ABSTRACT:
A current driver includes a gate line having a first and second nodes, K driving transistors, a terminal and a voltage generation section. The terminal receives a first current. The voltage generation section generates a bias voltage according to a current value of the first current. The gate line receives, at one of the first and second nodes, the bias voltage generated by the voltage generation section. Gates of the K transistors are connected between the first and second nodes of the gate line. In the voltage generation section, the relationship between the first current and the bias voltage is adjusted in the first mode, according to a current value of an output current flowing in a first driving transistor of the K driving transistors, and in the second mode, according to a current value of an output current flowing in a second driving transistor of the K driving transistors.
