Abstract

An electronic timepiece having liquid crystal or light-emitting diode display elements provides a logic network for flickering a part or all segments of the display element at a plurality of repetition rates and duty cycles, whereby additional intelligence associated with the repetition rate and duty cycle is conveyed by the display element. The logic network gives priority of display to any one preselected supplemental flickering intelligence function when there is a coincident demand for more than one supplemental function for display. Flickering draws attention to the supplemental intelligence contained in an otherwise continuous display.
