Definitions

  • the invention relates to an electronic clock with a display device containing twelve optoelectronic display units, each display unit includes lighting means for forming a visually distinguishable from the other display units light source, and the bulbs are arranged at intervals about a central point at locations corresponding to twelve hour marks, for displaying the hours and minutes, and further comprising a microprocessor with an electronic control device for controlling the individual display units. Furthermore, the invention relates to a method for time display in an electronic clock.

This reduces the total number of display elements to twelve.
