Abstract

A pixel circuit and an OLED display including the same are disclosed. The pixel circuit includes a driving transistor having a double gate structure, the driving transistor including a first gate electrode electrically connected to a first node, a second gate electrode electrically connected to a second node, a first electrode electrically connected to a first power supply voltage, and a second electrode electrically connected to the anode of the OLED. The pixel circuit also includes a switching transistor including a gate electrode configured to receive a scan signal, a first electrode configured to receive a data voltage, and a second electrode electrically connected to the first node. The pixel circuit further includes a storage capacitor and a compensation capacitor including a first electrode electrically connected to the second node and a second electrode electrically connected to the first electrode of the driving transistor.
