Abstract
Each of pixel circuits includes a light-emitting element, a first power line to supply the light-emitting element with a power-supply voltage, a driving transistor to control current to the light-emitting element, a sensing transistor whose gate electrode is connected to an end of the light-emitting element, a second power line connected to a drain electrode of the sensing transistor, and a first switching transistor connected between a source electrode of the sensing transistor and a sense line. The driving transistor controls sense current from the first power line to the light-emitting element in order to measure a voltage at an end of the light-emitting element. The sensing transistor supplies a source voltage to the sense line when the light-emitting element is being supplied with the sense current. A measurement circuit determines a voltage of the light-emitting element based on an output of the sense line.
