Abstract:
A pixel capable of improving display quality may include an organic light emitting diode, a first transistor configured to control, in response to a voltage of a first node, current flowing from a first driving power source to a second driving power source via the organic light emitting diode, a second transistor coupled between the first node and a second electrode of the first transistor, and configured to be turned on when a scan signal is supplied to a scan line, a storage capacitor coupled between an initialization power source and the first node, a first capacitor coupled between the second electrode of the first transistor and a data line, and a second capacitor coupled between the first node and the second electrode of the first transistor. A display including such pixels also is disclosed.
