中文摘要 本文主要是發展了一套方法去縮短設計電容式觸控面板的時間,讓整個設計流程更有效率。電容式觸控面板的電場線性度對於觸控面板的品質有很大的影響,而電容式觸控面板上的電極佈局會直接影響電場的均勻度。本文係在VBA (Visual Basic for Application)程式語言的環境下發展出一套參數式的設計工具。利用此工具可將電容式觸控面板上電極參數化,使用者只須去定義數個參數就可以快速的畫出複雜的電極圖案。此工具不但可以縮短設計電極圖案的時間,當電場線性度不佳時,也可以利用此工具去快速地修改電極圖案。在本文中也對電極元素的幾何形狀做測試,可以讓使用者有一個初步的概念知道如何調整電極可以得到較佳的電場線性度。最後,利用此參數式設計工具實際畫出一個10.2吋的電極圖案並實作出10.2吋的電容式觸控面板作驗證。


英文摘要 This thesis aims at developing an efficient method for designing the electrode pattern in capacitive touch panel. The linearity of the electrical field on the capacitive touch panel is very important to the quality of the touch panel, and the distribution of silver electrodes on the panel is the key to improve the electric field. A parametric design tool is established under the Visual Basic for Application (VBA) program language. The dimensions of the silver electrode are parameterized in this parametric design tool. The electrode pattern can be established by defining these parameters. This tool not only can shorten the time of designing the electrode pattern, but also can adjust the geometry of silver electrodes easily. A 12.2 inch electrode pattern is designed by using this parametric design tool to prove the feasibility of this tool. Seven kinds of element geometry test can be used to adjust the layout of the silver electrodes for good linearity. Finally, a 10.2 inch electrode pattern is fabricated and validated.
