Indium oxide, gallium and zinc

Indium, gallium and zinc oxide ( English Indium gallium zinc oxide , abbr. IGZO ) is a semiconductor material that can be used as a channel for transparent thin-film transistors . These materials can be a replacement for amorphous silicon for an active matrix of LCD screens and OLED displays ^[1] . The mobility of electrons of this material is forty times higher than that of amorphous silicon, which makes it possible to reduce the pixel size (for obtaining a resolution much higher than the HDTV format) or the screen response time . New transistors based on IGZO technology do not require constant updating of their state when displaying a still image. This makes it possible to reduce the influence of interference from the electronic components of the screen and reduce energy consumption. Using IGZO leads to increased accuracy and sensitivity of touch panels ^[2] .
