Abstract
A liquid crystal digital display electronic wristwatch wherein the digital display is driven at the same potential as the remaining elements comprising the electronic wristwatch is provided. The electronic wristwatch includes an oscillator circuit for producing a high frequency time standard signal and a divider circuit for producing low frequency timekeeping signals in response to the high frequency time standard signal. A decoder circuit produces decoded signals representative of present time in response to the timekeeping signals and a driver circuit in response to the decoded signals being applied thereto drives the liquid crystal digital display. A DC power source is adapted to produce and apply a predetermined potential to at least said oscillator circuit, divider circuit, decoder circuit and driver circuit and thereby operate said respective circuits having said predetermined potential applied thereto at the same potential.
