- Visibility angle is much better than any other alternative. This is crucial when one big display is used in a very large room instead of many small displays.
- Image sharpness and contrast is excellent. You can read text on an old flip display far away that you would struggle to read on a modern LCD if you have mild astigmatism.
- Perfectly readable on a sunny day.
- They can show colored logos and symbols (e.g. train type, airline, highlight warnings)
- Better failure mode than LCD: single digits fail independently from each other and can be replaced. But it's less likely that the entire display fails.
- They are either working or stuck - no fading out like CRTs.
