Patent ID: 7649515

Claim:
A method of driving an electronic circuit having a driving transistor for controlling a current supplied by a power supply line that flows into a driven element, a first switching element provided between a gate and a drain of the driving transistor to be turned on or off, a fourth switching element provided between, and directly connected to, a drain of the driving transistor and the power supply line, a capacitive element one end of which is connected to the gate of the driving transistor, and a feed line that supplies an initial voltage, the method comprising: a first step of applying the initial voltage to the other end of the capacitive element to allow said current to flow into the driven element in a case in which the first switching element is turned on, and then turning off the fourth switching element to block said current, interrupting the application of the initial voltage to the other end of the capacitive element, and then turning off the first switching element; a second step of applying a voltage corresponding to said current flowing into the driven element to the other end of the capacitive element; and a third step of causing the driving transistor to make a current according to a held gate voltage flow into the driven element.
