The viewing and/or display device D with light-emitting diodes e arranged according to a matrix with n lines and p columns, comprises a separate connection for each diode e, and control means C for turning on or turning off predetermined connections so as to light or extinguish the associated diodes, and to obtain a representation of graphics or the equivalent. The control means C comprise, on the one hand, means M for maintaining an ignition or extinction signal on the connections according to the diode in question in order to allow, during a display phase, provision of permanent illumination of the graphics or the equivalent, and, on the other hand, editing means E for such graphics which include scanning means 4, 5 which are suitable, after the extinction of all the diodes, for sequentially producing a light pulse on each diode, and optical means J for indexing a diode upon the passage of the pulse, a validation 14 or erase command 15 for the diode in question being additionally provided. <IMAGE> |
