Electrochemical technologies have a high potential for display applicationsudbecause of their cheapness and simplicity, easiness to scaling to large substrates and lowtemperatureudnature. However, in major display technologies the oxide films should beuddeposited on transparent conductive substrate, usually ITO on glass. For dielectricudsubstrates like glasses, a special technology of current control is applied to anodizingudmetal films, which changes the oxide porous structure in a final stage and preventsudformation of metal islands. To transform the residual metal nanowires into oxide, audspecial fading process similar to anoding bonding can be done. Usually, high reactivityudelectrolytes are used in the anodizing process, which destroys ITO layers. We haveudanalyzed chemical properties of ITO in various anodizing electrolytes and found someudsuitable reagents and compositions. A lot of functional layers can be created byudanodizing. For example, different filters may be formed by filling the pores by ink jetudprinting. Porous oxides can have low refractive indexes – lower than any bulk material,udand can be used as effective antireflective coatings. A titanium oxide cover film formsud“self-cleaning” surface due to its semiconductor photonics properties and oxygenudproduction.
