Abstract
The embodiments of the present disclosure provide a pixel driving circuit and a driving method thereof, an array substrate and a display apparatus, which is able to avoid an influence on a driving current of an active light emitting device caused by a drift in a threshold voltage of a driving transistor. The pixel driving circuit comprises a data line, a first scan line, a second scan line, a signal controlling line, a light emitting device, a storage capacitor, a driving transistor, a first switch transistor, a second switch transistor, a third switch transistor, a fourth switch transistor and a fifth switch transistor. The embodiments of the present disclosure may be applied to a display manufacture.
