摘要： A scan driver includes: a plurality of scan driving blocks including an output terminal outputting a scan signal to a scan line; a first transistor transmitting a voltage of a power source to the output terminal; a second transistor transmitting a clock signal to the output terminal; and a third transistor including a gate electrode connected to a node formed with a gate-on voltage turning on the second transistor, one terminal connected to the power source, and the other terminal connected to the gate electrode of the first transistor. The scan driver may reduce the influence of a leakage current even though application of the scan signal is increased, and a scan signal of a uniform voltage level may be output.

摘要： An organic light emitting diode display that includes pixels having organic light emitting diodes and driving transistors for supplying a driving current to the respective organic light emitting diodes. Also included is a compensator for receiving a predetermined voltage applied to a gate electrode of the respective driving transistors, finding a threshold voltage, mobility, and a change of mobility of the driving transistors, and determining a compensation amount caused by an input image data signal while sinking a predetermined current to a path of a driving current to the organic light emitting diode through a data line connected to the pixels. Further included is a timing controller for receiving the compensation amount, correcting the input image data signal, and transmitting the corrected image data signal and a data driver for generating a data voltage based on the corrected image data signal, and supplying the data voltage to the pixels.
