摘要


電容式觸控面板用來偵測觸控動作及位置的圖樣化ITO層,除了會造成反射率高、穿透率低、色彩偏移…等問題,且當圖樣化ITO的圖樣區與空白區之色差大於人眼恰可察覺色差時,則人眼可感受到色差存在,ITO圖樣就會出現在顯示畫面上,干擾顯示畫面,不利於顯示器要求的光學品質。本篇論文利用薄膜光學、色彩學、數值分析等相關理論建立一套模擬環境,提供了光譜、色彩及ITO圖樣色差等計算。可進一步加入其他材料膜層,並針對設定的目標進行各膜層厚度的最佳化,如樣品反射率最低、穿透率最高、ITO圖樣色差最低…等,降低了薄膜光學設計的困難度。更進一步將其用來針對電容式觸控面板進行光學設計,以得到最佳的光學性能,並消除ITO圖樣干擾顯示的問題,提高顯示器的光學品質。

The patterned ITO layer used to detect touch action and location on the capacitive touch panel, not only will result in high reflection, low transmission, color shift and other issues, but also will cause human eyes can observe the ITO pattern appears in the display screen, interference with the display images, is not conducive to the displayer requirements of the optical quality. We use thin-film optics, color science, numerical analysis and other related theories to establish a simulation environment to calculate the spectrum, color, and ITO pattern color difference. It can add other material layers, and optimize the films thickness, reduces the thin-film optical design difficulty of the target such as maximizing transmittance, minimizing reflectance, ITO pattern color difference and so. Further, the optical design used for the capacitive touch panel to get the best optical performance and eliminate the problems due to the ITO pattern interference with the display images to improve the optical quality of display.
