If the ITO glass surface exerting the voltage spreads the exceeding and dredging the insulating membrane of super hydrophobic, can improve operating by reliability effectively, prevent from too phenomenon electrode not caused not electrolytic destroy with solving liquid from. This phenomenon calls ' the (Electrowetting-On-Dielectric, EWOD). Studying will have oil blue that will be dripped in the container of a little shape afterwards, the top has paved one more layer of water, once exert the voltage between ITO electrode and water, it is exposed to tension and will change the oil blue will be crowded on one side, this movement is that Electroweeting Display the principle. So the Electroweeting Display the principle already for the liquid, Wetting phenomenon produced because of static electric field function , this can control Wetting performance by changing surface chemical or surface micro-structure while water insulating . This text will be by way of changing surface micro-structure (roughness surface), research and discussion. Expect via roughness surface to take characteristic analysis and discussion believe that there is suitable aid in the (electroweeting display) design respect.
