Indium gallium zinc oxide (IGZO) is a compound semiconductor material including the chemical elements indium, gallium, zinc, and oxygen (O). The TFT backplane of flat-panel displays (FPDs)contains IGZO thin-film transistors (TFT). The electron mobility of IGZO-TFT is 20–50 times that of amorphous silicon, which is commonly used in liquid-crystal displays (LCDs) and e-papers. Thus, IGZO-TFT can enhance flat-panel display speed, resolution, and dimensions. It is currently used as the thin-film transistor in organic light-emitting diode (OLED) television displays.

IGZO exhibits superior carrier mobility compared to zinc oxide while also possessing the distinct benefit of being capable of homogenous amorphous phase deposition. The potential of a completely transparent transistor is made possible because although the transistors are slightly photosensitive, the effect only really becomes noticeable in the deep violet to ultra-violet (photon energy above 3 eV) region.
