    Abstract: 液晶顯示器的應用已非常普及,而液晶顯示器的製造廠商有一個
    器的VCOM 電壓,藉此來達到自動化調整的目的。
    得到最佳的檢測結果。另外透過量測數據與Waveform 分析,找尋出
    最佳的調整電路與分析方式,以提升量測效率及符合產品需求。;The LCD application is very popular now, and that comes with
    a very serious topic is how to detect and fine tune flicker
    status at essential production line stage. That becomes a very
    import task of LCD manufacture.
    In this study, we propose an automated detection system
    which use photodetector to measure level of flicker, and use
    sampling circuit to convert into digital signal. And then by
    analyzing that signal, we use digital control signal to adjust
    VCOM to achieve automatic fine-tuning.
    We focus on the way of measuring and analyzing in this study.
    Propose to use diversion of different circuit to analyze data
    to get the best test result. And also we can measure data and
    use waveform to analyze to get the best way and fine-tuned
    circuit to improve efficiency and fulfill product request.
