Abstract
A combined analogue and digital display device having a plurality of individually energizable display elements arranged symmetrically with at least some of the elements common to both displays. Several of the elements are disposed so as to form groups of segments or zones, each group representing one digit of the digital display. Several others of the elements are disclosed radially to form an analogue display for simulating a parameter, such as time, by representing an hours hand and a minutes hand.
Claims7
A combined analogue and digital display, comprising:
- a substrate;
- a plurality of first display groups disposed on said substrate, each of said first groups being radially arranged about a point and being spaced from each other by an equidistant angular amount on said substrate and each of said first groups further including a plurality of individually energizable first elongated display elements aligned linearly along a radius to form an analogue display simulating the position of at least one hand on a dial;
- and
- a plurality of second display groups, each of said second groups including individually energizable second elongated display elements disposed on said substrate in proximity to said first elongated display elements, each of said second groups being arranged to cooperate with at least some of said first display elements to form at least two digital display arrays, each capable of selectively displaying any single digital character for displaying time.
