What are LED digital tubes, and how do they work?

LED digital tubes are specialized display devices that use light-emitting diodes (LEDs) arranged in a segmented structure (typically 7 segments per digit, plus a decimal point) to display numeric values (0-9) and basic symbols.  Each segment is an individual LED that lights up when an electric current passes through it.  By activating specific combinations of segments, the tube produces clear, legible digits—making them ideal for applications where numeric data needs to be displayed simply and reliably.  They operate on low DC voltage and use solid-state technology (no moving parts), ensuring stable performance.
