<P>PROBLEM TO BE SOLVED: To reduce a luminance gradient of an organic EL display device due to resistance present on a common electrode wire. <P>SOLUTION: In the driving device of the organic EL display device, a voltage is outputted from a power circuit to a segment driver through a correcting circuit 25. The correcting circuit 25 has a current detection resistor 251 on a wire for supplying a current from the power circuit to the segment driver. A resistor 253 and a resistor 255, and a resistor 254 and a resistor 256 are connected to both ends of the current detection resistor 251 respectively, and the resistors 255 and 256 are grounded. A comparator 252 inputs a voltage (corresponding to the value of a current flowing through the current detection resistor 251) corresponding to a voltage applied to the current detection resistor 251 and outputs an output voltage corresponding to the input voltage. The power circuit switches the output voltage to the segment driver according to the output voltage of the comparator 252. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
