What is the ITO
1, The popular explanation:
 IndiumTinOxide, generally referred to as ITO.ITO thin film is a kind of n-type semiconductor material, high conductivity, high transmittance of visible light, high mechanical strength and good chemical stability.It is, therefore, liquid crystal display (LCD), plasma display (PDP), electroluminescent (EL/OLED), touch screen display (TouchPanel), solar cells and other electronic instrument of transparent electrode film of the most commonly used materials.

2, Professiona explanation:
ITO conductive film is to point to adopt the method of magnetron sputtering, sputteringtransparent indium tin oxide (ITO) conductive film coating  on transparent organic film material  and after high temperature annealing treatment for high technology products.The preparation method of ITO thin film evaporation, sputtering, ion plating, chemical vapor deposition, spray pyrolysis, etc., but the most used is the reactive magnetron sputtering method.ITO film thickness is different, the conductivity of membrane and pervious to light performance is also different.Generally speaking, in the same process conditions and performance under the condition of the same PET substrate, ITO film layer is thick, the surface of PET, ITO film resistance is smaller, the less light transmittance corresponding.
