液晶顯示器產業發展至今已超過數十載,已經是我國重要發展產業之一。產品運用上從早期的的筆記型電腦 (Note Book) 、監視器 (Monitor) 領域,後續更將大型領域的電視機應用市場幾乎完全取代。另外近年各種新興用途的消費性產品蓬勃發展,包括娛樂性多媒體產品、手持式與移動性的產品等,例如MP4、觸控手機、GPS、平板電腦等,然而這些新的消費需求下導致產品結構必須增加其他設計,使好不容易於近年大幅降低的產品厚度又暴增。
為解決上述的問題面板業界開始發展將薄化的玻璃基板導入製程中。在現有機台結構下導入薄化玻璃基板會發生彎曲變形過大的問題,目前業界既有的決方法是以公式計算出較佳的支撐間距後,直接停機改造機台結構再確認效果,往往會須要重複多次嘗試方能達到最佳機構條件,造成導入時間長改造成成本高的問題。
本研究希望對於導入薄化玻璃的流程夠建立新的模式,並利用有限元素軟體建立一個簡單但具有趨勢代表性的模型,再於電腦端進行完整條件的軟體模擬,從中確認最佳的條件與玻璃變形趨勢,進而再有效率的改造機台如此可縮短時間與降低成本,此即為本研究最主要的目的。
Liquid Crystal Display (LCD) has been developed for over decades. It has been one of the most critical and developmental technologies in Taiwan. In early periods, LCD is applied to Lap-tops & Monitors fields and then the bigger fields, such as TV market, are almost replaced by this technology. Otherwise, in recent years, oncoming products, including entertaining, multi-media, handheld, and mobile ones, are increasing, such as MP4, touch phones, GPS, tablet PCs…etc. However, the structure of products needs to be added other designs under new comsumer requirements. It leads that the thickness of products which has been reduced for years enormously increases.
For solving the problem described above, the industries begin to use thinned glassed into the manufacturing process. The thinned glasses will sag too much in current machine structures. The current method industries use is to calculate a formula for better supporting intervals in order to directly transform the machine structures and confirm the result. That often needs to be repeated several times for achieving optimal condition and results in longer input time and higher cost.
The goal of this study is to establish a new module, put it into the process of thinned glasses, and create a simple and representative model by using finite element software. The model is simulated by FEM software in computer under faultless conditions. Through the simulation, the best condition and information of deformation trend will be assured in order to efficiently transform machines, shorten time, and decrease cost.
