彩色濾光片修補方法之比較及其改善策略之研究

Abstract

薄膜電晶體液晶顯示器(TFT-LCD) 產業為台灣繼半導體產業後，另一個明星產業。本研究以彩色濾光片為對象，探討如何修補彩色濾光片缺陷。當面板尺寸愈做愈大，反應速度愈來愈快，原來的的修補方式已無法有效降低報廢率，各彩色濾光片廠及設備商無不絞盡腦汁，開發出新的彩色濾光片修補方式，本文針對彩色濾光片的新修補方式，根據實驗結果及特性提出改善策略。然而，為了降低彩色濾光片的生產成本，一些TFT-LCD廠發展出新的彩色濾光片製作方法 ”噴墨列印技術(IJP)”，已列為各彩色濾光片廠的最高發展原則，針對此新製程所產生的缺陷如何作修補也一併作討論分析。

TFT LCD industry, obviously, is another star industry step after semiconductor in Taiwan. This thesis is subjected to the color filter and discusses how to repair color filter defect. When the panel size is made to be bigger and bigger, the response time is also getting faster and faster. The original type of repair method can’t decrease the defect ratio effectively . Thus all color filter makers and equipments suppliers are trying to develop new repair method. This thesis is discussed to the new repair methods for color filter and base on experimentation result and characteristics provide the improvement method. However, for reduce production cost of the color filter; some TFT LCD makers develop new producing method of the color repair called “IJP (Ink Jet Printing)” which has been listed as a top principal of development for every color filter makers. Regarding to the defect repair method caused by this new producing method will be also discussed and analyzed here.
