ABSTRACT:
A device for visually displaying alphanumeric characters by means of segments which are individually and selectively switchable between two operating states, one of which corresponds to visual perceptability of the segments themselves. The segments are arranged in identical, adjacent groups forming a repeating structure, wherein each group comprises first segments together defining a main configuration including two quadrilateral-shaped spaces arranged one above the other and open on their right-hand sides, second segments defining first and second subsidiary configurations disposed respectively at the lower left-hand corner, and the upper left-hand corner of the main configuration and each including a segment which extends substantially vertically from a respective corner of the main configuration itself, two third segments one of which occupies the upper left-hand portion of the lower quadrilateral-shaped space of the main configuration, and the other of which is located below the lower right-hand corner of the main configuration.
