Japanese Patent JPS51104568
Kind Code:
A
Abstract:
An electronic timepiece wherein the operative elements defining the digital display timepiece circuitry are formed on an organic film substrate is provided. The digital display electronic timepiece circuit includes a battery and timekeeping circuitry coupled to the battery in order to be energized thereby and produce low frequency timekeeping signals representative of actual time. The timekeeping circuitry is integrated into at least one circuit chip. A digital display panel receives the timekeeping signals and digitally displays time in response thereto. The organic film substrate supports the display panel each timekeeping circuitry circuit chip and circuit wiring operatively connecting the display panel and chip and formed on said substrate on the same side thereof. Other electrical components of said timepiece may be supported on the opposite side of the substrate.
