臺灣博碩士論文加值系統

由於光電產業之平面顯示器對於TFT-LCD(Thin Film Transistor Liquid Crystal Display)面板的需求逐漸增加，自2001年起成為明星產業並興起了投資熱潮。近年來台灣製造液晶螢幕的產業外在競爭加劇，面臨技術提升的南韓以及逐漸崛起的中國相互競爭，改善製程技術以提升生產效率及產出良率，從基礎科學研究中開發出關鍵技術，讓台灣保持永久的競爭力。
本文以數值模擬方法探討玻璃於二維熱風多層爐中的受熱均溫性，均溫性會影響到玻璃面板產出的良率，由初步模擬結果觀察到流速會影響玻璃溫升的速率，嘗試將多孔板置於玻璃面板前的區域，透過不同孔隙率之多孔板調整各層入口速度，比較結果顯示加入多孔板後，各層的速度之標準差由2.34m/s降低至0.31m/s表示各層速度差值降低，且玻璃加熱所需時間由600多秒縮短至300秒。

In this paper, the numerical simulation method is used to investigate the temperature uniformity of glass in a two-dimensional TFT-LCD oven model. The temperature uniformity affects the processing quality of the glass panel. However, the velocity of air between two glass panel is the crucial factor. Placing the perforated plate with different porosity in front of the glass panel to adjust the inlet velocity of each layer. The simulation results show that the standard deviation of the speed is reduced from 2.34m/s to 0.31m/s after the addition of the perforated plate. In addition, heating time is shortened from 600 seconds to 300 seconds.
