Abstract
The present invention provides an OLED pixel driving circuit and an OLED display panel. The OLED pixel driving circuit sets a third thin film transistor (T3) between a direct current voltage end (Vdd) and an organic light emitting diode (D), and manipulates a control signal (P) to control on or off of the source and the drain of the third thin film transistor (T3) for being capable of conveniently controlling the light emitting period of an OLED. The OLED display panel sets a third thin film transistor (T3) between a direct current voltage end (Vdd) and an organic light emitting diode (D) in the OLED pixel driving circuit of each sub pixel, and manipulates a first control signal (P1) and a second control signal (P2), of which the voltage levels are opposite, to respectively control every two adjacent pixels to be in a state that one emit light and the other dose not emit light, alternately for being capable of conveniently controlling the light emitting period of the OLEDs in the respective pixels for shortening the light emitting periods of the OLEDs in respective pixels and extending the lifetime of the OLED display panel.
