ITO conductive film, which can conduct electricity and transmit light, is a kind of "transparent conductive film". After the ITO conductive film is coated on the glass substrate, if the glass is used for the window, the ITO film can reduce the fog of the window after being electrified; if the glass is used as the accessories of the liquid crystal display, the ITO film is etched into a circuit, and the deflection degree of the liquid crystal can be controlled after power on, so we can see the light coming from the back of the liquid crystal, and these lights constitute the image; because the liquid crystal molecules must be clamped in two electricity Therefore, both sides of the LCD panel (TF and CF) should be coated with ITO.
