Electronic timepiece circuits

In combination, an electro-optic display having a first layer of display elements disposed in configuration radiating from near the central point of the display and defining radial bars, a second layer of elements disposed in cooperative relationship with said first layer, said second layer of elements being disposed in a plurality of annular concentric groups operatively associated with said radial bars, a first plurality of individually separate electrical paths interconnecting said elements of said first layer into predetermined serially connected groups, each group containing at least two of said radial bars, a second plurality of electrical conductors separately connected to the elements of said second layer and providing means for individually applying electrical potentials thereto, electronic circuitry for driving said display elements comprising a source of electrical signals having predetermined repetition rates, countdown means connected to said source for producing a first plurality of electrical signals varying with time at predetermined rates and representing seconds, minutes and hours, decoding means having a plurality of outputs lesser in number than the number of electrical quantities representing the state of time, said outputs being arranged in predetermined matrix order and connected to combinations of said display elements to provide to said display other electrical signals representing in different combinations analog representations of time, a plurality of conductors interconnecting said countdown means with said decoding means thereby to conduct said first plurality of electrical signals in time shared sequences, and control means connected to said countdown means and effective in response to one predetermined electrical condition for conditioning said other signals to represent one indication of time and in response to another predetermined electrical condition said other signals to represent a different indication of time, said other signals comprising a first subset of signals each having 3 discrete levels and a second subset of signals each having two discrete levels, said first and second subsets being variably applied to said combinations of said display elements to condition said display elements to display analog representations of time.
