Abstract
A pixel includes an organic light emitting diode (OLED), a first transistor connected to a driver and a first node, having a gate connected to a control line, a second transistor between to the first node and a second node, having a gate connected to a third node, a third transistor connected to an anode of the OLED, having a gate connected to the control line, a fourth transistor between the first node and a data line, having a gate connected to a scan line, a fifth transistor between the second and third nodes, having a gate connected to the scan line, a sixth transistor between an initializing line and the anode, having a gate connected to the scan line, a seventh transistor between the initializing line and the third node, having a gate connected to another scan line, and a storage capacitor between the driver and the third node.
