Electronic display apparatus

A display assembly, comprising

• a substrate;
• a plurality of identical coplanar groups of optically variable indicators on said substrate arranged adjacent each other in an array for cooperation with a scale;
• each of said groups of indicators being divided into a plurality of sub-groups of multiple indicators, at least one but not all of said indicators of each sub-group within each group being common to all sub-groups of that group;
• the indicators of each group being geometrically shaped such that each sub-group of indicators forms a differently shaped pointer whereby said pointers may be separately discerned when plural sub-groups within a group are simultaneously driven;
• and
• means for driving said sub-groups in response to measured parameters whereby plural measured parameters may be independently displayed.

A display assembly for a timepiece, comprising:

• a clock circuit for generating an output each minute and an output each hour;
• a substrate;
• a first set of indicators arranged in a radial pattern on said substrate;
• a second set of indicators arranged in a radial pattern on said substrate;
• at least one but not all of said indicators being common to both sets;
• first driver means coupled between said clock circuit and said first set of indicators for driving a sub-set of said first set of indicators to simulate the appearance of a mechanical minute hand in response to minute outputs from said clock circuit;
• second driver menas coupled between said clock circuit and said second set of indicators for driving a sub-set of said second set of indicators to simulate the appearance of a mechanical hour hand in response to hour outputs from said clock circuit;
• and
• said sub-sets of said first and second set of indicators being shaped such that said simulated hour and minute hands may be separately discerned when superimposed.

A day of the week display, comprising:

• a rectilinear array of seven electro-optical indicators having no indicia;
• five of said indicators being equally spaced apart from each other to form a group representing from left to right the days Monday, Tuesday, Wednesday, Thursday and Friday, respectively;
• the remaining two indicators being disposed one on each side of said group, each at a distance from its next adjacent indicator greater than the distance between the indicators of said group such that said group may be separately discerned apart from said remaining two indicators, said remaining two indicators representing the days Sunday and Saturday, respectively;
• and
• a clock circuit generating an electrical output each day and cooperating with said seven indicators for driving each of said indicators in timed sequence to effect an indication of the day of the week whereby the day of the week may be displayed without the use of indicia.

A display assembly, comprising

• a substrate;
• at least sixty identical coplanar groups of electro-optical indicator elements arranged adjacent each other in a radial array for cooperation with a scale;
• each of said groups containing:
• a first elongated rectangular element disposed along a radial line bisecting said group;
• a second elongated rectangular element shorter in length than said first rectangular element and disposed in an outer radial position adjacent said first rectangular element along said radial line;
• a first pair of polygonal elements disposed one on each side of said first rectangular element;
• a second pair of polygonal elements disposed one on each side of said first rectangular element;
• a third pair of polygonal elements disposed one on each side of said second rectangular element;
• and
• a pair of triangular electrodes disposed one on each side of said second rectangular element adjacent the radially outermost end thereof and cooperating with said second rectangular element to form an arrow-head therefor;
• means for driving said first rectangular element said first and second pairs of polygonal elements, and an adjacent element of the first pair of elements of each adjacent group to form a visually discernable pointer having a first shape and representing a first measured parameter;
• means for driving said first and second rectangular elements and said first, second and third paris of polygonal elements to form a visually discernable pointer having a second shape and representing a second measured parameter;
• and
• means for driving said first and second rectangular elements and said pair of triangular elements to form a visually discernable pointer having a third shape and representing a third measured parameter;
• said first, second and third shapes being such that they are separately discernable when superimposed.
