Abstract :
Electrooptic liquid watch displays driven by the outputs of integrated shift registers provide an unambiguous digital readout for an electronic watch. Also, such schemes simplify the electronics and permit many new watch formats. Eventually, it may be possible to place the electrooptic liquid directly above the IC registers, thus solving the interconnection problem.
