What is LED?
| Light-Emitting Diode |
|
The big advantage of LED displays over liquid crystal types is that you don't need decent ambient light to see them, because they 'glow'. On the downside LED's need much more power (since they're constantly pumping out energy as light) and are difficult to build into compact, high-resolution displays. However, they are widely used for indicators, instrument readouts and signs where only a few elements are required. |
