Abstract
An improved numeric display is based on the usual seven-segment display, but the segments are both curved and straight in the interest of making the display more legible than the usual segmented display. A particular feature is the division of the usual lower left-hand segment into three portions, all of which are activated simultaneously, as a result of which those numerals involving the lower left-hand segment and the bottom segment are enhanced in appearance. Moreover, the corners of the display are rounded, a feature which improves both the legibility and the appearance of the display.
Claims8
An improved numeric seven-segment display device for showing any single digit from 0 to 9, comprising a top, a right-upper, a right-lower, a left-upper, a left-lower, a middle and bottom segments, the totality of said segments forming a figure-8 with essentially vertical sides and horizontal top, middle and bottom, said bottom segment being thinner at its mid-portion than said top segment and being concave on its upper edge and convex on its lower edge, and extending at its left end into the bottom of the space normally occupied by the left-lower segment of a conventional seven-segment numeric display, said left-lower and bottom segments being mutually interposed and said bottom segment dividing said left-lower segment, said left-lower segment being in three portions, the first of said three portions extending from proximate the bottom of said left-upper segment to the left end of said bottom segment, the second of said portions having an essentially horizontal upper edge and a lower edge conforming to the upper concave edge of said bottom segment and the third of said portions lying beneath the left-hand end of said bottom segment, said second and said third portions having size, shape and position such that in combination with said bottom segment a strip is formed which has essentially the same transverse dimension as said top segment;
- and electric circuitry connected with said segments for selective actuation of same, said electric circuitry including electrical connections between said three portions of said left-lower segment so that said three portions are always actuated together.
