<P>PROBLEM TO BE SOLVED: To provide a driving circuit for a current driven device, which quickly precharges the current driven device and precisely writes a current signal, and to provide a current driven system provided with the driving circuit and the current driven device, and a driving method therefor. <P>SOLUTION: A precharge circuit 250 is provided with an N-channel transistor T1 for switch, and a reference potential Vb is applied to one of the source and the drain of the transistor T1, and the other is connected to a connection point A, and a precharge signal PC1 is applied to the gate. The reference potential Vb is a potential minimizing a precharge output potential in the case of 0 gradation display (black display) of a pixel 100, namely, a current flowing to a P-type transistor T35. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
