A device for controlling a display with a number of strings of light-emitting elements (particularly bulbs) connected in series to offer a aesthetically favorable jeu de lumiére, having, apart from a timing generator and a driving circuit for the display, a read only memory ROM, a programmable logic array PLA, two dividers and two address counters. With this device, all the aesthetically practical patterns can be repeated in desired times with varying speeds while requiring a very small storage capacity of the ROM, thus considerably saving the cost of production.
