A digital clock is a type of clock that displays the time digitally, i.e. in cyphers, as opposed to an analog clock, where the time is displayed by hands. Usually, digital clocks are associated with electronic drives, but the "digital" description refers only to the display, not to the drive mechanism. (Analog clocks are driven mechanically or electronically.) The biggest digital clock is the Lichtzeitpegel ("Light Time Level") on the television tower Rheinturm Düsseldorf, Germany.
