The rumour of a liquidmetal display might refer to these 2 patents, where the home button disappears and is replaced by a metal assembly under the OLED screen,

I cant decipher what the technicals mean in the patent regarding electrostatic, dielectric, insulated, conductive, capacitive, but i do know that, at the very least, a grainless BMG alloy would be best suited to read the fine fingerprint details than crystallised metal would.

A side note, BMG is already used in the home button of all iDevices (except the new iPhone7)
Apple just never mentions it.
