Amorphous‐metal thin films can enable a new generation of TFT‐free display backplanes for ultra‐high‐definition (UHD) LCD TVs. This technology builds upon previous efforts to commercialize dual‐select thin‐film‐diode backplanes and addresses issues faced by TFTs in UHD‐TV applications through use of the amorphous‐metal non‐linear resistor. Demonstrating the reliability of amorphous‐metal‐based tunneling electronics and the scalability of these materials to panel‐size processing tools are now the key challenges for this technology.
