Abstract
A pixel driving circuit includes: a switching transistor, an energy storage capacitor, and a driving transistor. The data voltage is charged to the energy storage capacitor when the switching transistor is conducted. When the switching transistor is switched off, the energy storage capacitor discharges to the driving transistor, allowing the driving transistor to output a driving current to the light-emitting unit to drive the light-emitting unit to emit light. The control module is connected in series with the driving transistor. In a process of the driving transistor outputting the driving current to the light-emitting unit, the control module detects a value of the driving current and is disconnected when the value of the driving current exceeds a preset current range.
