The viewing angle is the
angle at which the LED brightness is at 50% of its maximum.
Our internal displays typically have a viewing angle of 160°.
Our external displays typically
have a viewing angle of 38°.
Where a greater viewing angle is required, we can use elliptical
LEDs, which give a minimum viewing angle of 60°
depending on colour.

As a general guide, for
every 25mm character height the viewing distance increases by 15 metres.
There are however many factors that effect the viewing distance. Some of
the factors effecting the distances are :-
