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.

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

Seven-Segment LCDs

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