<P>PROBLEM TO BE SOLVED: To provide an electronic circuit, an electronic device and an electronic equipment in which display quality is made superior and delay in the operation is reduced and to provide a driving method of the circuit. <P>SOLUTION: An operating voltage Vdx and a data current Idata are supplied to a holding capacitor C1 when first and second switching transistors Q11 and Q12 are turned on. An electrically conductive state of a driving transistor Q10 is set by the amount of electric charges corresponding to the current Idata held in the capacitor C1 and a current which passes the transistor Q10 is supplied to an organic EL element 21. Then, a first switch Q1 is turned off and a second switch Q2 and the transistor Q12 are turned on and a reset voltage Vr is supplied to the capacitor C1. Thus, the transistor Q10 is turned off and light emission of the element 21 is stopped. <P>COPYRIGHT: (C)2004,JPO |
