摘要： A pixel driving circuit of an organic light emitting diode includes a first transistor including a first terminal, a control terminal and a second terminal and a capacitor including a first terminal and a second terminal. The first terminal and the second terminal of the capacitor are electrically coupled to the first terminal and the control terminal of the first transistor at a first node and a second node respectively. In a first period, a power source does not provide a power supply voltage to the first node, and a data voltage and a variable voltage are written in the first node and the second node respectively. In a second period, the power source provides the power supply voltage to the first node. The first transistor provides a driving current to an organic light emitting diode based on the voltage of the first node and the second node.
