Representing Letters on a Seven-Segment Display
A common method of indicating an error. |
Representing Letters on a Seven-Segment Display, while highly discouraged, have been done mostly in low-end products such as cheap portable media players and many hobby projects. In such places, 7-segment displays were extended to support letters. Those representations varies from implementation to implementation and are not standardized by any standards organization.
Note that some letters such as K (), M (), V (), W (), X (), and Z () are completely unrecognizable by most people and as such been left out of the table below.
