Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
An electro-optical display for use in an electronic timepiece displaying at least a first function and a second function, said display comprising a plurality of segmented numeric-display elements arranged in a course to display numbers representing information of the first and second functions of the timepiece, at least one compound display element in said course of numeric-display, elements, said compound display element including seven electro-optical display segments having rectangular shapes and positioned in a figure-eight pattern forming two free areas between the segments, said display segments being positioned to display a range of numerals representing information of the first function only of the timepiece upon selective actuation thereof, and an electro-optical signal member having a non-rectangular shape and positioned within one of the two free areas between said electro-optical segments, said member indicating the second function only of the timepiece.
Claim 2
Dependent Claim
140 words
An electro-optical display for use in an electronic timepiece displaying at least a first function and a second function, said display comprising a plurality of segmented numeric-display elements arranged in a course to display numbers representing information of the first and second functions of the timepiece, at least one compound display element in said course of numeric-display, elements, said compound display element including seven electro-optical display segments having rectangular shapes and positioned in a figure-eight pattern forming two free areas between the segments, said display segments being positioned to display a range of numerals representing information of the first function only of the timepiece upon selective actuation thereof, and an electro-optical signal member having a non-rectangular shape and positioned within one of the two free areas between said electro-optical segments, said member indicating the second function only of the timepiece.
