US 2006/0231740 A1 · ELECTRONIC CIRCUIT, METHOD OF DRIVING ELECTRONIC CIRCUIT, ELECTRO-OPTICAL DEVICE, AND ELECTRONIC APPARATUS

Abstract

There is provided a method of driving an electronic circuit. The electronic circuit includes a light-emitting element that is interposed between a first electric supply line and a second electric supply line having different potentials and emits light by the supply of a current, a storage capacitor that holds a voltage between a first electrode and a second electrode, and a driving transistor that is interposed between the first electric supply line and the second electric supply line and has a gate terminal connected to the first electrode of the storage capacitor. The method includes: for a first period, applying a data potential according to a gray-scale level designated for the light-emitting element to the second electrode of the storage capacitor while electrically connecting an initialization wiring line supplied with an initialization potential to the first electrode of the storage capacitor; and for a second period subsequent to the first period, electrically connecting the second electrode of the storage capacitor to a source terminal of the driving transistor.
