Abstract
An organic light emitting display comprises: a driving TFT comprising a gate connected to a node B, a drain connected to an input terminal of high-potential cell driving voltage, and a source connected to the organic light emitting diode through a node C; a first switching TFT for switching the current path between a node A and the node B in response to a light emission control signal; a second switching TFT for initializing the node C in response to an initialization signal; a third switching TFT for initializing either the node A or the node B in response to the initialization signal; a fourth switching TFT for switching the current path between a data line and the node B in response to a scan signal; a compensation capacitor connected between the node B and the node C.
