Seven segment displays are quite power hungry relative to what information they can display. LCDs sip power, the issue is their backlight.

- gedy 2y agoI think some folks might be thinking of the older light-emitting 7 segment displays which used more power.
- bobmcnamara 2y agoAh my bad, I was thinking of the early zero power seven segment numeric tape printers. The numitrons used a ton of power. Or was that VFDs?
