Abstract
A pixel includes an organic light emitting diode (OLED); a first transistor between a driving power and a first node, having a gate connected to a control line; a second transistor between the first node and a second node, having a gate connected to a second electrode of a seventh transistor; a third transistor between the second node and an anode electrode of the OLED, having a gate connected to the control line; a fourth transistor between the first node and a data line; a fifth transistor between the second node and a storage capacitor; a sixth transistor between an initialization power and the anode electrode, the fourth to sixth transistors having gates connected to a scan line; the seventh transistor connected to the initialization power and the gate of the second transistor, having a gate connected to another scan line, all transistors being oxide semiconductor thin film transistors.
