Abstract:
A display device comprising:a display panel having a luminescent layer, an array of scanning electrodes disposed on one surface of the luminescent layer and an array of data electrodes disposed on the other surface of the luminescent layer, the scanning electrodes perpendicularly crossing the data electrodes, capacitive pixels being formed at each intersection of both electrodes together with the luminescent layer, the pixels being arranged in a matrix;a scanning electrode driving circuit for supplying scanning voltages to the scanning electrodes; anda data electrode driving circuit for supplying data voltages to the data electrodes, wherein:the scanning electrodes are sequentially scanned by sequentially supplying the scanning voltages thereto;composite voltages consisting of the scanning voltages and the data voltages are imposed on the pixels thereby to activate the pixels to emit light; andthe pixels on a scanning electrode once scanned are charged by supplying turnaround current before the next scanning electrode is scanned to prevent the turnaround current from being supplied to the pixels on the scanned scanning electrode when other scanning electrodes are scanned.
