Patent abstract
To reduce variation in characteristics of a voltage-current conversion circuit for supplying a data signal to a data line for driving a transistor arranged in a pixel of an organic EL display device. Two sets A, B of voltage-current conversion circuits are provided in a data driver for driving a transistor arranged in a pixel, and RGB signals are supplied to these circuits. The voltage-current conversion circuits of sets A and B are controlled so as to be switched for every frame or every frame and line.
