发明名称 Method and device for driving an electroluminescence matrix display
摘要 The invention concerns a method and device for driving an electroluminescence matrix display. According to the method succeeding images are formed on the display (1), whereby to form one image all the row electrodes (r1-r6) of the display are scanned through one by one with a constant voltage, and a column voltage corresponding to the desired instantaneous combination of luminance levels is formed for the column electrodes (c1-c2) in synchronism with the scanning of the row electrodes (r1-r6). According to the invention a voltage corresponding to the average modulation voltage (AV) of the column electrodes (c1-c6) is connected to at least a part of the non-selected row electrodes (r1-r6) to capacitively raise the column electrodes (c1-c6) by the amount of the average modulation level, and only the required column electrodes (c1-c6) are driven to the difference voltage in reference to the average modulation voltage (AV).
