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 heightreadable until
5 cmca. 25 m
10 cmca. 50 m
20 cmca. 100 m
40 cmca. 200 m
80 cmca. 400 m
