Claim Text:
1. A pixel driving circuit, comprising: a first switch, having a first end for receiving a data voltage, a control end for receiving a first scan signal, and a second end for outputting the data voltage; a capacitor having a first end coupled to the second end of the first switch, and a second end; a second switch having a first end coupled to the second end of the first switch, a control end for receiving a second scan signal, and a second end; and at least one organic light emitting diode (OLED), having a first end coupled to the second end of the second switch, and a second end coupled to the second end of the capacitor; wherein: the first scan signal and the second scan signal are complementary; when the first switch is turned on, the data voltage is stored to the capacitor; and when the second switch is turned on, the first switch is turned off and the data voltage stored in the capacitor is outputted through the second switch to drive the at least one OLED.
