How digits are wired
Each segment is an LED (or a chain of LEDs in large digits) with one common side: common anode or common cathode. Your controller switches the segments to form each number. Tell us which you need, the digit height and the colour.
Where they are used
Fuel and shop price boards, queue counters, timers and scoreboards, and clocks. For the letters and logos around a price board, see LED modules.
