Abstract:
本發明係一種具有主動控制之可調式場發射型顯示器(active matrix current source controlled gray level tunable FED),其利用主動元件將電壓控制訊號轉換為電流輸出,並利用電容記錄及維持上述電壓控制信號,以產生低控制電壓主動電流源驅動場發射型顯示器(low control voltage and active current source driving FED),可達到調整與維持其灰階及亮度(brightness)的目的。經由使用上述主動元件及電容,使亮度維持固定,如此,場發射型顯示器(FED)操作於較低電壓及亮度下,即可得到高瞬間亮度(high transient brightness)以產生高平均亮度(high average brightness),同時,也可避開高壓時產生的電弧電流(arc current)問題。另外,由於可由電流源控制流過場發射型顯示器的電流,故因真空不良而產生的大電弧電流,會被固定電流源壓制,使電流保持在定值,防止電弧(arc)產生,提升場發射型顯示器的良率。
