ABSTRACT:
An electronic watch having a liquid crystal display which presents time information in a substantially conventional presentation of hour, minute and second hands which appear to circulate around the watch face. The display contains sixty equidistant radial hands on an outer circle for the display of both minutes and seconds, and twenty-four equidistant radial hands on an inner circle for the display of hours and half hours. The hands are divided into sets, and each hand in each set is interconnected to form strings of hands with each string having no more than one hand in a set. The circuit interconnections of the hands are provided on a surface of a substrate of the display without crossover of the connecting leads. A parallel substrate has formed thereon transparent electrodes each associated with and overshadowing a set of hands. Thus, in accordance with the invention a matrix arrangement and electronic circuitry are provided for actuating the hands to display time information to the nearest hour, minute and second.
