The invention provides an alphanumeric display module of four controllable cells, each constituted by electrically selectable elements that is able to provide significantly increased vocabulary of words considered essential for merchandising, such as “SAVE”and “BUY”, displayed in an acceptable unambiguous manner, while requiring less than 40 electric control lines, so that currently available 40 terminal memory storage devices can be employed in a simple and economical control circuit. The first two cells are of conventional “figure 8”configuration, each employing seven controllable elements. The third cell includes an upward right inclined element in its lower half thus, for example, removing ambiguity between “U”and “V”, while the fourth cell includes an additional vertical stroke of two separate elements between and parallel to the existing vertical strokes to permit, for example, acceptable display of “T”and “Y”and “W”. A selectable decimal period is provided at least between the second and third cells, and another may be provided between the third and fourth cells. A fifth cell can be provided consisting of a percentage sign and a cents sign having an oblique stroke in common. All of the thirty five elements can be controlled using only thirty six control lines, so that four are still available for basic control purposes, i.e., ground, power input, clock input and display backplane. It is also possible to provide the second cell with a downward right inclined element in the upper half to permit display of an unambiguous “N”and consequent display of the word “NEW”.

An alphanumeric display module comprising at least four display cells which from left to right as viewed by an observer are: (a) first and second cells which are figure eight cells having seven selectable elements, each cell having two spaced vertical sides each of two elements disposed one above the other, having horizontal top and bottom sides each of one element, and having a horizontal cross-bar of one element disposed between the top and bottom elements; (b) a third cell which is a figure eight cell having in addition a right upwardly inclined diagonal selectable element from the bottom left corner of the cell to the upper right corner at the junction of the cross-bar element and the lower right vertical element; (c) a fourth cell which is a figure eight cell having in addition two additional equal vertical selectable elements extending from top to bottom of the cell one above the other parallel to the vertical side elements and at least approximately midway between the vertical side elements; and (d) respective electric control leads connected to the cell elements for selective energization thereof; the display module including in addition a fifth cell to the right of the fourth cell, as viewed by an observer, the fifth cell comprising an upward right inclined oblique stroke element, a pair of simultaneously controllable period elements which together with the oblique element constitute a percentage sign, and a C-shaped element straddling the oblique element and constituting therewith a cents sign, and respective electric control leads connected to the oblique element, the pair of period elements and the C-shaped element for selective energization thereof.
