本論文主旨係探討有機發光顯示器(Organic Light Emitting Display)在真空環境下使用熱蒸鍍製程將有機發光材料蒸鍍於玻璃基板,相關熱蒸鍍製程參數對於玻璃基板的熱膨脹量影響關係,包含熱蒸發源的溫度、蒸發源與玻璃基板間的距離、鍍膜的速度、鍍膜次數、玻璃基板冷卻等,對於玻璃基板表面溫度與金屬mask熱膨脹不匹配性之影響,利用溫度計算膨脹量估算兩者膨脹量差異,建立參數與膨脹量關係式進行模擬與驗證。
蒸發源與玻璃基板間距離調整30mm可使玻璃基板產生溫度差達3.4℃,玻璃與金屬mask膨脹量差6.9μm;鍍膜次數與速度影響玻璃基板接受熱輻射的時間,鍍膜時間差30sec,可使玻璃基板產生溫度差達0.8℃,玻璃與金屬mask膨脹量差1.6μm;以上兩項為主要影響玻璃基板表面溫度升高的重要因子,因此可使用這些參數關係控制膨脹量。
In the thesis we study the parameters affecting the thermal expansion of the metal mask and the glass of panel of Organic Light Emitting Display during the evaporation process, and establish the relationship between these parameters and the thermal expansion of glass substrate.
The parameters include heat source temperature, distance from the heat source to glass substrate, heat source scan speed, heat source scan times, chiller cooling temperature in vacuum chamber. Firstly we use different parameters to evaluate the effect of the surface temperature on the metal mask and the glass substrate to calculate the difference of thermal expansion between the metal mask and the glass substrate, to establish a table for further estimation purpose.
The main factors are the evaporator time, heat source temperature and the distance of heat source to glass substrate. Their relationships of the can be used to control the thermal expansion of the glass substrate.
