US-based Amorphyx develops amorphous-metals based display backplanes, which can be used to drive displays using quantum-tunneling. The company says that such backplanes will enable extremely fast conductivity and thus "unlimited" refresh rates.

Producing such backplanes is also said to be easy as it uses less layers compared to TFT backplanes, using its Amorphous Metal Non-Linear Resistor (AMNR) technology. AMNR backplanes are suitable for LCDs, OLEDs and e-paper displays. This is still an early-stage technology, but the company demonstrated some prototypes at SID and it will be interested to see if this technology can progress in future years.
