Abstract

An electronic timepiece has time-keeping circuitry for generating time signals representative of different units of time such as minute, hour, day and date. An elongate dot matrix display displays time information in character form in response to drive signals applied thereto, and electronic circuitry processes the time signals and produces a plurality of sets of drive signals each representative of a different unit of time and applies the sets of drive signals to the dot matrix display to cause the dot matrix display to sequentially display therealong in a repetitive sweeping motion different sets of characters corresponding to the different units of time.
