Abstract
A pixel driving circuit, an organic light emitting display panel and a pixel driving method. The pixel driving circuit includes: a switching sub-circuit, a driving sub-circuit, a storage capacitor and a charge eliminating sub-circuit; the charge eliminating sub-circuit has a control terminal connected to a first scanning signal line, and other terminals connected to the first terminal of the driving sub-circuit, a cathode of the organic light emitting element (OLED) and a reference voltage terminal respectively, and can enable a potential between the anode and the cathode of the organic light emitting element to be reversed under control of the first scanning signal line.
