Patent ID: 7460093

Claim:
A method of driving an electronic circuit comprising: a driving transistor for controlling a current flowing through a driven element; a first switching element for turning on or off between a gate and a drain of the driving transistor; a capacitive element one end of which is connected to the gate of the driving transistor; a second switching element for turning on or off between the other end of the capacitive element and the drain of the driving transistor; a third switching element for turning on or off between a signal line and the other end of the capacitive element; and a fourth switching element for cutting off the current flowing through the driven element when turned off, regardless of the control of the driving transistor, wherein the method comprises: a first step of turning on at least the first and second switching elements, and then turning off the first and second switching elements; a second step of applying to the signal line a voltage corresponding to a current which is to flow into the driven element while the third switching element is turned on; and a third step of turning off the third switching element, and making the driving transistor keep flowing the current corresponding to the gate voltage of the driving transistor through the driven element by maintaining the fourth switching element in the on-state.
