    摘要: A pixel capable of realizing desired brightness and of displaying a uniform image is disclosed. In one aspect, the pixel includes an organic light emitting diode (OLED), a first transistor having a second electrode thereof coupled to an anode electrode of the OLED to control an amount of current supplied to the OLED in response to a voltage applied to a gate electrode thereof. The pixel also includes at least one second transistor coupled between the second electrode and the gate electrode of the first transistor, and a third transistor coupled between the second transistor and the gate electrode of the first transistor. The third transistor is turned off in a partial period of a period in which the second transistor is turned on.
