<P>PROBLEM TO BE SOLVED: To reduce the characteristic variance of a voltage-current conversion circuit which supplies a data signal to a data line for driving a transistor arranged in the pixel of an organic EL display device. <P>SOLUTION: The voltage-current conversion circuits 304 in a data driver 102 for driving the transistor arranged in the pixel are provided by two systems A and B, and R, G and B signals are supplied to them. The voltage-current conversion circuits 304 of the systems A and B are switched and controlled for every frame or switched and controlled for every frame and every line. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
