Crystal Display,TFT-LCD) in a number of flat-panel display technology is the most mature and widely used in everyday electronics. Size bigger in recent years, LCD technology has also been re-innovation, quality, cost, yield requirements focus. Developed in response to the large-size panel production LCD trickle-down (One Drop Fill,ODF) process technology, the Cell Gap LCD panel liquid crystal amount and interval column height was strongly correlated with. Cell Gap affect when the level of inconsistent interval column space size, is accompanied by the panel LCD excessive or too little, will affect the risk of poor product quality. This study by the high degree of variability of the the predictive measurement interval column, predicted the ODF process the Cell Gap, reach can automatically adjust the amount of feedback mechanism with LCD automatically adjusts LCD trickle amount method.
