Seven segment is a pixel layout. LCD/LED are pixel types. Seven segment LCDs are super low power, and can be made to reflect through ambient lighting.

- 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?
