ITO film is an N-type semiconductor material with high conductivity, high visible light transmittance, high mechanical hardness and good chemical stability. It is the liquid crystal display (LCD), plasma display (PDP), electroluminescent display (EL/OLED), touch screen (TouchPanel), solar cells and other electronic instruments transparent electrode most commonly used film material.
Application scope:
①Resistive digital touch screen, analog touch screen.
②Flexible liquid Crystal Display (LCD).
③ Electroluminescent panel (EL Panel).
④ Electromagnetic shielding.
⑤ Frost proof transparent electric film.
⑥ Antistatic.
