The transparent conducting oxide (TCO) film is a significant component in flat panel display industry, applied for flexible display, e-paper, and touch panel. The TCO materials have high refractive index, so the phenomenon of high reflectance is the major issue and needs solved in present and future market. In this study, the structure and process of new lower reflection TCO hybrid film is introduced. The laser interference lithography and UV nanoimprint are combined for fabrication of sub-wavelength structures on PET film, then the tin-doped indium oxide (ITO) deposited on structures. Finally, the best result of this hybrid film is reflectance reduced to 3.3% at wavelength 550nm, just 13% of the original film, and the resistance of ITO layer is 1.05x10-3 Ω-cm. This result is useful for the TCO film applied in low reflection demand products in the future.
