The first capacitor obtains the gate-source voltage of the first transistor according to the programming current flowing through the first transistor, and the second capacitor obtains the threshold voltage of the second transistor. Thereafter, the electrical charges held in the first capacitor element and the second capacitor element are capacitively coupled. By using the voltage obtained by capacitive coupling as the gate-source voltage of the first transistor, a constant current according to the programming current can be supplied to the light emitting element.n n n n Capacitor, Programming Current, Gate-Source Voltage, Transistor, Display |
