Abstract

An electronic timepiece has 7- segment digital display sections and a dot matrix display section (25). Circuitry is provided to produce a display of characters and/or pictures on the dot display section to illustrate function modes of the electronic timepiece. Slightly altered pictures may be displayed sequentially to give the impression of movement. Thus for example a running figure may be represented. This indicates that the watch is being used as a chronograph. The drive circuit includes a dot matrix pattern generator (22) and a scanning electrode drive circuit (24) for the dot matrix. <IMAGE>
