Abstract

A pixel driving circuit and a driving method thereof, and an array substrate are provided. The pixel driving circuit includes a data line (Data), a gate line (Gate), a first power supply line (ELVDD), a second power supply line (ELVSS), a reference signal line (ref), a light emitting device (D), a driving transistor (T7), a storage capacitor (C1), a reset unit, a data writing unit, a compensating unit and a light emitting control unit. The pixel driving circuit can compensate and remove non-uniformity in displaying caused by variances in threshold voltage among driving transistors.
