碩士 === 國立中興大學 === 精密工程學系所 === 98 === 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.
