1. A multi-segment alphanumeric display comprising:
- a body comprising a planar surface with at least seven discreet segments with cavities, a lens to cover each of the segments, a bottom section comprising at least two light sources per segment, and electric circuitry connected with the light sources in each segment for selective actuation of the segments;
wherein the segment cavities in the body comprise partitioning of sufficient depth to prevent light bleeding from one segment to another;
wherein each segment cavity comprises a lip near the top of the cavity wherein each lens for each segment fits on the segment in the lip and a planar surface of each lens is flush with the planar surface of the body; and
wherein the lenses are a darker reddish in color, the body is of a different lighter color to allow lenses of unlit segments to be visible from a distance of 100 feet, and the light sources are high intensity light emitting diodes.

Abstract
A multi-segment alphanumeric display, such as a seven-segment display, is described. The display comprises a body including at least seven discreet segments. A lens to covers each of the segments. A bottom section comprising at least two light sources per segment is attached to the body. Electric circuitry is connected with the light sources in each segment for selective actuation of the segments. The segments in the body comprise partitioning of sufficient depth to prevent light bleeding from one segment to another.

3. An improved numeric seven-segment display device for showing any single digit from 0 to 9, comprising
a body comprising a planar surface with a top, a right-upper, a right-lower, a left-upper, a left lower, a middle and bottom discrete segments forming a figure-8 with essentially vertical sides and horizontal top, middle and bottom segments wherein each segment includes a cavity, a lens to cover each of the segment cavities, a bottom section comprising at least two light sources per segment, and electric circuitry connected with said light sources in each segment for selective actuation of the segments; -
wherein the segment cavities in the body further comprise partitioning of sufficient depth to prevent light bleeding from one segment to another;
wherein each segment in the body further comprises a lip near the top of the cavity to hold the lens, wherein each lens for each segment fits on the segment on the lip such that a planar outer surface of each lens is flush with the planar surface of the body; and
wherein the lenses are a darker reddish in color, the body is of a different lighter color to allow lenses of unlit segments to be visible from a distance of 100 feet, and the light sources are high intensity light emitting diodes. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
