The third transistor supplies a data voltage to a first electrode of the capacitor in response to a select signal. The fourth transistor outputs a current corresponding to its gate-source voltage, which is based on the voltage of the capacitor.

Each pixel circuit includes a driving transistor, a capacitor having one end coupled to a gate electrode of the driving transistor, a first switch coupled between the gate electrode of the driving transistor and a first main electrode, which is turned on in response to a first level of a first control signal for diode-coupling the driving transistor, and a second switch turned on in response to a second level of a second control signal to transmit current flowing out of the first main electrode of the driving transistor to a light emitting element. The second switch is turned on when the first switch is turned on for a first period longer than 0.05 μs and shorter than 2.5 μs. The second switch is turned on when the first switch is turned off.

摘要： A driver comprises odd-numbered stages configured to be driven by first and second clock signals and even-numbered stages configured to be driven by the second and third clock signals. Each stage is coupled to a corresponding emission control line, and includes a first driver, a second driver, and a third driver. In a first stage, the first and second drivers receive first and second start pulses and output first and second output signals, respectively. In each stage except the first stage, the first and second driver receives first and second output signals of a previous stage and outputs first and second output signals of each stage, respectively. In each stage, a third driver receives the first and second output signals of each stage and outputs an emission control signal to be transmitted to an emission control line coupled to each stage.
