Pixel driving circuit and driving method thereof, display apparatus

摘要

The present invention provides a pixel driving circuit and a driving method thereof, and a display apparatus, which can raise starting point for writing a data, ensure time for writing the data, and avoid distortion of the written data. The pixel driving circuit comprises a reset module, a data write module, an output module and a pre-charging module, wherein during a period after a reset stage and before inputting of a row driving signal, the pre-charging module performs a step of pre-charging.
