Index Matching of ITO-PET Film and ITO Glass by Organic Coating and Performance

摘要

The visibility of patterned ITO layer on ITO-PET film or ITO glass is a cumbersome process in fabrication of projective capacitive touch screen panel (TSP). In order to solve this problem deposition of index matching thin films is used utilizing sputtering system. In this work we developed organic coating as an index matching process which could be carried out under ambient condition with easy adoption to roll-to-roll process. The design, simulation and measurement of the index matching process and performances are discussed.
