Abstract
A pixel capable of displaying an image with uniform brightness. The pixel includes an organic light emitting diode (OLED), a first transistor for controlling an amount of current that flows from a first power source to a second power source via the OLED, and a second transistor coupled between a gate electrode of the first transistor and a bias power source, and configured to be turned on when a reset signal is supplied to a reset line, wherein a turn on time of the second transistor is configured to apply the bias power source to the gate electrode of the first transistor for at least 560 μs.
