ITO conductive film;
The product is widely used in liquid crystal displays (LCDs), solar cells, microelectronics ITO conductive film glass, optoelectronics, and various optical fields.
The main parameters of ITO conductive films include surface resistance, uniformity of surface resistance, transmittance, thermal stability, heating shrinkage rate, and heating curling. Among them, the light transmittance is mainly related to the substrate material used for the ITO film and the surface resistance of the ITO film. Under the same substrate material, the smaller the surface resistance of the ITO film and the thicker the ITO film layer, the more the light transmittance will decrease to a certain extent.
In transparent conductive oxide (TCO), the tin-doped indium oxide (ITO) film has high transmittance and good conductivity, and it is easy to etch fine patterns in acidic solutions, with a transmittance of over 90%. The transmittance and resistivity of ITO are controlled by the ratio of In2O3 to SnO2, typically SnO2:In2O3=1:9.
