Abstract
A pixel driving circuit includes a driving transistor, a voltage stabilizing transistor, and a storage capacitance. A gate metal layer of a gate electrode of the voltage stabilizing transistor that serves as the control terminal of the voltage stabilizing transistor, and an active layer are constituted as a channel on-state capacitance, a ratio of an area of the channel on-state capacitance to a capacitance value of the storage capacitance is less than a preset value the area of the channel on-state capacitance is a directly opposite overlapping area between the gate metal layer and the active layer. This preset value is determined based on a ratio of a voltage fluctuation at a control terminal of the driving transistor to a potential voltage. A correlation between the channel on-state capacitance and the storage capacitance of the voltage stabilizing transistor is determined, so that a new capacitance configuration method is provided.
