<p>An alpha-numeric display device comprises a plurality of elongate elements arranged in the form of a cross (6,7,8) and a diagonal cross (9,10,11,12) within a rectangle (1,2,3,4,5). A full alpha-numeric character set may be generated by approximately energizing selected elongate elements. The display device comprises twelve elements instead of the fourteen elements normally provided in such a display device thus reducing the number of electrical connections required and the information required to be stored in order to drive the display. The elongate elements may be formed as liquid crystal cells and a plurality of display devices may be formed into a multi character display arrangement. When addressing the display devices in matrix form a 4 x 3 matrix may be used instead of the 4 x 4 matrix required for a 14 element display.</p> |
