LED displays

LED displays are always employed, if units are to be used in environments with diffuse lighting. Due to their self-luminous display, these models are also easy to read even from a long distance.

For each segment, LED displays require a current of between 2 and 10 mA. For a 6 digit counter that could mean from 90 to 450 mA.
A further disadvantage is that no additional symbols can be displayed. As a rule 7 segment displays are the norm, although 14 segment displays or alphanumeric displays can be used to display message texts.
