摘要: 
聚合物穩定配向技術在廣視角技術中算是一個較新的名詞,其作法為先將聚合物單體參雜於液晶內,之後透過供電使液晶產生一預傾角,讓聚合物單體與聚亞醯胺鏈結,最後再照設紫外光讓聚合物單體反應成聚合物,讓液晶有站立位置。與多域垂直配向技術相互比較,在製程上,彩色濾光片上可減少一道突出物製程,有助於成本降低;在光學上,反應時間加快可以使動態播放時不易有殘影現象,對比度變高可以讓暗態更暗、亮態更亮,開口率變高可以讓背光模組在不增加電壓的狀態下使亮度更亮,達到省能較果。
本研究主要針對一次曝光機與二次曝光機兩種製程參數中,找出最佳參數及最少製程時間兩者相互比較,並搭高、低電壓等條件,探討其光學最佳特性。除電壓之外,一次曝光機之紫外光照射時間、平台溫度以及二次曝光機照射時間等因素也是影響光學特性之重要因素,因此也在本研究的範圍當中。
研究發現高、低電壓對液晶有較顯著擾動現象,唯一較有差別者為對比度,目前推測原因可能與電壓有無經過陣列元件有關。緊接著針對一次曝光機之紫外光照射時間長短作一變化,照射時間愈長,液晶內部的聚合物單體反應成聚合物會愈多,聚合物愈多,液晶站立的位置也會愈多。在針對一次曝光機平台溫度高低作變化則會影響到聚合物單體與聚亞醯胺的反應速率,溫度愈高,反應速率愈快,但會有不同方向之預傾角;溫度愈低,反應速率愈慢,會有液晶旋轉位移瑕疵產生。變化二次曝光機照射時間長短會影響到液晶內部的聚合物單體殘存量,殘存量太高則會有影像殘留現象產生。
最後從以上實驗數據中,挑選出最佳條件,並利用一次曝光液晶檢查機與人員觀看兩種檢測模式相互確認,以確保產品品質。
