Pixel circuit, method of driving the same, and organic light emitting display device having the same |
摘要 |
A method of driving a pixel circuit includes initializing a driving transistor and a storage capacitor by simultaneously applying an initialization voltage and a first power voltage to a gate electrode of the driving transistor and the storage capacitor, respectively, diode-coupling the driving transistor, applying a data voltage to the storage capacitor, applying the data voltage to the gate electrode of the driving transistor by a coupling of a compensation capacitor coupled between the gate electrode of the driving transistor and the storage capacitor, and applying a current corresponding to the first power voltage and the data voltage to an organic light emitting diode that is coupled to the driving transistor. |
