  • Patent number: 8094144
    Abstract: An electronic circuit, an electronic device, and an electronic apparatus are provided that are capable of display with good quality and reducing operation delay, and a method to drive the electronic circuit. First and second switching transistors are turned on and an operation voltage Vdx and a data-current Idata are transmitted to a holding capacitor. The conduction state of a driving transistor is set according to an electrical-charge amount corresponding to the data-current Idata held in the holding capacitor and a current that passes the driving transistor is transmitted to an organic EL element. Then, a first switch is turned off, a second switch and the second switching transistor are turned on, and a reset voltage Vr is transmitted to the holding capacitor, whereby the driving transistor is turned off and the organic EL element stops emitting light.
