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.
