Abstract

A device for controlling an electroluminescent matrix display by successive selection of its lines, including a column control circuit having circuitry capable of placing, at the beginning of the selection of a line, the display column at a precharge voltage based on the operating voltage of the previous line, the column control circuit also having circuitry capable of modifying the precharge voltage according to the difference between luminance instructions of the previous line and those of the selected line.
