Digital display electronic timepiece

Claim 1

A digital display electronic timepiece circuit assembly comprising in combination battery means, timekeeping circuitry coupled to said battery means for being energized thereby and for producing low frequency timekeeping signals representative of actual time, said timekeeping circuitry being formed in at least one intergrated circuit chip, a digital display panel for receiving said timekeeping signals and digitally displaying time in response thereto, and an organic film substrate, said film substrate, including an electric wiring pattern formed on a first surface thereof, said substrate supporting said display panel and each said integrated circuit chip on said first surface to thereby electrically couple said display panel and each said chip together by said wire pattern, the surface of said film substrate not supporting said display panel being adapted to secure said battery means, said substrate having a first through-hole for receiving a portion of said display panel, said digital display panel including a front glass panel of substantially larger widthwise and lengthwise dimension then said portion of the display panel received in the through-hole of said substrate, the back surface of said front panel having segment electrode leads disposed thereon and coupled to said electrode wiring pattern formed on said first surface of said film substrate, said back surface of said glass panel being dimensioned to structurally support said organic film substrate and certain of said elements supported on the back surface thereof, said front glass panel further including an opening therein for permitting said integrated circuit chip to be supported on said organic film to extend through said opening.
