Abstract
A pixel driving circuit and a display panel are provided. The pixel driving circuit includes a scan line, a data line, a capacitor, a switch module, and a driving transistor. A scanning voltage is at a first level in a sampling phase and in a light-emitting phase, and at a second level in a data writing phase. A data voltage is at a high level in the sampling phase, and at a low level in the data writing phase and in the light-emitting phase. The capacitor includes a first capacitor-terminal and a second capacitor-terminal. The driving transistor includes a gate terminal electrically connected with the second capacitor-terminal, a source terminal electrically connected with the scan line, and a drain terminal configured to be electrically connected with the gate terminal in the sampling phase and be disconnected from the gate terminal in the data writing phase.
