Name given to
LED displays which use 7
segments, each illuminated by one or more
LEDs, to represent the numbers 0 to 9 (and more rarely, 0 to 9 and A to F).
The
segments are arranged like this:
--
| |
--
| |
--
These
displays might be more
familiar to you as the displays on your
clock radio,
digital wrist
watch, or
microwave oven.
When displaying
hexadecimal, the letters formed look like this: A b C d E F. 7-segment displays can display _most_ other letters relatively
legibly, but have difficulty with letters like W or M. When all the letters need to be displayed legibly, an
alpha-numeric or 'starburst' display is used instead.
