Abstract:
Disclosed are a pixel circuit and method for driving the same, an organic light emitting display panel and a display device. Prior to the data signal is written into the control electrode of the driving transistor, a unified common voltage signal is input to the first electrode of the driving transistor. The common voltage signal, along with a threshold voltage of the driving transistor, is written into the control electrode of the driving transistor. It can be ensured that each time the data signal is written to the control electrode of the driving transistor, voltages of the control electrode and the first electrode of the driving transistor can jump by a unified potential, so as to avoid the variation of the voltage change in the control electrode which came as a result of the parasitic capacitance between the control electrode and the first electrode of the driving transistor.
