Abstract
A pixel driving circuit and a display panel are provided. The pixel driving circuit includes a driving transistor connected in series with a light-emitting element between a first power supply line and a second power supply line, a data transistor electrically connected to a gate electrode of the driving transistor, a boost module configured to load a boost input signal. An output terminal of the boost module is electrically connected to the gate electrode of the driving transistor to increase a voltage of the gate electrode of the driving transistor from a first voltage to the second voltage. A connection point between a first capacitor and a second capacitor is connected to the gate electrode of the driving transistor.
