A:Answer LEDs: These incorporate brightly lit segments that work in the same way as the little light-emitting diodes (LEDs) used on instrument panels. Typically, LED displays show only numbers (digits), each one made up of illuminated bars (or segments). They work equally well in darkness or light, but consume relatively large amounts of power. VFDs: Combine the advantages of LEDs and LCDs. They're as bright as LEDs but easier to read, and they can be used to display numbers, words, or letters. They're easy to read in darkness or light.
