技術簡介
本技術探討平面顯示器製程中所發生的熱翹曲問題,並基於多層梁熱變形理論基礎提供實驗建議以反推彈性模數與熱膨脹係數等材料參數。同時探討多次塗層、塑性變形、預拉伸應變等幾種對於玻璃基板影響熱翹曲的因素,以及調整鍍膜或塗層的厚度匹配,以降低熱翹曲量的可能性
Abstract
The finite element method is employed to study thermal warping and its causes in the flat panel display industry. First of all, an experimental method based on the Stoney equation is proposed to obtain the material constants such as elastic modulus and thermal expansion coefficients. In addition, several factors which affect thermal warping are analyzed. They are multi-layered coating, plastic deformation, pre-tension. Finally, the possibility of zero warping is shown by tuning the combination of thickness of the films on the glass substrate.
