<P>PROBLEM TO BE SOLVED: To provide an organic thin-film EL display device whose driving voltage can be suppressed low and which does not have luminance variance with positions of pixels and is capable of luminance gray scale control even when the display device has high resolution, and a driving method thereof. <P>SOLUTION: Disclosed is the driving method for driving the organic thin-film EL display device by a current source connected to a voltage source of a driving voltage VCC while data electrodes are arranged on low-resistance-side wires and scanning electrodes are arranged on high-resistance-side wires in consideration of resistance values of wire electrodes of an X-Y matrix type organic EL display device and currents flowing to the wire electrodes, the driving voltage VCC being a specified voltage meeting the condition that the current source is in constant current operation without fail in spite of variance in wiring resistance with positions of pixels. <P>COPYRIGHT: (C)2007,JPO&INPIT |
