Electro-Optical Properties of Index Matched ITO-PET Film for Touch Panel Application

Touch screen displays have been a subject of growing interest in recent years due to the significant usability benefits they provide for portable electronic devices ranging from mobile phones to tablet PCs. In this paper we report the preparation of index-matched ITO-PET films by depositing thin films of SiNx, SiOx and ITO on hard coated polyethylene terephthalate (PET) film utilizing roll-to-roll sputtering system.
