Abstract
Abstract A display method for a solid state electronic timepiece wherein separate indicia to be displayed are disposed on a display surface of said watch and means are provided for selectively visually identifying one or more of said indicia. Said indicia are preferably representative of the days of the week. Each of said indicia may have a liquid crystal or luminous diode display associated therewith which may be selectively energized to identify the desired indicia, or may be covered by a liquid crystal screen which, when selectively energized, obscures all but the desired indicia.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
174 words
In a solid state electronic timepiece having a time keeping mechanism and a time display mechanism responsive to said time keeping mechanism, the improvement which comprises a plurality of separate indicia other than numerical characters on said timepiece and means in the region of each indicia but not including said indicia for selectively visually identifying a selected one or more of said indicia in response to said time keeping mechanism of said timepiece, said visual identifying means including liquid crystal screen means positioned over each of said indicia, each of said liquid crystal screen means being adapted for alternative disposition in either a substantially opaque state or a substantially transparent state depending on the nature of the signal applied thereto, said time keeping mechanism including circuit means for producing an output signal for application to said liquid crystal screen means for selectively disposing the liquid crystal screen means associated with one or more of said indicia in the transparent state and rendering the other of said liquid crystal screen means in the opaque state.
Claim 2
Dependent Claim
174 words
In a solid state electronic timepiece having a time keeping mechanism and a time display mechanism responsive to said time keeping mechanism, the improvement which comprises a plurality of separate indicia other than numerical characters on said timepiece and means in the region of each indicia but not including said indicia for selectively visually identifying a selected one or more of said indicia in response to said time keeping mechanism of said timepiece, said visual identifying means including liquid crystal screen means positioned over each of said indicia, each of said liquid crystal screen means being adapted for alternative disposition in either a substantially opaque state or a substantially transparent state depending on the nature of the signal applied thereto, said time keeping mechanism including circuit means for producing an output signal for application to said liquid crystal screen means for selectively disposing the liquid crystal screen means associated with one or more of said indicia in the transparent state and rendering the other of said liquid crystal screen means in the opaque state.
Claim 3
Dependent Claim
62 words
A solid state electronic timepiece as recited in claim 1, wherein said liquid crystal screen means are adapted to be rendered opaque upon the application of a signal thereto, said circuit means being adapted to apply a signal to all of said liquid crystal screen means except the liquid crystal screen means associated with the one or more indicia to be identifieD.
Claim 4
Dependent Claim
96 words
A solid state electronic timepiece as recited in claim 5, wherein each of said indicia is representative of a day of the week, said time keeping mechanism including a time standard oscillator means, frequency dividing circuit means coupled to said time standard oscillator means for dividing the output signal of said time standard oscillator means, said divider means being adapted to produce an output signal representative of each of the days of the week, said visual identifying means being responsive to said divider means output signal for providing a visual indication of day of the week.
