Abstract
A pixel driving circuit is provided to include: a driving transistor; a data writing circuit configured to write a display data voltage from the data line to a first node in a display driving process, and sequentially write a sensing data voltage and a reset data voltage from the data line to the first node in a threshold voltage sensing process; a threshold compensation circuit configured to write a reference voltage from a reference voltage supply terminal to the first node and write a first compensation voltage to a second node in the display driving process, and write a second compensation voltage to the second node when a voltage at the first node changes from the reference voltage to the display data voltage; a sensing circuit configured to write an initialization voltage from the sensing line to the second node in the threshold voltage sensing process; a light emitting element.
