Abstract
Improved timekeeping apparatus, such as a watch or clock with an electro-optic display simulating a conventional mechanical analog timepiece. Electro-optical material, e.g., liquid crystal material, is activated in selected areas to change its appearance to simulate movement of the hands.
Claims8
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, and a second plurality of electrical conductors separately connected to the elements of said second layer and providing means for individually applying electrical potentials thereto, said first plurality of individually separate electrical paths including a common electrical hub at the central point of said display to effect electrical connections between a predetermined plurality of said radial bars.
