Abstract
The present disclosure provides a pixel circuit and a driving method thereof, and an organic light emitting display apparatus. The pixel circuit includes: first to ninth transistors, a storage capacitor and a light emitting diode. T2 is used as a driving transistor, T3 is used as a switching transistor, T1, T2 and T3 form a threshold voltage sampling unit of T2, and T4, T8 and T9 form a compensation unit, and the compensation unit is used for compensating the IR Drop generated by a power supply voltage on a line.
