摘要: 
本文主要研究電濕潤顯示器(Electrowetting Display)油水系統中,施加電壓情況下畫素中不同的側壁擋牆高度(rib height)在不同的油墨厚度收縮與回復情形以及對反應時間(response time)的影響。本實驗使用計算流體動力(CFDRC)軟體進行數值模擬計算電濕潤顯示器,並建立三維網格進行數值模擬電濕潤顯示器驅加電壓後,觀察其開口率、反應時間以及油墨收縮性與回覆性。
本文以214μm×214μm畫素大小進行模擬,在鐵氟龍擋牆高度、油墨厚度、施加電壓等參數下與實做結果比較其趨勢以驗證模擬結果。希望初步提供參數給實驗者或設計者,如油墨厚度、擋牆高度、電壓等對電濕潤顯示器所產生的影響。

In this thesis we mainly study the oil/water system of electrowetting display, to observe oil retraction/spread motion and the effect of response time between different oil thicknesses and side rib heights in the pixel during applying voltage. Computational Fluid Dynamics (CFD) software is used to simulate electrowetting phenomena, which build the structure with three-dimensional grid to simulate when the pixel of electrowetting display is applied at different voltages to obtain pixel on/off switch parameters such as response time, aperture ratio, , and oil velocity in movement.

In simulation, a pixel with area size at 214μm×214μm to simulate different parameters of Teflon rib heights, oil thicknesses, applied voltages to compare the results of both simulation and test sample. The results can provide the design trend of electrowetting parameters such as oil thickness, rib height, voltage for future panel designer.
