Abstract
A pixel driving circuit for driving a pixel unit comprises a light emitting element, a first initiating transistor, a drive transistor with a first gate electrode and a second gate electrode, a controlling transistor, a resetting transistor, a second initiating transistor, a first storage capacitor, and a second storage capacitor. A gate electrode of the second initiating transistor receives the second control signal, a source electrode of the second initiating transistor is electrically connected to an anode of the light emitting element, and a drain electrode of the second initiating transistor is electrically connected to a source electrode of the second initiating transistor. The second initiating transistor controls the second storage capacitor to discharge through the light emitting element and resets the anode of the light emitting element.
