Abstract
The present application discloses an organic light emitting display panel, a driving method thereof and an organic light emitting display apparatus. The organic light emitting display panel comprises: a pixel array, comprising pixel regions in M rows and N columns; a plurality of pixel driving circuits each comprising a light emitting diode and a driving transistor for driving the light emitting diode, the light emitting diode being arranged in one of the pixel regions; and a plurality of pixel compensation circuits, each configured to provide a compensated light emitting control signal for a gate of the driving transistor to correct brightness of the light emitting diode in one of the plurality of pixel driving circuits. According to the present disclosure, the final light emitting current may be unrelated to the threshold voltage of the driving transistor, the carrier mobility and aging of the light emitting diode.
