LED displays
How should it be made up?
The following specifications give the best results:
- Create media exactly at display resolution.
- Enlarge text and image for best readability.
- Note the positioning at full pixels for rectilinear shapes.
- Use light colours on a dark background to reduce light emission and achieve optimal contrast.
Text size
We often use the following rule of thumb to determine the minimum size of the text:
height in cm × 5 = reading distance in m
See the table for some examples.
| Character height | readable until |
|---|---|
| 5 cm | ca. 25 m |
| 10 cm | ca. 50 m |
| 20 cm | ca. 100 m |
| 40 cm | ca. 200 m |
| 80 cm | ca. 400 m |
