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.

摘要： A display device includes a display unit having a plurality of pixel, a scan driver that sequentially applies scan signals at a first voltage level to the plurality of pixels, a data driver that writes data by applying data signals to the plurality of pixels to correspond to the scan signals at the first voltage level, and a power source controller that supplies a first power source voltage and a second power source voltage to the plurality of pixels. The power source controller maintains the first power source voltage and the second power source voltage at the second voltage level while the data are written, and allows the plurality of pixels to which data are written to emit light by changing the first power source voltage into a third voltage level and the second power source voltage into the first voltage level after writing is complete.
