seven-segment display

A common display found on digital watches and readouts that looks like a series of 8s. Each digit is formed by selective illumination of up to seven separately addressable bars. For more details, see LCD types.


Seven-segment Display
Using two seven-segment digits, this readout can display from 00 to 99. Each of the seven segments has its own contact to the outside electronics. (Image courtesy of LXD, Inc.)







Introduced in 1973, this was one of the first LCD watches on the market. Notice how the seven segments make up 0 through 9. LED watches, with their bright red digits, came out a couple years earlier. (Image courtesy of the private collection of Peter Wenzig.)
