OLED pixel compensation circuit and OLED pixel driving method

The invention discloses an OLED pixel compensation circuit and an OLED pixel driving method. The circuit comprises a threshold compensation module and a load driving module, wherein the threshold compensation module is used for observing and acquiring a threshold voltage of the load driving module and receiving an external data voltage, and then uses the threshold voltage to compensate the data voltage so as to acquire a driving voltage and store; the load driving module is used for receiving the driving voltage output by the threshold compensation module and converting the driving voltage into a driving current driving an organic light emitting diode. By using the method, an influence of changes of a supply voltage of the pixel compensation circuit on brightness of the organic light emitting diode can be compensated and an influence of a leakage current of a transistor which is in a cut-off state in the OLED pixel compensation circuit on a grid voltage of a driving transistor can be reduced so as to decrease the influence of the leakage current of the transistor on image quality.
