PIXEL AND ORGANIC LIGHT EMITTING DISPLAY DEVICE HAVING THE SAME

摘要

A pixel of an organic light emitting display device includes an organic light emitting diode, a driving transistor including a gate electrode coupled to a first node, a first electrode coupled to a second node, and a second electrode coupled to a third node, the driving transistor being configured to control a driving current through the organic light emitting diode based on a voltage of the first node, a first transistor coupled between the second node and a data line, the first transistor being configured to be turned on in response to a scan signal provided through a current scan line, a storage capacitor coupled between the first node and a high-power voltage line, the storage capacitor being configured to store a data signal provided through the first transistor, and an initialization block configured to initialize the first node based on a scan signal provided through a previous scan line.
