"Actually the Cathode Ray Tube is Victorian, dating from 1897."
True.
But the core requirement is no flowing electricity. IE no DC, no AC.
Static charge (generated within the mechanism) is just about OK.
But preferred primer movers and drivers are mechanical, pneumatic, hydraulic with light generated by gas, oil or lime light (that's gas flame exciting a lump of lime)
