Other look at the electron device scaling: Trinitron CRT vs iPhone6 Retina HD LED display. Both were extracted for broken units:) Trinitron CRT (Sony's brand name for its line of aperture-grille-based CRTs) were introduced in 1968. Its standard TV resolution was 720x576-pixel for PAL. iPhone6 available since 2014 has the HD LED display 1334x750-pixel. Just estimate volume, resolution and power consumption scaling in both cases.
REF:
- Sony Trinitron A13JZVOOX
5-inch (diagonal) CRT 720x576-pixel resolution for PAL at 192 ppi - iPhone6 Retina HD display
4.7-inch (diagonal) LED 1334x750-pixel resolution at 326 ppi
