The touch screen on your laptop/phone are definitely made with "transparent' conductors. These range from ITO and Silver Nanotubes on LCDs to patterned aluminum mesh (Samsung's OCTA is On Cell Touch AMOLED) and semi-transparent cathode (~10nm Ag/Mg ground current return layer) on OLEDs.
Those electrodes are literally used as capacitive antennas to detect the position of your fingers and they range from about 300ohm/sq to 1ohm/sq. Depending on the capacitive coupling they range from GHz to 100kHz bandwidths.
I was trying to understand if "transparent" was literally a property of the metal, of if it just means "so thin that you can't see it".
