A driving compensation method for a pixel circuit includes: in a compensation phase of the pixel circuit, providing a preset signal to the control terminal of the driving transistor to write the preset signal to the control terminal of the driving transistor, to write internal loss voltage of the driving transistor to the first terminal of the driving transistor; wherein the compensation phase includes a first external compensation phase and a second external compensation phase; in the first external compensation phase, the preset signal is a sum of a reference signal and a threshold voltage of the driving transistor; in the second external compensation phase, the preset signal is the sum of the data signal and the threshold voltage of the driving transistor.
