Abstract: A pixel includes a pixel circuit and an organic light emitting diode. The pixel circuit has first, second, third, and fourth transistors. The first transistor controls an amount of current flowing from a first driving power supply coupled to a first node to a second driving power supply through the organic light emitting diode. The turns on when a scan signal is supplied to a first scan line. The third transistor turns on when a scan signal is supplied to a second scan line. The fourth transistor turns on when a scan signal is supplied to a third scan line. The first transistor is a p-type Low Temperature Poly-Silicon thin film transistor and the third transistor and the fourth transistor are n-type oxide semiconductor thin film transistors.
