Patent ID: 7202840

Claim:
A method for driving an organic electroluminescent display device, which includes an organic electroluminescent element between a set of scanning strips and a set of data strips, both sets crossing each other, and a data driver connected to the respective data strips provided with a constant current circuit, and which is driven by passive matrix addressing, comprising: placing a data strip in a high impedance state after supplying a constant current to the data strip from the constant current circuit in a selection period for applying a selection voltage to a scanning strip; and providing an organic electroluminescent element, the organic electroluminescent element having luminous efficiencies with respect to currents flowing therethrough falling in a variation range in a range of voltages applied across an anode and a cathode of the organic electroluminescent element, the applied voltages ranging from a voltage applied at an end of a rising time of voltage application to a voltage applied at an end of the high impedance section in the selection period.
