Abstract:
1. A pixel driving circuit of an organic light emitting diode, comprising: a first transistor, comprising a first end for receiving a data voltage, a second end, and a control end for receiving a first scan signal; a capacitor, comprising a first end electrically connected to the second end of the first transistor, and a second end; a second transistor, comprising a first end electrically connected to a first voltage source, a control end, and a second end electrically connected to the second end of the capacitor; a third transistor, comprising a first end for receiving a first reference voltage, a second end electrically connected to the control end of the second transistor, and a control end for receiving the first scan signal; a fourth transistor, comprising a first end electrically connected to the control end of the second transistor, a second end electrically connected to the second end of the first transistor, and a control end for receiving a second scan signal; a fifth transistor, comprising a first end electrically connected to the second end of the capacitor, a second end, and a control end for receiving a driving signal; and an organic light emitting diode, comprising a first end electrically connected the second end of the fifth transistor, and a second end electrically connected to a second voltage source, wherein the first scan signal is complementary to the second scan signal.
