摘要
PURPOSE: An organic electro-luminescence driving circuit and an organic electro-luminescence display device using the same are provided to reduce a power consumption due to resetting operations and peak currents. CONSTITUTION: An organic EL(Electro-Luminescence) element driving circuit includes a switch circuit, a peak current generator circuit(4), a reset inhibit circuit(6) and a determination unit. The switch circuit resets organic EL elements by setting anode sides of the organic EL elements to a predetermined potential through the terminal pins in the reset period. The peak current generator circuit generates a peak current overlapped on the driving currents of the organic EL elements. The reset inhibit circuit inhibits a resetting by the switch circuit and stops generation of the peak currents by the peak current generator circuit. The determination unit determines whether the driving current for the current display period is substantially the same as that in the display period of a next horizontal scan line. The reset inhibit circuit inhibits the resetting and stopping the generation of the peak current when the driving current for the display period of a current display period is substantially the same as that of a next horizontal scan line.
